The prioritization incorporated staff’s institutional knowledge, and results from comprehensive condition assessments conducted by EPA and PG Environmental which are included in Appendix B & C. Using a Technical Assistance Grant from the EPA, PG Environmental worked collaboratively with DEM-WWD to create a CIP prioritization tool. DEM-WWD and PG Environmental implemented the County of Hawaiʻi Capital Improvement Program Scoring Matrix User Guide & 2023 Results included as Appendix A. The prioritization tool was used to create the initial CIP project priority list. After the execution of Administrative Order on Consent Docket No. CWA-309(a)-24-003 (Countywide AOC) the CIP list was revised to align with the requirements of the Countywide AOC. The most recent iteration of the CIP list aligns the CIP priority projects with all current executed enforcement documents. 1.

PAGE 8 3. Project Justification & Project Prioritization Table 4 – Project Justification & Prioritization Priority Ranking Project Justification 1 Pāhala Wastewater System The County is the current owner and/or operator of two (2) large capacity cesspools (LCC), that serve approximately 109 private residences in the Pāhala Community. LCCs are not an EPA-approved wastewater disposal method. The facilities are in violation and continue to violate the Safe Drinking Water Act. Under the 2024 Revised AOC, SDWA-UIC-AOC-2017-0002, The final deadline for the County to close the large capacity cesspools is January 22, 2027. 2 Nāʻālehu Wastewater System The County is the current owner and/or operator of three (3) large capacity cesspools (LCC), that serve approximately 164 private residences in the Nāʻālehu Community. LCCs are not an EPA approved wastewater disposal method. The facilities are in violation and continue to violate the Safe Drinking Water Act. The final deadline for the County to close the large capacity cesspools is December 31, 2027. 3&4 Hilo WWTP Rehabilitation and Replacement Phase I & II (COH Hilo WWTP Upgrades) The Hilo WWTP serves the sewered areas of the Hilo community. The WWTP was constructed in the early 1990s and was originally designed to provide secondary treatment of wastewater for an average dry weather and peak wet weather wastewater flow of 5.0 mgd. Current dry weather flows are approximately 2.7 -2.8 mgd. Recent condition assessments and a resulting master plan have identified a range of critical system deficiencies within the WWTP which threaten reliable treatment and the ability to provide a safe working environment for operations and maintenance staff. These deficiencies include severe concrete deterioration, malfunctioning equipment, and safety hazards. In addition, influent five-day biochemical oxygen demand (BOD) and total suspended solids (TSS) concentrations are greater than those which served as the basis of the original plant design. Moreover, the existing condition of the facility poses a threat to the safe and normalized operations of the WWTP. As the Hilo WWTP is the only wastewater facility that serves the region, it is a critical facility. The proposed project will restore the original capacity of 5.0 mgd average dry weather flow. 5 Kealakehe WWTP Headworks (COH – Kealakehe WWTP Rehabilitation and Replacement) The KWWTP was initially constructed in 1993 to replace the original activated sludge-based Kailua Wastewater Treatment Plant (WWTP). The facility is currently permitted to treat 5.3 million gallons per day (mgd) to secondary treatment levels. The KWWTP unit processes consist of a Septage Receiving Station (SRS), a PAGE 9 Priority Ranking Project Justification Headworks Facility, which includes screenings and grit removal, Aerated Lagoons, and an Effluent Pump Station. Support facilities include the emergency power system, an Administration Building, and an Operations Building. Several necessary improvements/repairs have been identified for the headworks facility, septage receiving facility. 6 Pua Sewer Pump Station and Force Main Replacement The project proposes to rehabilitate the existing 24-inch force main from the Pua Sewage Pump Station (SPS) to the Hilo Wastewater Treatment Plant. The County did experience a break of the existing force main back in 2011. During that repair, it was discovered that the liner in the pipe was starting to peel away from the inner wall causing potential blockage. 7 Kula’imano WWTP Rehabilitation and Replacement (COH – Kulaʻimano and Pāpa‘ikou Dewatering and Barminutor Replacement) The existing influent barminutor systems at Kula‘imano WWTPs are at the end of their useful life and are proposed to be replaced with rotary screens. The existing grinders are installed within a concrete channel in the headworks building with limited area for improvements. 8 Pāpaikou WWTP Rehabilitation and Replacement (COH – Kulaʻimano and Pāpa‘ikou Dewatering and Barminutor Replacement) The existing influent barminutor systems at Pāpa‘ikou WWTPs are at the end of their useful life and are proposed to be replaced with rotary screens. The existing grinders are installed within a concrete channel in the headworks building with limited area for improvements. 9 Hale Hālāwai FM (COH – Hale Hālāwai SPS Renovation & Force Main Replacement The existing 12-inch in diameter, 900 linear foot long cast iron force main was originally constructed in 1971. Replacement is needed due to the age and condition of the force main. The cast iron pipe material has deteriorated from both internal and external corrosion. The consequences of failure for the Hale Hālāwai force main are substantial, due to its proximity to valuable coastal shoreline and the area is heavily used by pedestrians. Failure of the force main would result in closure of the popular tourist destination of Kailua Bay. 10 Kealakehe SPS and FM Replacement (COH – Kealakehe SPS Renovation and Force Main Replacement) Design Phase Only – The existing 9,300 linear foot, 24” ductile iron force main from the Kealakehe Sewer Pump Station to the Kealakehe WWTP was installed in the early 1990s. The force main is identified as a single point of failure and previously operators have observed portions of the internal lining separating from the internal pipe. The project proposes to complete the design for a redundant 24” force main for installation in parallel with the existing force main. PAGE 10 4.

The Wastewater Division is responsible for the operation and maintenance of 120 miles of sewer mains, 16 pump stations, 7 treatment facilities, and the closure of the large capacity cesspools in Pāhala and Nāʻālehu. The Wastewater Division accepts approximately 5 million gallons of wastewater for treatment per day, cleans and inspects approximately 20 miles of sewer lines each year. Wastewater-Division Administration Fiscal Year 2023-2024 Position Organization Chart PAGE 17 Currently, DEM-WWD staff are managing multiple projects and programs. As projects or programs advance into different phases DEM- WWD will adjust staffing levels. DEM-WWD will leverage consultants through professional service contracts or hire internal staff based on the permanence of our needs. In situations where large amounts of staffing support is needed for a short duration of time, the DEM- WWD will likely leverage professional services contracts and in other situations where new programs are created then DEM-WWD will choose to add new staff positions. This will support the County in supporting capital improvement projects or the start of regulatory programs necessitated by the changing regulatory environment. Draft Reorganization and Staffing Needs The Department of Environmental Management (DEM) is currently facing a critical staffing shortage, with eighty-six vacant positions, including twenty-six within the Wastewater Division. To ensure compliance with the Administrative Order on Consent (AOC), DEM has prioritized filling these vacancies and creating additional positions to address increased workload demands. Concurrently, DEM is developing a draft reorganization plan, as outlined in the charts on the following pages. This plan is still subject to review by the County of Hawai‘i Department of Human Resources, the United Public Workers (UPW) and the Hawai‘i Government Employees Association (HGEA) for approval and implementation. To meet the AOC Appendix 1 Planning and Reporting requirement (section II.9.g) for an organizational chart demonstrating staffing needs, DEM will submit the draft reorganization to the aforementioned entities prior to the January 31, 2027 deadline. Benchmarking wastewater administration and operations in other municipalities, DEM is confident that this reorganization will enhance efficiency, accountability, and redundancy to meet AOC deliverables within budget and timeline constraints. The final submittal will provide detailed information on position reallocations and new roles. PAGE 18 PAGE 19 PAGE 20 PAGE 21 7. Estimated operations and maintenance costs for each project. At this time COH DEM WW Division has an overall cost associated with the operations and maintenance of the existing facilities. The recently approved Mayor and Council adopted budget for Fiscal Year 2024-2025 was estimated at $26,919,005. The fiscal year starts July 1 and ends June 30 of the following year. The expenses are allocated for day-to-day operational activities, such as: PAGE 22 1. Utilities: Costs related to electricity, water, and gas used in the treatment process. 2.

Evaluation of current AMP and CIP efforts. Recently the County submitted the Asset Management Implementation Plan to the EPA in conformance with the Countywide AOC. In March of 2019 PG Environmental provided condition and risk assessment reports for use by DEM-WWD. These reports included data from an initial condition assessment of vertical and horizontal wastewater assets. The data has since been incorporated into our asset management system for use in prioritizing capital improvement projects. Capital improvement projects are differentiated between vertical/facility projects and horizontal/collection system projects. Asset management does provide DEM-WWD a report that identifies all NASSCO level 4 & 5 defects for collection system or horizontal assets repair prioritization. DEM-WWD leverages this report to determine if the defect will be corrected internally by our own O&M staff or incorporated into a CIP project for implementation. Asset management is building the necessary database of condition scores for critical vertical components for use by DEM-WWD. This will be completed early next year and we will be leveraging the information for use in our CIP program.

The CIP Scoring Matrix is an Excel-based spreadsheet tool titled COH CIP_Scoring_Matrix. This document accompanies the spreadsheet file and contains:  Background information about COH’s CIP and development of the CIP Scoring Matrix,  Instructions for using and updating the CIP Scoring Matrix, and  Results and discussion from the initial (2023) round of scoring. PG and WWD team members developed the CIP Scoring Matrix and scored 17 proposed CIP projects. This initial round of scoring helped to calibrate and refine the CIP Scoring Matrix while ranking the projects based on their projected costs and benefits. The 17 projects range in scope from collection system improvements, such as rehabilitating sewer pump stations (SPSs) and installing new pipelines, to rehabilitation and construction of wastewater treatment plants (WWTPs). The projects were chosen as the most critical among dozens of needed wastewater infrastructure improvements on the island. Many of the projects also have implementation deadlines dictated by an EPA-issued administrative order on consent (AOC). The CIP projects and their 2023 CIP Scoring Matrix rankings (based on total score) are presented in Table 1, below. The CIP Scoring Matrix also ranks projects by their cost benefit (presented in County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results Executive Summary vi Table 4). Section 4 of this report provides further information and discussion about the 2023 CIP Scoring Results.

INTRODUCTION COH funds wastewater CIP projects primarily through County general obligation bonds and federal/state government grant and loan programs. Projects totaling less than $50,000 are not considered by COH to be “capital improvements” and can therefore be funded through user fees and other revenue sources. As a result, the County’s capital improvement program must accommodate projects that range from tens of thousands of dollars in capital costs (e.g., new pumping equipment) to hundreds of millions of dollars in capital costs (e.g., wastewater treatment plant rehabilitation). The CIP Scoring Matrix uses EPA’s Augmented Alternatives Analysis (AAA) process, which gives water utilities a systematic and objective approach for prioritizing water and wastewater infrastructure capital investments based on community-specific needs and goals. The AAA process uses a scoring system to rank proposed “alternatives” based on their estimated costs and projected performance in a framework of Goals, Objectives, Criteria, and Metrics. Community decision- makers are then able to allocate available funding and resources for the alternatives based on the rankings from the AAA. In 2023, concurrent with the development of the CIP Scoring Matrix, the WWD/PG Environmental Team used the CIP Scoring Matrix to score and rank 17 of COH’s most critical proposed capital improvement projects. These projects were chosen for the initial round of scoring from a backlog of over 100 needed wastewater system capital improvement investments. The WWD/PG team ranked the projects based on Total Score, which represents the overall benefit of implementing each project as determined in the Goal, Objectives, Criteria, and Metrics, as well as by Capital Cost Benefit Score, which measures the benefit of implementing each project against each dollar spent in capital cost. COH is subject to an EPA-issued AOC that contains implementation deadlines for many critical wastewater capital improvement projects. Therefore, the 2023 CIP Scoring Matrix rankings were driven by COH’s obligation and commitment to regulatory compliance, but future rankings may rely more heavily on other COH goals once compliance with the AOC is achieved. Each year, WWD will update the CIP Scoring Matrix with new projects and evaluate and update the Goals, Objectives, Criteria, and Metrics. New projects may come from the existing backlog or may be newly proposed based on evolving system needs. At the time that the COH CIP Scoring Matrix was being developed, WWD was in the process of implementing an asset management program, supported by the NEXGEN software platform, which includes procedures for collecting asset condition and performance data. Appendix A provides additional details on how asset risk and criticality scores are calculated based on asset condition and used within the asset management system. As more asset data becomes available in the future, WWD should utilize this data in the CIP Scoring Matrix. The CIP Scoring Matrix is best suited for comparing projects of similar scales and costs, so WWD may consider multiple cost tiers of CIP scoring in the future. For example, projects totaling less than $1 million in capital cost could be evaluated in one version of the CIP Scoring Matrix, while projects totaling $1 million or more in capital costs could be evaluated in another version. This may provide a more useful cost-benefit assessment in which larger scale projects are not deprioritized simply because they are drastically more expensive to implement. The 2023 CIP Scoring Matrix has been used to score 17 of COH’s most critical projects, which are all estimated to be multimillion dollar investments, so multiple tiers of scoring were not necessary. Table 2 on the next page, presents estimated implementation deadlines and brief descriptions of each of the 17 projects.

CIP SCORING MATRIX OVERVIEW The CIP Scoring Matrix spreadsheet is organized into tabs that are linked to each other using formulas. The following subsections describe the organization and function of each tab. 2.1 Goal-Objective-Criteria-Metric The organization of Goals, Objectives, Criteria, and Metrics is referred to as the “Goal-Objective- Criterion-Metric framework.” Each Goal is broken into several discrete Objectives. Each Objective has at least one Criterion by which a project's contribution toward achieving the Objective will be measured. Each Criterion has at least one quantitative or qualitative Metric, as well as a weighting value (scale of 1 to 10) that reflects the relative importance of the Criteria, with 10 being most important. Each Metric also has a Performance Range, which defines the point scale for rating each project, and Scoring Guidance, which provides the user with instructions and tips for determining the Metric score for each project. The ‘Goal-Objective-Criteria-Metric’ tab lists the Goals, Objectives, Criteria, and Metrics by which the projects are evaluated. Figure 1 shows an image of the Goal-Objective-Criteria-Metric’ tab in the 2023 CIP Scoring Matrix. There are no formulas on the ‘Goal-Objective-Criteria-Metric’ tab. However, formulas on the other tabs reference the cells on the ‘Goal-Objective-Criteria-Metric’ tab. Each column in the Goal-Objective-Criteria-Metric’ tab is described in more detail below. Goals: Goals are at the top of the Goal-Objective-Criteria-Metric framework and represent high-level programmatic missions. Goals should be broadly stated and should align with community-level initiatives. For the 2023 CIP Scoring, WWD identified three high-level Goals for wastewater capital improvement projects that aligned with the COH Mayor’s administration priorities and DEM’s core values: Goal 1: Protect and improve public health/safety and improve community livability. Goal 2: Enable safer and more efficient operations and maintenance (O&M). Goal 3: Build a self-sustaining wastewater system. Objectives: Objectives are more specific than Goals, and multiple Objectives can contribute to a common Goal. In the 2023 CIP Scoring Matrix, six Objectives contribute to Goal 1: “Protect and improve public health/safety and improve community livability.” The first Objective within Goal 1 (denoted Objective 1.1) is “conserve natural resources and promote sustainability.” Criteria: Criteria are indicators by which progress towards the Objectives can be measured. Multiple Criteria can be used to measure progress towards a single Objective. However, all but one of the Objectives in the 2023 CIP Scoring Matrix used only a single Criterion. For example, Objective 1.1 contains a single Criterion (denoted “Criterion 1.1.1), “Improve efficiency of natural resources consumption.” Criteria Weightings: Each Criterion is assigned a weighting value between 1 and 10 that reflects the relative importance of the Criteria, with 10 being most important. Multiple Criteria may have the same weighting value and it is not necessary to have Criteria with weighting values at each integer between 1 and 10. For example, three Criteria may have a weighting value of 10 while no Criteria have a weighting value of 9. County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results CIP Scoring Matrix Overview 5 Metrics: Metrics are quantitative or qualitative project attributes, ideally backed up by scientific data, which are expressed in a numeric point system. Multiple Metrics can be used to score a single Criterion. However, it is not recommended to use more than three Metrics per Criterion, because the mathematical influence of each Metric on the project Total Score is diminished by each additional Metric used to score a given Criterion (refer to Equations 1 and 2). The 2023 CIP Scoring Matrix employs a -5-to-+5-point scale. Some Metrics utilize the entire range of the scale, while others utilize only the positive or negative side of the scale. Performance Ranges: Each Metric must have a performance range that identifies what numeric or qualitative attributes correspond with each possible score. Some Metrics may not need to utilize the full point scale. For example, in the 2023 CIP Scoring Matrix, Metric 1.2.1.1, “proximity of the project to streams wetlands, or coastline” is scored on a scale of 0 to +5 because it is not possible for a project to be located a negative distance from something. When setting performance ranges, it is important to remember that negative scores will decrease a project’s Total Score, and positive scores will increase its Total Score. For Metrics that do not have available scientific data to define performance ranges, qualitative descriptions may be used. In the 2023 CIP Scoring Matrix, most Metrics used quantitative performance ranges such as a scale from “increases net O&M labor demand by 2.5 [full time equivalents] FTEs” (-5 points) to “decreases net O&M labor demand by 2.5 FTEs” (5 points). However, other Metrics for which data was not readily available have performance ranges such as scaling from “no/neutral impact” (0 points) to “high net positive impact” (5 points). Scoring Guidance: The Scoring Guidance for each Metric provides instruction to the user on how to score projects accurately, fairly, and objectively. Scoring Guidance should identify any applicable data sources as well as procedures for collecting and interpreting the data and may include instructions for scoring different types of projects. When developing the Goals, Objectives, Criteria, and Metrics by which to evaluate projects, it is important to focus on technical attributes of projects, rather than attributes that could be subjective or otherwise result in unintended advantages for some projects over others. For example, when developing the 2023 CIP Scoring Matrix, the WWD/PG team considered using a Criterion that awarded points to projects that already had some or all their needed funding secured. This Criterion would have contributed to a Goal identified by WWD to implement projects in a timely manner, since projects with committed funding could theoretically be shovel-ready faster than projects with unsecured funding. However, this Criterion was ultimately omitted to preserve an objective comparison of projects based on their technical merits; the current funding status of the projects may have been influenced by preferences of individual decision makers or other subjective circumstances and as such should not be used to avoid inducing bias into the scoring.

County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results CIP Scoring Matrix Overview 7 2.2 Project Scoreboard The Project Scoreboard calculates and displays the scores for each project based on the inputs in the ‘Goal-Objective-Criteria-Metric’ tab and the Project Scoring Forms, including Capital Cost, Capital Cost Benefit Score, Annual O&M Cost Benefit Score, Total Score, and individual Criteria and Metric scores. The Project Scoreboard references cells from the ‘Goal-Objective-Criteria-Metric’ tab and Project Scoring Form sheets. The Project Scoreboard is shown in Figure 2. Figure 2. Image of the 2023 CIP Scoring Matrix ‘Project Scoreboard’ tab. Note that only the scores for the first Objective within Goal 1 are shown in this example. The rest of the scores are accessed by scrolling right on this tab. O&M Cost Benefit Scores in column E show an error “#DIV/0!” where O&M costs were not known because the project was not far enough into the design process for O&M costs to be accurately estimated. County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results CIP Scoring Matrix Overview 8 2.3 Calculating Project Scores The “Total Score” for each project represents the cumulative projected performance of the project within the Goal-Objective-Criteria-Metric framework, as expressed by Equation 1: 𝑻𝑺= ෍ 𝑪𝒊∗𝑾𝒊 𝒊 [1] Where: 𝑇𝑆 = Total Score 𝐶௜ = Raw score for Criterion i 𝑊௜ = Weighting value for Criterion i The raw score for each Criterion, 𝐶௜ , is calculated using Equation 2: 𝑪𝒊= 𝒎ഥ [2] Where: 𝑚ഥ = The average of scores for all Criterion i Metrics The Capital Cost Benefit Score for each project is calculated using Equation 3: 𝑪𝑪𝑩𝑺=𝑻𝑺 𝑪𝑪∗𝟏𝟎ି𝟔 [3]* Where: 𝐶𝐶𝐵𝑆 = Capital Cost Beneϐit Score 𝑇𝑆 = Total Score [see Equation 1] 𝐶𝐶 = Capital Cost The O&M Cost Benefit Score for each project is calculated using Equation 4: 𝑶𝑴𝑪𝑩𝑺=𝑻𝑺 𝑶𝑴𝑪∗𝟏𝟎𝟒 [4]* Where: 𝑂𝑀𝐶𝐵𝑆 = O&M Cost Beneϐit Score 𝑇𝑆 = Total Score [see Equation 1] 𝑂𝑀𝐶 = O&M Cost *The factors of 10ି଺ and 10ସ in Equations 3 and 4 are applied so that the capital and O&M cost benefit scores can be expressed in similar scales. However, it is important to note that the total score, the capital cost benefit score, and the O&M benefit score are not evaluated on a common mathematical scale. For example, the 4.0 capital cost benefit score of one project is not better than its 2.8 O&M cost benefit score; the capital cost benefit score of a project should only be compared against the capital cost benefit scores of the other projects. Sorting each score column in descending order gives the ranking order for that scoring category. County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results CIP Scoring Matrix Overview 9 2.4 Project Score Forms Each project to be evaluated in the scoring process needs to have a fully filled out ‘Project Score Form’ tab in the CIP Scoring Matrix spreadsheet. This is where details about the project, including the project name, description, estimated costs, and individual Metric scores are stored for reference by the ‘Project Scoreboard’ tab. When scoring a project, select a score for each Metric and provide a brief rationale for the selected score. Scoring input cells are identified with white fill. An example Project Score Form from the 2023 CIP Scoring Matrix is shown in Figure 3. If changes to the Goal-Objective-Criteria-Metric framework are made, the ‘Project Score Forms’ will need to be updated accordingly. Section 3 contains additional instructions for updating the CIP Scoring Matrix. Costs: The 2023 CIP Scoring Matrix used overall project cost. However, if comparing projects that have partial funding from a source or sources outside COH (e.g., state revolving fund or grants), projects could be compared based on the net cost to the County. This would mean subtracting any funding that is being born by other entities and thereby improving the cost benefit score of those projects. It may be advantageous to distribute the project scoring process by Metric among multiple staff, such that each staff member’s contribution corresponds with their day-to-day responsibilities. For example, engineering staff could assign scores for Metrics that pertain to construction timelines, project locations, and system-wide impacts. Similarly, operations staff could be tasked with assigning scores for Metrics that pertain to O&M demands and occupational safety. This sort of distributed approach will add efficiency and consistency to the scoring process. No matter the exact approach, it is important to involve as many staff as possible in the scoring process to achieve project scores that are as objective as possible.

County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results Updating the CIP Scoring Matrix 11 3. UPDATING THE CIP SCORING MATRIX The steps to updating the CIP Scoring Matrix are described below. Step 1: Revise the ‘Goal-Objective-Criteria-Metric’ tab to reflect COH’s current wastewater infrastructure initiatives and priorities. This process should involve holding meetings with COH leadership and stakeholders. If wastewater infrastructure needs and priorities have recently been determined as part of other COH planning efforts, they can also be used to update the ‘Goal-Objective-Criteria-Metric’ tab. For the 2023 CIP Project Scoring, the PG/WWD team utilized public input about wastewater goals, as well as information about cesspools in COH that was collected by the Cesspool Conversion Working Group. When updating the ‘Goal-Objective-Criteria-Metric’ tab, rows may be added or deleted, and cells combined, to change the new framework Goal-Objective-Criteria-Metric by which projects are evaluated. There are no formulas to update on the ‘Goal-Objective-Criteria-Metric’ tab. However, formulas on the other tabs reference the cells on the ‘Goal-Objective-Criteria-Metric’ tab. When considering new or revised ways to score Metrics (e.g., using asset management system data), update the scoring guidance (column G) for each Metric accordingly. Division or Department meetings should be held to ensure consensus on the ‘Goal-Objective-Criteria-Metric’ framework, including the weighting values that are applied to each Criterion. Once the ‘Goal-Objective-Criteria-Metric’ tab has been revised, the next step is to update the Project Scoring Forms to reflect the new framework. The ‘Project Score Forms’ must be adjusted such that each Goal has a section broken out by Objective, then by Criterion, and then by Metric (refer to Figure 1). Each Metric must have a cell to enter a numeric score, as well as a cell to record the rationale for the score (refer to Figure 3). In the 2023 CIP Scoring Matrix, drop down menus were used for selecting the numeric scores. Ensure that the blue and grey cells are referencing the appropriate cells on the ‘Goal-Objective-Criteria-Metric’ tab. It is easiest to make these changes to a single ‘Project Score Form’ and then copy that form into new tabs for each subsequent project. Step 2: Edit the ‘Project Scoreboard’ tab to reflect the revised ‘Goal-Objective-Criteria-Metric’ framework and to appropriately reference the ‘Project Score Forms’. As shown in Figure 2, each Criterion needs to have a column for a raw score as well as a column for a weighted score. Additionally, each Metric under the Criterion needs to have a column to the right of the Criterion score columns. The raw and weighted scores for each Criterion are computed with Excel formulas using Equation 2. The Total Score for each project is the sum of the weighted score for each of the Criteria (refer to Equation 1). The cost benefit scores are calculated by dividing the Totals Score by the project’s estimated Capital and O&M Costs (refer to Equations 3 and 4, respectively). Ensure that each project being evaluated has a row on the Project Scoreboard, and that each cell in the Metric columns is referencing the appropriate cell on that project’s ‘Project Score Form’. Step 3: Project Scoring. Once updates from Steps 1 and 2 have been made to the CIP Scoring Matrix, project scoring can commence. This involves reviewing the available data and information for each project (including project costs and descriptions), selecting scores for each Metric, and entering a written rationale for each score. As scores are entered into the ‘Project Score Forms,’ the ‘Project Scoreboard’ should populate with the scores for each Metric and compute the Criteria scores, Total Score, and Cost Benefit Scores.

Most of the 17 projects were not far enough into the project design process for O&M costs to be accurately estimated. However, if needed, O&M Cost Benefit Score project rankings may be generated using the CIP Scoring Matrix once O&M costs estimates are known. O&M Cost Benefit Score project rankings may be useful if the CIP planning process is being driven by annual budgeting priorities more than capital budgeting priorities. As seen in Table 3, Phase 1 of the Hilo WWTP Rehabilitation and Replacement project scored the highest Total Score of the 17 projects, but also carries the highest capital cost. The estimated capital cost for Phase 1 of the Hilo WWTP Rehabilitation and Replacement project is approximately three times greater than the next most expensive project (Naalehu Wastewater System). Despite having the highest Total Score, Phase 1 of the Hilo WWTP Rehabilitation and Replacement project ranks last among the 17 projects when evaluated by Capital Cost Benefit Score. The 17 CIP Projects fall into two distinct categories: 7 WWTP projects and 10 collection system projects. Some notable trends present themselves when comparing the project rankings within the two project categories. Figure 4 compares 2023 CIP Total Scores and Ranking and Capital Costs Benefit Scores and Rankings for just the WWTP projects. Note that the Pahala and Naalehu wastewater system projects County of Hawaii Capital Improvement Program Scoring Matrix User Guide & 2023 Results 2023 Scoring Results 14 involve constructing new WWTPs and new collection systems. In general, WWTP projects are more costly and result in greater benefits than collection system projects, so the Pahala and Naalehu projects have been categorized as WWTP projects for the purposes of this comparison. Figure 4. Comparison of WWTP Projects’ Total Score Ranking and Capital Cost Benefit Ranking. Figure 4. Comparison of WWTP Projects’ Total Score Ranking and Capital Cost Benefit RankingFigure 4 shows that the Total Score Rankings and Capital Cost Benefit Rankings are essentially reversed for WWTP projects, with the highest Total Score Ranking also having the lowest Capital Cost Benefit Score Rankings, and vis versa. Note that the Hilo WWTP Rehabilitation and Replacement Phase II project does not follow this trend, ranking as the second highest Total Score and the third highest Capital Cost Benefit Score. The Hilo WWTP Rehabilitation and Replacement Phase II project is also unique in that it relies on the prior implementation of one of the other projects (Hilo WWTP Rehabilitation and Replacement Phase I).

Comparison of Collection System Projects’ Total Score Ranking and Capital Cost Benefit Ranking. Much like the comparison of the WWTP projects’ Total Score Ranking and Capital Cost Benefit Ranking, the Total Score Rankings and Capital Cost Benefit Rankings have an inverse relationship; most of the collection system projects with the highest Total Score Rankings also having the lowest Capital Cost Benefit Score Rankings, and vis versa. However, the Keōpū and Project 19 projects stand out as having favorable rankings in both Total Score and Capital Cost Benefit Score. County of Hawaii Capital Improvement Project Scoring Matrix User Guide Conclusion 16 5. CONCLUSION The CIP Scoring Matrix provides WWD with a formalized objective process for ranking proposed wastewater infrastructure capital investments based on their technical merits and estimated implementation costs. The CIP Scoring Matrix’s Goal-Objective-Criteria-Metric framework can be modified to reflect the priorities and initiatives of COH decision makers as they evolve from year to year. As projects are started and completed, new projects can be proposed and added to the CIP Scoring Matrix to be scored and ranked against the existing projects. The 2023 CIP Scoring Results show an inverse relationship between projects’ Total Scores and their Capital Cost Benefit Scores. In general, projects with the highest Total Scores also had the highest capital costs and the lowest Capital Cost Benefit scores. Projects that did not follow this trend and scored well in Total Score and Cost Benefit Score included Phase 2 of the Hilo WWTP Rehabilitation and Replacement Project, the Keōpū SPS and FM project, and the Project 19 SPS and FM upgrades. Among the collection system projects, the Kōlea SPS and FM project ranked highest according to Total Score and the Wailuku Gravity Main project ranked highest according to Capital Cost Benefit Score. Among the WWTP projects, Phase 1 of the Hilo WWTP Rehabilitation and Replacement Project ranked highest according to Total Score and the Kula’imano WWTP Rehabilitation and Replacement project ranked highest according to Capital Cost Benefit Score. Section 3 of this report contains instructions for annually updating the CIP Scoring Matrix. Depending on the magnitude of changes being made, updates to the CIP Scoring Matrix could be time-consuming. It is recommended that, if possible, the same staff member(s) make changes to the CIP Scoring Matrix spreadsheet from year to year so that efficiency can be gained in the updating process. At the time of the 2023 CIP Project Scoring, WWD was also in the process of implementing an asset management program, supported by the NEXGEN software platform. As the asset management system is further integrated into WWD operations and asset data are obtained, the CIP Scoring Matrix should be updated to incorporate that data. Specifically, asset condition and criticality scores will be essential for maximizing the utility of the CIP Scoring Matrix. County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 17 APPENDIX A: IMPLEMENTING ASSET RISK/CRITICALITY SCORING County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 18 Introduction: This document expands on asset risk/criticality scoring within Asset Management System (AMS) implementation, referencing the existing AMS documentation, and providing practical guidance based on best practices for your WWTP. By implementing a systematic approach to this scoring system and condition assessment, the WWD can achieve the following benefits as outlined in the EPA's Administrative Order of Consent (AOC):  Prioritize Maintenance Efforts vs. CIP Projects: Allocate resources effectively towards maintaining critical assets and deferring unnecessary capital improvement projects (CIPs).  Optimize Resource Allocation: Focus resources on assets with the highest potential impact on operations in case of failure.  Make Data-Driven Decisions: Use objective data to guide repair, replacement, and long-term planning for WWTP assets. Asset Risk/Criticality Score: The asset risk/criticality score is a numerical value representing the potential consequences of an asset failure on the WWTP's operations. Calculation: Risk Score = Probability of Failure (POF) x Consequence of Failure (COF) Details on integrating this score into your AMS can be found in the existing AMS implementation documentation. Probability of Failure (POF): Definition: The chance of an asset experiencing a functional failure within a specific timeframe (e.g., next year). Scoring System: Develop a scoring system that assigns points to factors influencing POF. Higher scores indicate a greater chance of failure. Here's a simplified approach to get you started:  1 Point: Minimal impact on factors like maintenance history, industry benchmarks, operating conditions, and condition assessment.  2 Points: Moderate impact on any of the factors mentioned above.  3 Points: Significant impact on any of the factors mentioned above. Weighting System (Optional): For a more nuanced approach, consider assigning weights to each factor based on its relative importance to POF in your specific WWTP. County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 19 Calculation: The total POF score is the sum of the weighted scores from each influencing factor. Assessment Factors:  Maintenance History: o Lower scores for assets with consistent preventive maintenance programs. o Higher scores for assets with frequent breakdowns, neglected maintenance, or a history of exceeding recommended maintenance intervals.  Industry Benchmarks: o Consider factors like asset age, remaining useful life, and typical failure rates for similar equipment based on industry data. Assets nearing the end of their expected lifespan might receive higher scores.  Operating Conditions: o Higher scores for assets operating at or exceeding capacity or exposed to harsh chemicals (e.g., strong acids/bases). o Lower scores for assets under less stress.  Condition Assessment: o Integrate the overall condition assessment score (discussed later) into the POF calculation. Assets in poor condition with significant deterioration are more likely to fail. Asset Failure Types: Consider these four primary types of asset failure when assessing POF:  Mortality: The asset physically fails or ceases to perform its intended function altogether.  Financial Inefficiency: The asset becomes too expensive to operate and maintain, making its replacement more economical.  Capacity: The asset remains operational but can no longer handle the required treatment volume.  Level of Service: The asset functions but fails to meet the desired level of service in areas like safety, water quality, recreation, habitat, or biodiversity. Condition Scoring: Assessment: Both the parent asset (e.g., primary clarifier) and its individual components (e.g., scraper mechanism) should be assessed. Scoring System: Choose a system that suits your needs:  Simple 1-to-5 Scale: o 1: Needs Immediate Attention County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 20 o 2: Poor o 3: Fair o 4: Good o 5: Excellent  Weighted System: Assign values to different condition categories (e.g., structural integrity, functionality, remaining useful life) with weights reflecting their relative importance. Interpretation: Define clear interpretations for each score level. Ensure the scoring system aligns with your AMS for consistency. Condition Assessment Standard Operating Procedure (SOP): Develop an SOP outlining roles and responsibilities for condition assessment:  Operations: Identify immediate issues through the AMS, such as subtle changes in performance, sound, or operating parameters. Reroute work orders with their assessment to the Maintenance team.  Maintenance: Conduct physical inspections to identify signs of wear and tear. Diagnose and repair mechanical problems. Reroute work orders with their assessment to the Engineering team if needed.  Engineering: Utilize engineering principles and analyze data to identify underlying causes of problems. Asset Risk/Criticality Score The asset risk/criticality score is a numerical value that represents the potential impact of an asset failure on the WWTP's operations. It's calculated by multiplying the probability of failure (POF) rating by the consequence of failure (COF) rating. Refer to the AMS implementation documentation for details on integrating this score into the AMS. Probability of Failure (POF) Definition, Scoring, and Assessment POF refers to the likelihood of an asset failing within a specific timeframe (e.g., next year). Here's a breakdown of how POF is defined, scored, calculated, and assessed:  Definition: The chance of an asset experiencing a functional failure that disrupts its intended operation.  Scoring: A scoring system is developed to assign points to factors influencing POF. Higher scores indicate a greater chance of failure.  Calculation: The total POF score is the sum of the weighted scores from each influencing factor.  Assessment: Factors impacting POF include: o Maintenance History: Assets with consistent preventive maintenance receive lower scores, while those with frequent breakdowns or neglected maintenance get higher scores. County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 21 o Industry Benchmarks: Consider factors like asset age, remaining useful life, and typical failure rates for similar equipment based on industry data. o Operating Conditions: Assets operating at or exceeding capacity or exposed to harsh chemicals receive higher scores due to increased stress. Assets under less stress receive lower scores. o Condition: The overall condition assessment score (discussed later) must also be factored into the POF. Asset Failure Types There are four primary types of asset failure to consider when assessing POF:  Mortality: The asset physically fails or ceases to perform its intended function altogether.  Financial Inefficiency: The asset becomes too expensive to operate and maintain, making its replacement more economical.  Capacity: The asset remains operational but can no longer handle the required treatment volume.  Level of Service: The asset functions but fails to meet the desired level of service in areas like safety, water quality, recreation, habitat, or biodiversity. Condition Scoring The condition assessment of an asset plays a crucial role in determining POF. Here's a breakdown of condition scoring:  Both the parent asset and its individual components (child assets) should be assessed.  Scoring System: Choose a 1-to-5 scale or a more detailed weighted system that assigns values to different condition categories.  Interpretation: Define clear interpretations for each score level. Here's an example using a 1-to-5 scale: o 1: (Needs Immediate Attention): The asset is in critical condition and requires immediate repair or replacement to avoid failure. o 2: (Poor): The asset shows significant signs of wear and tear and may need attention soon. o 3: (Fair): The asset is in average condition with some minor issues, but it is still functional. o 4: (Good): The asset is in good condition and functioning well, with minimal signs of wear. o 5: (Excellent): The asset is in top condition and performing at its best. Condition Assessment Standard Operating Procedure (SOP)  Operations: Operators are responsible for identifying immediate issues like subtle changes in performance, sound, or operating parameters through the AMS. They should reroute work orders with their assessment to the Maintenance team. County of Hawaii Capital Improvement Project Scoring Matrix User Guide Appendix A 22  Maintenance: Mechanics identify signs of wear and tear through physical inspection. They diagnose and repair mechanical problems and/or reroute work orders with their assessment to the Engineering team.  Engineering: Engineers focus on design, optimization, and long-term planning for the treatment plant. They utilize engineering principles and analyze data to identify underlying causes of problems. They also assess how different components work together and the impact of equipment failure on the entire treatment process. APPENDIX B County of Hawai’i Department of Environmental Management Wastewater Division Risk Assessment Report Vertical Assets Southwest Environmental Finance Center / PG Environmental under EPA Contract No. EP-R9-16-02 March 2019 1 Summary Under contract from the United States Environmental Protection Agency (EPA) Region 9, staff from PG Environmental and the Southwest Environmental Center (collectively, the PG Team) worked in coordination with staff from WWD to develop a framework and establish a standard operating procedure (SOP) for assessing the potential of failure (POF) and consequence of failure (COF) for the County of Hawai’i Department of Environmental Management Wastewater Division’s (WWD’s) vertical wastewater assets1. The resulting framework/SOP describes a 1 to 5 scale for both POF and COF as well as the process and different criteria to be used in determining how an asset should be ranked. To collect the information necessary to determine risk for vertical assets, the PG Team, along with WWD staff, visited each pump station and wastewater treatment plant on both sides of the island (east and west) and directly viewed each asset (when safely visible). Asset information was collected, and ratings were given for POF and COF, along with condition and useful life (additional attributes to be used to inform decision-making). The operator and technical support staff’s knowledge of each asset’s performance, failure history, and maintenance history, as well as visual observations and any other performance-related information were taken into consideration for determining POF and COF. Once all data was collected, it was downloaded into an Excel spreadsheet to allow for further analysis. In all, the PG Team evaluated 1,026 separate vertical assets and found about 50% of the utility’s vertical assets are in the low risk category, 36% are in the medium category, 9% are in the medium-high category, and 5% are in the high-risk category. The overall risk analysis demonstrates that while there are assets classified as high risk and medium-high risk, most of the assets are not in these categories. These results show WWD can take a prioritized approach to reducing overall risk that may not be as onerous as previously thought. 1 Included in the document, County of Hawai’i Department of Environmental Management Wastewater Division: Asset Criticality SOP and Framework. The PG Team’s analysis showed the majority of WWD’s high-risk assets are located at the Hilo WWTP, with 36 of the 51 total high-risk assets at that facility (see Table A3 in Appendix A for additional details specific to the Hilo WWTP assets). Vertical Asset Risk Assessment Report 2 Introduction An asset management program includes five core components: • current state of the assets; • level of service; • criticality / risk; • life cycle costing; and • long-term funding. The criticality component of asset management, also referred to as risk, is a fundamental component that helps inform decision-making in determining the most advantageous way to spend scarce resources – both personnel and financial. While all portions of asset management are important, understanding criticality and using it in decision-making can have some of the most dramatic effects on the overall operation of the organization. Criticality is based on the idea that some assets are more critical to the sustained operations of the facility than others. Knowing which assets are more critical to an operation, or pose the most risk if they become inoperable, can aid in determining how to spend funds, where to deploy personnel resources, how to manage an individual asset or collection of assets over time, and how to plan for capital improvements. Two major components contribute to determining criticality. The first is probability of failure (POF), or how likely an individual asset is to fail. The second is consequence of failure (COF), or how significant are the impacts if the asset does fail. These two factors are ranked and then multiplied together to indicate an overall risk score. POF X COF = Risk POF and COF can be scored on any scale a utility chooses, based on the desired level of detail and complexity. Scales of 1 to 5 or 1 to 10 are typical, which will result in risk scores of 1 to 25 or 1 to 100 respectively, with the lowest outcomes being the lowest risk and the highest number being the highest risk. A rank of “0” is never used because no asset is completely without any risk of failure or consequence. Asset risk scores can be used to evaluate assets in various ways. Assets can be examined individually, as contributing to the risk assessment of an entire facility (e.g., pump station or treatment plant) or portion of a facility (e.g., headworks, primary treatment, etc.), or they can be used to show overall risk for the entire utility. The data included in this report can be used for any one of these analyses. Vertical Asset Risk Assessment Report 3 Visualizing Risk Risk can be depicted in a variety of ways. Figure 1 provides an example visual representation of how risk scores are distributed based on POF and COF. Visualizing risk allows a utility operator to quickly identify assets needing immediate or near-immediate attention (i.e., high risk). This also functions as a useful tool to quickly inform decision-makers on which assets to prioritize for more-thorough analysis to mitigate overall risk. High Risk In the example above, assets that are highly likely to fail and would cause serious consequences if they did (i.e., high POF and COF) would be considered “high risk” assets and would fall within the red box in the upper right-hand corner. Moderate Risk Assets with 1) high probability of failure but a low consequence, 2) with a low probability of failure but a high consequence, or 3) those with a moderate probability of both would be considered “moderate risk” and appear in the boxes at the bottom right and top left, or near the center of the chart. Low Risk Assets with a low probability of failure and a low consequence of failure would be considered “low risk” and fall within the box in the lower left-hand corner. Tables 1 through 3 provide additional examples of asset risk visualizations based on real-world examples. In the first example, each asset at the Banyan Sewage Pump Station (SPS) is listed in Table 1, in the order of its risk score. High-risk scores are highlighted in red, medium-high risk scores are highlighted in orange (Note: The Banyan SPS had no assets in this range), medium-risk assets are highlighted in yellow, and low-risk assets are highlighted in green.

Determining Risk for Vertical Assets2 The PG Team and staff from the Wastewater Division (WWD) worked together to develop a framework and establish a standard operating procedure (SOP) for assessing POF and COF of vertical assets. For this project, vertical assets have been defined as those components that are primarily above ground and located within treatment facilities and pump stations. The framework describes a 1 to 5 scale for both POF and COF as well as different criteria to be used in determining how an asset should be ranked. To collect the information necessary to determine risk for vertical assets, the PG Team, along with WWD staff, visited each pump station and treatment plant on both sides of the island (east and west) and directly viewed each asset (except for submersible pumps). Asset information was collected, and ratings were given for POF and COF, along with condition and useful life (additional attributes to be used to inform decision-making). The operator and technical support staff’s knowledge of each asset’s performance, failure history, and maintenance history, as well as visual observations and any other performance-related information were taken into consideration for determining POF and COF. 2 This report focuses solely on vertical assets. The risk assessment of horizontal assets necessitated a slightly different approach, which is described in a separate document.

The document also describes the four basic ways an asset can fail (i.e., failure modes), which include: • Mortality: Complete loss of use of an asset (e.g., collapsed pipe, fractured pump drive, etc.). • Level of service: The asset’s performance level no longer meets the needs of the customer or the utility. This can be caused by the declining functionality of an asset or increased performance demands from the utility of its customers. • Financial inefficiency: Maintaining or repairing an asset would be costlier than replacing it. For example, it may be financially more favorable to replace an older motor with a new, more energy-efficient motor that will provide operational savings over time, even though upfront costs would be greater. • Capacity: The asset no longer performs at or provides sufficient capacity. For example, even if a pipe is in good condition, it may no longer provide enough capacity to meet volume demands. In collecting data, a failure mode code can be entered to indicate the predominant mode of failure. In many cases, the expected mode will be Mortality, but it is important to consider the other three. Table 4. Probability of Failure Criteria POF Factor Criteria Comments 1 Asset is brand new or like new. Failure not anticipated within the foreseeable future. 2 Asset is not brand new but shows no more than cosmetic signs of wear and tear. Failure is not anticipated in the near future (generally, not within the next 10 years or so). 3 Asset shows signs of operational or physical decline but has not yet entered a potential failure state. Asset may show light to moderate rust, some light to moderate wear and tear, be nearing but not at physical capacity. Asset’s normal maintenance frequency needs to be reviewed to see if an increase is needed to sustain a factor of 3 and prevent a condition of 4 or 5. 4 Asset is in potential failure—showing signs of failure, such as cracks, root intrusions, I/I, vibration, noise, excessive rust—but is still delivering all or most of the required service (i.e., not in functional failure mode). Functional failure not expected within the next year, but within the next few years. The potential failure issues will need to be addressed to prevent a functional failure. Functional failure occurs when the asset is in one of the four failure modes described above. 5 Asset is already in failure mode (see failure mode definitions above) or expected to fail within 1 year. A failure mode code can be added to note the means of failure (Level of Service, Mortality, Financial, Capacity) Vertical Asset Risk Assessment Report 7 Consequence of Failure (COF) Factors Table 5 describes the criteria developed for assessing the COF of an asset, which are included in more detail in the Asset Criticality SOP and Framework. The document also describes factoring in the ability to use redundant systems when considering COF. Table 5. Consequence of Failure Criteria COF Factor Criteria 1 No identifiable consequences. Less than $10,000 in repair costs. 2 $10,000 to $49,999 in repair costs. Short term disruption to traffic or business or operations (less than 4 hours). Bypassing (without violating permit) for less than 3 days. 3 $50,000 to $99,999 in repair costs. Disruption to businesses. Disruption to traffic. Disruption to septic haulers. Disruption to staff or regular operations. Bypassing (without violating permit) for more than 3 days. 4 Damage to other assets and/or private property. Potential to negatively harm the environment; potential to cause impacts to endangered species. $100,000 or more in costs related to repair. May make some minor news report. 5 Health and safety of employees and/or public at risk. Exceedance of permit limits. Politically problematic/becomes a major news story. Data Analysis and Results Once all data was collected, utilizing the Fulcrum data collection application, it was downloaded into an Excel spreadsheet to allow for further analysis. Several steps were taken to prepare the raw data to be used for risk assessment purposes, including consolidating entries into a more useful format, deleting duplicate entries and entries for assets that are no longer in operation (i.e., reconciling WWD’s pre- existing inventory data with more-recent data generated in the field during this effort), and reviewing data quality to identify and correct any apparent errors. The PG Team collected data on 1,026 separate vertical assets3. The inventory was completed by identifying the assets at each pump station and treatment plant within the WWD utility. There are assets from seven (7) wastewater treatment plants (WWTPs) and 16 pump stations included in the risk assessment. 3 Note that the vertical asset inventory shows over 1,400 assets. Parent assets that were broken into child assets were not evaluated at the parent level, but are included as separate in the inventory to show the relationship of the associated child assets; risk for the parent assets in these cases can be evaluated by analyzing the risk of all the child components. Vertical Asset Risk Assessment Report 8 Data analysis was compiled for each facility – each pump station and WWTP – as well as for the entire system (all pump stations and treatment plants on both sides of the island). Data for each individual facility is presented in Appendix A. A summary of the overall risk is provided is subsequent sections. Overall Risk As can be seen in Table 6, about 50% of the utility’s vertical assets are in the low risk category, 36% are in the medium category, 9% are in the medium-high category, and 5% are in the high-risk category. Table 7 shows the total number of WWTP assets in each risk category and Table 8 shows the same for pump station assets. The analysis also showed the majority of WWD’s high-risk assets are located at the Hilo WWTP (see Appendix A for additional details specific to the Hilo WWTP assets). The overall risk analysis demonstrates that while there are assets classified as high risk and medium-high risk, most of the assets are not in these categories. These results show WWD can take a prioritized approach to reducing overall risk that may not be as onerous as previously thought. Table 6.

Percentage of Low Risk Assets by Pump Station Vertical Asset Risk Assessment Report 15 Addressing High-Risk Assets There are multiple ways to address high-risk assets. These assets can be repaired, rehabilitated, or replaced. Further, the utility can act to reduce the consequences of failure in addition to or instead of actions to reduce the probability of failure. Determining which approach to take depends on many factors: • Underlying integrity of the asset: Assets with a high degree of underlying integrity, can be repaired because after the repair, the asset will still have sufficient life to make the repair investment worthwhile. • Cost: The cost of a repair versus rehabilitation versus replacement is a major factor, and there are a variety of scenarios to consider when deciding. For example, if the cost of replacement is much higher than rehabilitation, and rehabilitation will provide almost as much overall asset life as the replacement would, it is likely that rehabilitation is the best-case scenario. Additionally, if repair is very inexpensive and may result in a few years of extra life while the utility seeks funding for replacement, or if the repair will provide many more years of asset life (as described in the case above), repair may be a reasonable option. Further, if the additional asset life gained by replacement makes up for any additional cost of replacement, the asset should be replaced. • Ability to tolerate failure: If the consequence of failure is so grave that failure cannot be tolerated, then the asset should probably be replaced or at least rehabilitated to reduce the overall risk. In these cases, repairing the asset may not be sufficient in reducing the risk. • Level of service impacts: If continuing to repair the asset negatively impacts the utilities desired level of service, the asset may need to be rehabilitated or replaced. For example, if a pump failure causes backups in the sewer and repairs reduce but do not eliminate backups, a replacement that eliminates the backups (at least for the foreseeable future) may be more desirable from a customer perspective. • Remaining useful life: The remaining useful life of the asset based on a repair, rehabilitation, and replacement should be considered in determining which option is best. For example, if the repair would provide two (2) years of remaining useful life, rehabilitation 50, and repair 65, rehabilitation may provide the most risk reduction at a reasonable cost. If the repair provides five (5) to 10 years of remaining useful life and greatly reduces the probability of failure, while the rehabilitation would provide 25, and the replacement would provide 40 years, the repair option may be the most favorable if cost of the other options is too high or the funding is not available. • Reduction in consequence of failure: In addition to actions that can be taken to reduce the probability of failure (repair, rehabilitate, replace), actions can be taken to reduce the consequence of failure. These can include installing or increasing redundancy, having spare parts on hand, or providing specialized training to staff to make repairs easier and faster (i.e., being able to respond before a serious consequence has occurred). The factors discussed previously are just some that need to be considered in the decision-making; there is not always one “correct” response for each situation. Each case must be considered individually to determine the most favorable outcome for the given scenario. Specific actions for WWD will be evaluated and discussed with the utility before including them in the Condition Based Assessment report. Vertical Asset Risk Assessment Report 16 Using Risk Data to Inform Program Implementation Risk data can be used by utilities to inform modifications in program implementation with the goal of reducing risk of an asset, group of assets, or facility. For example, if pumps are typically showing up as high-risk assets, perhaps the utility’s maintenance program is insufficient to keep the pumps from failing prematurely. If this were to be the case, the maintenance program should be thoroughly evaluated to see if additional activities need to be done or if the frequency of the activities needs to change. To determine effectiveness, the pump life can be examined over time to see if it is increasing or to see if failures are decreasing due to the program adjustments. Risk data can also be used to help calibrate the anticipated useful life of a specific type of asset and inform long-term planning. For example, a utility may expect its pumps to last 20 years. However, the pumps may operate very well for 10 years but then increase in failures in years 11 through 15 until it is very difficult and financially inefficient to continue to keep the pumps running. In this case, the time horizon for pump replacement should be shortened. Next Steps While it is very important to assess the risk of the individual assets, it is also important to look at the risk in two additional ways: • Risk related to subsystems of the overall facility or utility (i.e., the risk of an individual pump station failing or the headworks of a treatment facility failing). • Risk related to the utility (i.e., the entire WWD utility, all assets on both the east and west sides of the island). Risk data for individual assets is not sufficient, by itself, to assess the risk of a system or subsystem. Additional considerations must be brought into the analysis to perform this type of risk assessment. This additional information would include: • Type of redundancy for the overall system (e.g., can a pump station handle the load if another pump station is shut down). • Consequences that happen if that subsystem is completely shut down. • Other than asset failure, what could cause the pump station or WWTP to fail (e.g., flooding, tsunami, electricity failure). • Damage that may occur to other subsystems based on the failure of that subsystem. • Possibility of environmental damage due to the subsystem failure. • Possibility of public health or employee harm. The PG Team will continue to work with WWD to review and verify the information contained in this report and use the data in addressing the items above. This more holistic analysis will be considered and included in the Condition Based Assessment report. Vertical Asset Risk Assessment Report 17 Recommended Additional Step As a recommended next step, WWD could evaluate system risk as a whole. This evaluation would involve looking at the utility’s overall resiliency and incorporating entirely different factors than those evaluated for this effort, such as the ability of the entire system to withstand natural disasters – hurricanes, tsunamis, volcanic eruptions, fires – as well as other types of emergencies – pandemics, vandalism, mass employee turnover. This would be an opportunity for the utility to consider how the utility has withstood these types of events in the past as well as the ability to withstand them in the future. This risk relies on and builds upon the risk assessments of individual assets and sub-systems. For example, if a tsunami were most likely to knock out “Pump Station A” and “Pump Station A” is highly critical as identified in the analysis of risk related to subsystems, it would be very problematic. If “Pump Station A” also includes numerous assets with high risk, the potential for serious impacts would be even greater. This expanded risk analysis also attempts to consider the potential for events that the utility has not been thinking of or preparing for. In other words, “what aren’t we expecting?” The greatest problems often come from what we are not expecting, rather than what we are.

In general, these can be separated into vertical assets (e.g., pump stations and treatment plants) and horizontal assets (e.g., conveyances and connections). This report focuses on the horizontal assets. The horizontal asset data most relevant to this report are related to pipes, manholes, services, and discharges, and are mostly located in the Wastewater Division’s (WWD’s) geographic information system (GIS) and closed-circuit television (CCTV) inspection videos/records. However, it has been found that there is only sufficient information to do a detailed analysis of WWD’s pipe segments. The assessment revealed significant data gaps exist in GIS for characterizing services and discharges. Another major data gap observed is the lack of information showing whether pipe segment defects were repaired. A fair amount of data does exist for manholes; however, they are considered by WWD to be integrated into the pipe system and get managed accordingly (i.e., as part of the pipeline and not individually). The PG Team also found that the quantity of CCTV data is currently too low to be statistically significant, only about 5.7% of the entire collection system. Also, the same pipes are often televised multiple times due to concerns related to defects or clogs; therefore, a true risk assessment for every pipe segment is not possible due to limited documented and representative data. In order to make best use of the data that is available in WWD’s GIS and from past CCTV efforts, the PG Team rated potential of failure (POF) for those segments with existing CCTV data as well as implemented a process to prioritize segments in the entire collection system based on specific criteria defined by WWD staff. Discussions were also held with WWD staff to determine different criteria that may lead to problems in a pipe segment. Pipes with a greater likelihood of problems would be considered higher priority for further investigation using CCTV in the future. Of the pipes ranked from the CCTV data, 7% were high POF, 26% were medium POF, and the remaining 67% ranked low POF. The prioritization part of the assessment yielded 179 high priority segments, 1,136 medium priority pipes, and 2,418 low priority pipes. The PG Team found that high POF segments and high priority segments did necessarily correlate, meaning WWD may have to reconsider the ranking factors. More likely, a greater sample of CCTV data is needed to determine a meaningful correlation, or lack thereof. These efforts (described in more detail in the report below) should only be viewed as a starting point for risk assessment. Further data collection (extensive) and quality control is needed to perform a proper and complete risk assessment. A detailed description of the methods and preliminary analysis of priority pipe segments is presented in the report. Within this document, the PG Team has also offered recommendations for improving data collection, management, and analysis of horizontal asset data, as well as strategies for implementing a more effective CCTV program. Risk Assessment Report: Horizontal Assets 2 Background Horizontal assets refer to those assets that are located within the service area or what is commonly referred to as “out in the field.” These types of assets are typically responsible for the linear conveyance of wastewater from the point of collection to the treatment facility. Typical assets of this type include pipe, manholes, pipeline valves (e.g., air release valves), and service connections. Vertical assets are those assets included within pump stations and treatment plants, such as such as pumps, motors, electrical controls, tanks, treatment units, blowers, and disinfection units. Horizontal and vertical assets are typically separated within asset management because managing the assets as well as data collection, storage, and analysis related to each set of assets, is considerably different. For example, there are often many, many identical horizontal assets (e.g., as many as several hundred pipe segments with the same material type, diameter, length, etc., installed at or around the same time) while there are often few identical within vertical asset categories (e.g., 2 or 3 pumps within a utility may be the same, while the rest are different sizes or types). For these reasons, as well as those listed below, the horizontal risk report is being prepared separately from the vertical risk report. It is relatively easy to visually inspect vertical assets because most often they are located above ground or able to be accessed/observed from ground level. Horizontal assets, on the other hand, can be very difficult to visually evaluate. In many cases horizontal assets are buried with limited access points, requiring some type of specialized electronic device (e.g., closed-circuit television (CCTV) camera) for inspection. Furthermore, operations and maintenance personnel often have greater knowledge of vertical assets because they interact with them on a more routine basis. This makes it easier to rate parameters related to asset management, including condition, useful life remaining, probability of failure (POF), and consequence of failure (COF). These assessments cannot generally be completed easily for individual horizontal assets. Operation and maintenance personnel do not typically have detailed information regarding the condition and performance of each piece of pipe or each manhole in the collection system. However, operation and maintenance personnel, as well as engineering personnel, may have a general knowledge of certain groups of assets or assets related to problem areas in the system. For example, clay pipes may outlive cast-iron pipes or pipes in a certain area under subject to certain conditions (e.g., closer to the coast) fail more often. Or pipes in certain areas may perform worse than other pipes in the system. Data regarding vertical assets is typically stored in a computer program such as a computerized maintenance management system (CMMS), an asset management system, a spreadsheet, or a database. Horizontal assets are often stored in a geographic information system (GIS) database of some type. This relates to the fact that horizontal assets are more spatially related than vertical assets. In the future, if and when WWD obtains a CMMS system, this system may interact with the GIS system in some way such that data on horizontal assets may be obtained through either the GIS or CMMS or both. Horizontal Asset Categories The horizontal asset categories were obtained from WWD’s GIS. The data in the GIS system was obtained from the best available resources. There was no other written or electronic data that were considered better sources of information on horizontal assets. The PG Team was given access to the Risk Assessment Report: Horizontal Assets 3 entire GIS map and associated data, and all available information was downloaded into an electronic spreadsheet. Based on review of that data, the types of assets (also referred to as classes of assets) in the GIS included the following: chimneys, discharges (i.e., outfall pipes/pipelines), easements, grease interceptors, mains, manholes, plants, pump stations, pumps, services, and valves. Each class of asset represented in the GIS, along with a description of the available data is listed in Table 1. The table also includes a description of data gaps and the need for further work regarding that type of asset. Table 1: WWD Horizontal Asset Classes Class of Asset Comments GIS Data Data Gaps / Further Analysis Needed Chimney There are 59 total assets of this type in the GIS database/inventory. Chimneys are no longer used and are not considered a separately managed asset from manholes. No further analysis required. Discharges There are 10 total assets included – 7 private gang cesspools, 2 active WWD outfalls, and 1 active discharge identified as unknown. Only date installed and location. No further analysis possible at this time due to lack of data. Given the 7 private discharges, there are only 3 that potentially need further analysis. However, there is extremely limited information on the outfalls in the database. Easements There are 460 easements in the GIS database. These easements may be on private or public land. WWD does not manage this type of asset per se; therefore, no further analysis is necessary for this report. Additionally, there is almost no information on which to base an analysis. Limited. No further analysis possible or needed at this time. However, as a separate activity, the WWD may wish to determine who is responsible for maintaining easements and whether all easements are properly recorded and up to date. Grease Interceptors There are 32 grease interceptors in the GIS database. The interceptors are not owned or maintained by the WWD. No analysis required. Mains After scrubbing and analyzing the existing data, it was determined there are 3,733 pipe segments in the GIS database. This report includes extensive analysis of the mains. Description and analysis included in this report. Data discussion and analysis included in this report. Risk Assessment Report: Horizontal Assets 4 Class of Asset Comments GIS Data Data Gaps / Further Analysis Needed Manholes There are 3,445 manholes included in the GIS database. The manholes are not generally managed separately from the pipe. WWD inspects manholes when the pipe is televised. The manholes were discussed with staff and there were no particular attributes that anyone thought would make one manhole higher in priority than another, other than being associated with a high- priority pipe segment. Asset ID, status, owner, date installed, type, top elevation, invert elevation, rehabbed (17 listed as “lined,” rest as “not rehabbed”), material (2 brick, 1 concrete, all others unknown), depth (68 unknown, the rest range from 2.39 to 25.8 feet). If manholes continue to be addressed as part of the pipe (integral to the pipe, no further analysis is required). If, however, there are attributes that would distinguish the priority of one manhole over another, and that data is available for analysis, the manholes can be analyzed as a separate component. Plants There are 9 plants listed in the GIS database. These plants were all analyzed during the Vertical Asset Risk Assessment. See Vertical Asset Report. All included in the Vertical Asset Risk Assessment. Pump Stations There are 23 assets listed in the GIS database. These pump stations were all analyzed during the Vertical Asset Risk Assessment. See the Vertical Asset Risk Assessment. All included in the Vertical Asset Risk Assessment. Pumps It is unclear what information is included here. There are 17 assets included in the GIS under this category. All pumps were included in the vertical asset analysis. See the Vertical Asset Risk Assessment. All included in the Vertical Asset Risk Assessment. Services There are 7,482 services listed in the GIS Database. This asset is one that WWD would like to do an analysis of, but there is insufficient information to do the analysis. Status, date connected, cleanout), account name, number and address. Further analysis is desired, but there is limited data about the services that are included. This is something that will have to be collected and updated over time. Some types of information that would be valuable include the GPS location of the cleanout, the material of the service line, and past problems with the service line. Valves There are 16 valves listed in the GIS database, of these 12 are listed as private ownership. Therefore, there are only 4 air relief valves listed as owned by the WWD. There is essentially no information available about the air relief valves. Status, type of valve, and invert elevation. If further analysis is required, field data collection would be required. Risk Assessment Report: Horizontal Assets 5 The horizontal asset data most relevant to this report are related to pipes, manholes, services, and discharges. However, at this time, there is only sufficient information to do a detailed analysis of pipe segments. Data exists for manholes; however, they are considered by WWD to be integrated into the pipe system and get managed accordingly. Significant data gaps exist for services and discharges. Further analysis could be conducted if additional information is collected, or, in the case of the manholes, personnel can provide some indication of how the existing data can be used to indicate the criticality of individual manholes. As noted above, several asset classes have been addressed in the Vertical Asset Risk Assessment, and the remainder have been excluded for various reasons (e.g., not managed by WWD). Wastewater Pipe Data Sources and Information There are two sets of available data that can potentially be used to perform an assessment of the individual pipe segments within the WWD system – the GIS system and the CCTV data. The best available data on individual pieces of pipe and manholes is the information that is produced from CCTV analysis. While this is the best available information, it does not mean that this data has been through a rigorous quality control process. Furthermore, the CCTV videos can be interpreted differently by different individuals so not all defects may be treated the same. There is no standard operating procedure for how the interpretations should be done, so the data is subject to differences. Nevertheless, at this point, this is the available data so it will be used for the analysis. In the future, more rigorous procedures can be adopted to improve the CCTV data quality. This CCTV data includes videos and, in some cases, hand written records. When the data is provided to the GIS personnel, this information is added to the defects layer. This level of data – CCTV information – is only available for a small percentage of the pipe – about 5.7% (see Table 2). Table 3 provides similar data, further broken down by diameter of pipe (CCTV data is discussed further in the Pipe Analysis Using CCTV Data). The other source of data is the general information contained in the GIS database. This data was downloaded from GIS into an Excel spreadsheet. Additional analysis was completed for both the spreadsheet data and using the spatial information in the GIS. This analysis is discussed in Pipe Analysis Using GIS Data. The quantity of CCTV data is too low to be statistically significant. Furthermore, the pipes selected for CCTV were not selected such that they would represent a large cross-section of the collection system. Rather, these pipes were selected based on areas that operators knew or thought to be of concern. The same pipes are often televised due to concerns related to defects or clogs; there is no systematic approach for televising the entire collection system. A true risk assessment using POF and COF scores for every pipe segment is not possible because there is such limited documented and representative data. In order to make best use of the information available in WWD’s GIS and from past CCTV efforts, the PG Team rated POF for those segments with existing CCTV data as well as implemented a process to prioritize segments in the entire collection system based on specific criteria defined by WWD. These efforts (described in the report below) should only be viewed as a starting point for risk assessment. Further data collection (extensive) and quality control is needed to perform a proper and complete risk assessment.

Therefore, the lengths on the table above will not add up to the total of 106.16. That total includes all pipe sizes, whether scoped or not. Pipe Analysis Using CCTV Data There were three basic sources of information for CCTV data: 1) paper records of CCTV work with some indication of start and stop manhole, 2) video recordings for most CCTV work, and 3) information from the defects layer of the GIS system that contains some information regarding defects observed through CCTV work. None of these three sources was comprehensive and it is unlikely, even collectively, that all three sources provide all of the information related to all of the CCTV work that has been done by WWD. For example, WWD has been inconsistent in getting all of the observed defects from the videos logged onto paper, and subsequently, into the GIS database. Another major data gap is the lack of information showing whether the defects were repaired. Almost all defects show up as “unresolved” in the GIS defect layer even though it is highly likely that at least Risk Assessment Report: Horizontal Assets 7 some of the defects have been resolved. In some cases, the same pipe was surveyed on different dates and defects that appeared in the earlier survey are not evident in the later survey. This result provides some evidence that the defect was probably resolved but the GIS does not reflect that. Discussions with operators also indicated that certain types of defects are typically fixed soon after discovery. Therefore, it is highly likely that some of the defects discovered during the CCTV work have been repaired in some way – whether a spot repair or partial pipe replacement – but there is insufficient data to determine which ones have or have not been addressed. The type of pipe defects that were noted on either the paper forms or the CCTV videos include the following: • Crack at joint: the pipe is cracked where two pipes connect • Crack: the pipe is cracked somewhere between connections with neighboring pieces of pipe • Infiltration/inflow (I/I): water can be seen flowing into the pipe through the walls of the pipe • Blockage: The flow is blocked with debris or fats, oils, and grease that prevents either all or most of the sewage flow • Deformed: The pipe is not round all the way around; it is deformed from its original shape to something else. • MSGPipe: MSG stands for missing pipe. Most likely the crown is missing from sewer gases eroding it away but it can be any missing piece of pipe where only the dirt that used to be around the pipe is acting as pipe. • Offset: The pipe is not aligned properly and one piece of pipe is off-set from the other so that there is not a smooth flow path between the neighboring pipes. • Point: A place in the sewer where a point repair has been made • Root Intrusion: Roots have infiltrated into the sewer. • Sag: The pipe is sagging in one section where that piece of pipe is lower than the ones before and after it. This creates low spots where debris can collect. • Undercut: The material supporting the sewer has been undercut and is no longer able to hold the sewer up properly or will not be in the future • Unknown: There is some type of defect in the pipe but it does not fit one of the other categories or it is not possible to identify what is causing the problem. This could be due to poor video quality. The National Association of Sewer Service Companies (NASSCO) has established procedures for assigning ratings to sewer pipe related to condition and risk assessment, based on observations made during CCTV activities. These procedures, or similar procedures, have not been employed by WWD. As a result, there is no data to support this type of analysis. Developing this level of detail and rating of the sewer pipes would require a significant televising and re-televising effort, which cannot be completed with resources allocated for this project. Instead, a simpler approach has been employed using the available data and knowledge of the WWD operators. The PG Team’s approach included the following steps: • Discussions were held with WWD staff to determine if any of the defects noted in GIS were considered higher priority than any others or were considered to have more of an impact on the overall integrity or functioning of the pipe. The three defects selected as higher priority were: crack at joint, crack, and I/I. These defects were given higher rating in our analysis. Risk Assessment Report: Horizontal Assets 8 • All available paper records of CCTV data were reviewed to determine which defects were noted during the CCTV work. These paper records were compared to the video footage to see if they matched up. • All available CCTV data was reviewed to determine if defects were noted during the survey. • All defects by pipe were noted on an Excel spreadsheet, including type of defect and position of defect along pipe (length from initial manhole). • The start and stop manhole IDs were noted for each pipe. These manhole IDs were used to determine a pipe asset ID using GIS. There is no easy way to relate pipe lengths to manholes with ID information provided, so a manual process was used. The process involved selecting the entry and exit manholes on the GIS map and determining which pipe was in-between. The pipe asset ID was then taken off the GIS map and entered into the spreadsheet. • The pipe type, size, and length of videoed pipe were noted whenever available on either the paper records or in text on the video. • In cases where some or all of this information was missing, the pipe asset ID (found as described above) was used to look up information in the database. The pipe type, diameter, or pipe length were gained in this manner when possible. In some cases, the data did not exist in either the spreadsheet or the video, and these pipes were marked “unknown” for those criteria. In cases where data existed in both places (GIS and video), spot checks were made of the two lengths to see how well they corresponded. In many cases, the distances were close. In others, they were different. The CCTV was generally used as more reliable data source given that the video may not have included the entire pipe segment, or the GIS may be incorrect for length. As an initial screening and prioritization of the televised pipe data, a ranking system was developed. Personnel at WWD were asked which defects were the most critical to the sewer condition and which were less critical. Based on those discussions, it was determined that the major defects were: crack at joint, crack, and Infiltration/Inflow. These defects were considered “major defects” and were given 5 points each, while other defects were considered to be “minor defects” and were given 1 point each. Table 4 describes the rating system. This rating system provides a starting point to rank sewers for future inspection and repair. It is a system that can be revised over time as WWD gains more experience with asset management and more knowledge about the sewer system. Table 4: Criteria for Probability of Failure for Wastewater Collection Pipes That Have Been Televised Description Number of Points Total Score Major defect: Crack at Joint 5 points per crack at joint 5 * Number of Cracks at Joint Major defect: Crack 5 points per crack 5 * Number of Cracks Major defect: I/I 5 points per I/I 5 * Number of I/I Minor Defects 1 point per defect identified 1 * Number of minor defects Each pipe segment that was Televised was assessed using the point totals in Table 4. Each major defect was given 5 points, each minor defect was given 1 point and the total number of points was calculated. The total scores ranged from a high of 121 to a low of 1. If all pipes were normalized together, the high scores would cause the vast majority of pipes to be a score of 1. This result does not help differentiate one pipe from another; rather it lumps a large number of pipes into the same category. To address this situation, the pipes were separated based on overall score first. Those pipes with a score 20 or greater Risk Assessment Report: Horizontal Assets 9 were considered high POF and those with scores of less than 20 would be medium and low POF. The high POF pipes were then normalized to a 1 to 10 scale. The medium and low POF pipes were then normalized, as a group, to a 1 to 10 scale. Those pipes that scored 10 to 4 POF, were considered medium POF and those less than 4, low POF. It should be noted that the POF scores for the high POF pipes should NOT be compared to those in the medium and low categories. The POF scores (1 to 10) indicate a probability of failure of the pipe segments, with higher scores indicating a greater risk of failure and lower scores indicating a lower risk of failure. The results of the analysis by pipe segment are contained in Appendix A, which has a table containing all pipe segments televised, their basin, location (generally indicated by street name), type and diameter, the number of defects observed and the normalized probability of failure (POF) score. The breakdown of the pipe segments based on POF is shown in Figure 1 below. Of the pipes ranked, 7% were high POF, 26% were medium POF, and the remaining 67% ranked low POF. A summary table and map are presented in Figure 2. The map shows locations of the 12 pipe segments with a high POF score. 7% 26% 67% Figure 1: Percentage of Main Segment by POF (based on CCTV data) High POF Medium POF Low POF Risk Assessment Report: Horizontal Assets 10 Figure 2: Map of High POF Pipe from CCTV Data Risk Assessment Report: Horizontal Assets 11 Pipe Analysis Using GIS Data The entire wastewater collection system consists of approximately 111 miles of pipe, separated into 7 basins on the east and west sides of the island. The pipe is separated in the GIS database by pipe segment. A pipe segment is defined as the length of pipe between two manholes. Therefore, the pipe segments are not all the same length. The number of pipe segments found in each basin is shown in Table 5; there are 3,733 pipe segments in the collection system. However, the Heeia and Kilohana systems are not owned or maintained by the County. For this reason, no further analysis is provided for these basins. Table 5: Number of Pipe Segments by Basin East of West Basin Number of Segments East Hilo 1552 East Kulaimano 183 East Papaikou-Paukaa 286 West Heeia 251 West Kaloko 4 West Kealakehe 1401 West Kilohana 56 Totals 3,733 Each segment is given an asset ID number. In general, these asset IDs are unique. However, there are some situations in which duplicate ID numbers have been used. For example, 90000 series numbers were used at one time to indicate proposed pipe and, in some cases, pipe not owned by COH (e.g., private ownership.) The initial data dump with all pipes of all ownership types and including proposed pipes included 120 duplicate IDs. After further analysis, removing all proposed or inactive pipes and removing all pipes that were not owned by COH, there were still 11 pipes with duplicate asset IDs. The duplicates are shown below: • Asset ID = 90007: 7 pipes listed as owned by the County with Active Status • Asset ID = 9677: 2 pipes listed as owned by the County with Active Status • Asset ID = 25335: 2 pipes listed as owned by the County with Active Status The pipe segments with duplicate IDs have been left in the database. Eventually, these pipe segments will need to be renamed with unique ID numbers, or if the information about the ownership and status is incorrect, they will need to be removed altogether. Method The PG Team used GIS data to help expand the risk assessment beyond what was possible through CCTV data alone. Given that the majority of pipes have not been inspected with CCTV, the only way to develop a more robust prioritization is to use existing information available in GIS or information that could be developed from manipulating GIS data. Discussions were also held with WWD staff to determine which factors most likely indicated potential problems in a pipe segment. Pipes with a greater likelihood of problems would be considered higher priority for further investigation using CCTV in the future. Alternatively, these pipes may require further analysis in terms of operations to see if they are causing more back-ups or overflows due to issues such as capacity, slope, etc. Risk Assessment Report: Horizontal Assets 12 The factors identified by WWD staff as potential indicators that impact POF include: pipe material, depth of bury, diameter, installation date, and proximity to the shore while also at a relatively low surface elevation. Appendix B contains a description of how the factors were applied in the analysis. Some factors, particularly the proximity to shore, required an extensive process to determine whether the pipe segments were within “the buffer zone.” The buffer zone was the terminology used to indicate if the pipe was within 600 feet of the shoreline and within 20 feet of sea level elevation. Table 6 indicates the various factors that were used and how the points were applied. The factors were not given equal weight. The highest weight was given to concrete pipes in the buffer zone. This ranking was chosen in consultation with WWD staff. Based on their knowledge of pipes and how they perform throughout the system, pipes in the buffer zone were considered the most problematic because these pipes have the potential to be impacted by sea water, either sometimes or all the time. As sea level rises, this factor may become even more important. While high weight (5 points) was applied to any pipe in the buffer zone, a higher weight was given to the concrete pipes (5 extra points or 10 points total) based on discussions with WWD staff. While the initial assessment gave the highest ranking to pipes in the buffer zone, if future analysis or CCTV work determines that being close to the ocean has less impact than WWD initially thought, the weighting can be changed in the future to reflect this. Table 6: Criteria for Probability of Failure for Prioritization of Wastewater Collection Pipes Item Category for Points Number of Points Comments Pipe Within the Buffer Zone Concrete Pipe within the Buffer Zone 10 The pipe is within 600 feet of the ocean in areas where the elevation is 20 feet or less from sea level Any Other Pipe Type Within the Buffer Zone 5 Pipe Outside the Buffer Zone 0 Pipe Type VCP 5 Unknown pipe type was given an average rating of 3. Cast Iron 4 Concrete or Unknown 3 PVC 2 Any Other Pipe Type 1 Depth of Bury Less Than 5 Feet 2 Pipe that was more shallowly buried was given a slightly higher rating given the potential for breaks to be slightly higher due to root intrusion, traffic, or potentially mechanical damage due to excavation. Greater Than 10 Feet 1 Unknown 1 Between 5 Feet and 10 Feet 0 Diameter 8” Diameter or Less 2 Unknown was given a mid- range number of 1 for this factor Unknown 1 Greater than 8” 0 Time Period of Pipe Installation Installed in 1950s, 1960s or 1970s 5 In discussions with WWD personnel, pipe from the 50s, 60s, and 70s, has been performing more poorly than other ages of installation Unknown date 3 Any other date of installation 0 Risk Assessment Report: Horizontal Assets 13 In cases where the pipe characteristics were unknown, a higher moderate number of points was assigned for that characteristic. For example, if the pipe diameter was unknown, it was given 1 point, while if it was 8 inches or below it was given 2 points or 0 points if it was above 8 inches. The unknowns were given higher weight than the lowest score because the fact that the information is unknown poses some problems for the system. For each pipe segment, the available data was assessed to determine which points should be applied. All points were added up to get a total score and then the highest total was used to normalize the scores from a 1 to 10 scale. The scores were normalized by Basin because the information will have greater meaning if pipes are compared to those in similar circumstances. The total score ranges, prior to normalization are shown in the table below. In two cases, Kaloko and Kilohana, all of the pipes had exactly the same characteristics (based on the chosen parameters) so all pipes scored the same number (10) on the normalization process. Further investigation may be necessary if there is a need to further differentiate this pipe. Because there are so few pipes in Kaloko it is probably not necessary. There are 56 segments in Kilohana so additional review may be warranted. Table 7: Total Scores and Normalized Score Ranges by Basin East or West Basin ID Total Score Range Normalized Score East Hilo 1-15 1-10 East Kulaimano 1-11 1-10 East Papaikou-Paukaa 1-14 1-10 West Kaloko 3 10 West Kealakehe 1-21 1-10 In general, the pipes on the west side of the island had slightly higher scores than the east side. Because pipes in different basins are subject to slightly different conditions than pipes in other basins, the pipes were ranked based on the basin. Tables 8 through 12 show the number of pipe segments by normalized score for each basin. Scores from 10 to 8 were considered high priority, scores from 7 to 4 were considered medium priority, and scores 3 or less were considered low priority. The tables are color-coded by priority (green = low, yellow = medium, red = high). Table 13 shows the number of segments overall by priority score. Appendix C contains maps of the pipes with medium to high priority by basin and Appendix D contains a listing of every pipe segment in the system as well as the factors that were used to develop the priority ranking.

This approach is described in Selection of Pipes for CCTV, below. Comparison of CCTV Data to Pipe Prioritization Although there is limited data from the CCTV work, the PG Team was able to perform some comparisons between pipes that were showing signs of distress (high numbers of defects) and how that same pipe ranked in the overall prioritization process utilizing GIS data. Table 16 compares high POF score pipe from the CCTV analysis with its score in the overall pipe prioritization. Table 17 compares medium and low POF score pipes to the overall pipe prioritization. The two groups were split because, as was discussed above, the two groups were normalized separately.

The lower POF score pipe from CCTV analysis is showing up as higher priority and the higher POF score pipe is generally not showing up as high priority. There are two potential options: 1) continue with the prioritization as already conducted and do some random sampling of the pipe using CCTV to determine if there is sufficient correlation, or 2) revise the prioritization process and compare again with the CCTV data that already exists. Recommendations Based on the analyses described above, the PG Team offers the following recommendations for implementing better horizontal asset analysis processes in the future. 1. Implement a more robust strategy for CCTV prioritization: The most important recommendation is to implement a more robust process for selecting pipes to CCTV than what is used currently. Some of the pipes currently being televised more often do seem to have a considerable number of defects; however, others seem fine. WWD should review the factors selected for CCTV prioritization to determine if there are any factors that should be added, removed, or weighted differently. Following review, the analysis can be repeated. Implementing a more strategic prioritization approach will help assure that WWD is getting the most value out of its CCTV efforts. WWD should review the Selection of Pipes for CCTV section (below) for potential options to improve CCTV prioritization. The main issue is to use the CCTV as a tool to evaluate pipe condition and potential for failure and to ensure that the resources committed to CCTV are being well spent. 2. Separate CCTV prioritization and cleaning prioritization processes: It is important to distinguish between a pipe that needs to be cleaned often and one that needs to be televised often. Cleaning and CCTV activities should be separated into two functions. When pipes need to be cleaned often, they should be put into a rotation for cleaning, and should be televised only when other factors Risk Assessment Report: Horizontal Assets 19 indicate. CCTV should be used when detailed information about pipe status and condition is required or desired. Efficiencies should be gained by separating the two processes. 3. Close data gaps for manholes, discharges, services, and valves: There is insufficient data to fully assess POF and COF for horizontal assets, other than pipe. The assets of particular concern are manholes, discharges, services, and valves (those located in the field, not in treatment plants or pump stations). Basic data is missing for most of these assets and there is no useful operational data documented in an easily accessible manner for any of them. Going forward, WWD should take every opportunity to add basic characterization as well as operational data to the GIS database as described below. o For basic data: Any time field crews are working with horizontal assets, basic data should be collected for each asset and that data should be provided back to the GIS personnel. This data collection process can be completed using hand-held devices, or it can be written on paper and provided to the GIS personnel. In either case, a formalized procedure should be established. In particular, there is considerable missing data on discharges, services, and valves, and some missing data on manholes. Once this type of data is collected, an analysis of these types of horizontal assets can be performed. Developing a standard operating procedure (SOP) for this type of data collection, including what types of data to collect and how to collect it, should be considered. o Operational data regarding problems that have been experienced in the field, as well as the steps taken to correct the concerns, should be added to the database whenever possible. As an example, if a service has had issues and actions had to be taken to correct the problem, there needs to be a way to tie that information to the asset. When collecting data of all types, it is important to assure that the data is tied to the asset ID. 4. Implement field verification of GIS data: The GIS system is only as accurate as the information it was based on. Initially, this level of accuracy is the same as the accuracy of the sources, such as design drawings, as-builts and people’s memories of asset locations, which is going to be limited. Over time, the accuracy can be increased when field personnel provide information back to the GIS personnel regarding any inaccuracies. The inaccuracies may relate to size, material, location, length, slope, or depth, and may be identified through CCTV work, sewer cleaning, or repair work. It is not uncommon to have some wrong information in the GIS database initially, but the situation can only improve with the implementation of a robust process of field data verification. This type of process will require standard operating procedures for how field personnel should report data and an approach to hold individuals accountable for sharing the information between the field and GIS personnel. 5. Make sure operational data is available to inform prioritization: Operational data regarding pipes is very helpful in asset management analyses. For example, information regarding pipe segments that experience frequent overflows or clogs can inform prioritization efforts. Spills and overflows are required to be reported but other problems are not, such as clogs. Some of this information is contained in the spills and bypass layer in GIS, however, some of the data is missing. Similar to recommendation number 4, there should be standard operating procedures for ensuring that spills, overflows, clogs, areas cleaned and other operational data regarding sewers is conveyed in a timely Risk Assessment Report: Horizontal Assets 20 manner to the GIS personnel. There should be some type of accountability to ensure that the information is conveyed and that it is added to the system. 6. Create a CCTV data collection SOP: The CCTV process is an excellent time to learn information about the wastewater collection system. Sometimes, this information is collected either in paper or on the video, by adding text and sometimes it is not effectively captured. In addition, sometimes the information is provided to the GIS system, but it isn’t always provided. An SOP should be written to require specific and consistent data capture during the CCTV process. The SOP should include a description of the type of information to collect, when to collect it, how to collect it, and how to provide it to the GIS personnel. At a minimum, it would be helpful to have, the following: pipe asset ID, start and stop manhole with ID, diameter, pipe type, length of pipe videoed and length of pipe segment if entire pipe is completed, and defects (type and location). 7. Verify the status of all defects included in GIS: For all work completed on pipes, such as the repair of the cracks, information should be provided to the GIS personnel in a readily usable format so that the issue can be changed to “resolved.” Currently almost every defect in the system is labeled as “unresolved” even though there is evidence to suggest that it has been resolved (e.g., evidence from later CCTV video and discussions with field personnel.) Keeping up with the resolution of defects would allow the defects layer to be of greater value in future analysis of horizontal pipe assets. 8. Develop a condition rating process for evaluating the condition of sewer pipe using the CCTV data: There are already established processes that could be used (e.g., NASSCO) or WWD could develop one of their own. WWD may wish to determine what processes are used by other counties in Hawai’i, if any, to see if one of those approaches might work. If a process from another county is used, it would give WWD peers to learn from as well as pose questions to if problems arise. In any case, the CCTV data can be more meaningful if it is used to develop a pipe condition rating. This rating should be added to the GIS. 9. Properly implementing a rating system for pipe using CCTV data is likely to require staff training. At a minimum, line maintenance personnel from both sides of the island should be trained. Additionally, supervisory staff may also benefit from attending this type of training. 10. Include depth of bury in GIS for pipe segments: The depth of bury should be included in GIS if it is a key criterion for identifying pipe segment POF. This data can be developed from manhole depths but not easily. If manholes are tied to a specific pipe, the depth field can be populated. 11. Add risk or priority data to GIS: Eventually, the risk or priority of the pipes needs to be added to the GIS database. The prioritization in this report is too preliminary to include. After a prioritization process is finalized and verified using CCTV, it can be added to the pipe assets using the asset ID. Pipes can then be color-coded based on priority to show that information visually. 12. Improve GIS symbology: The GIS symbology could be improved. There are some industry standard symbols that WWD might wish to use to make it easier for new personnel or contractors to work with the GIS maps and associated data. Risk Assessment Report: Horizontal Assets 21 13. GIS could include different layers for different pipe types: The sewer mains layer may benefit from being split into different layers. The pipe could be placed in different layers that can be turned on or off as desired based on the user’s needs. The pipe types are: force, gravity, outfall, syphon, etc. If each of these was on a different layer, it would be easier to find certain types of pipe in the field as only those types would need to be displayed on the map. This can make easier for operators to target specific locations for specific maintenance activities. 14. Remove duplicate pipe IDs from GIS: As discussed in the report, there are duplicate asset ID numbers for some pipes, particularly in the Hilo Basin. Specifically, the duplicate pipe IDs were observed as follows: In Hilo: o Asset ID 90003: 45 pipes, proposed o Asset ID 90004: 64 pipes, proposed o Asset ID 90011: 7 pipes, active, and owned by WWD o Asset ID 9677: 2 pipes, active, but appear to be the same pipe entered twice o Asset ID 25335: 2 pipes, active, but appear to be the same pipe entered twice In Kealakehe: o Asset ID 90007: 9 pipes, active, but under private ownership o Asset ID 90009: 4 pipes, proposed In all, 133 pipe segments show up in the GIS data base with duplicate asset IDs. The duplicate IDs related to proposed pipe segments and private ownership can be eliminated by the filters that are normally put on the GIS system to keep field personnel from seeing these pipes. For the most part, they do not need to access the information. It is recommended that even these proposed pipes be given unique identifiers, but it is not absolutely necessary. For the pipes that are not proposed or under private ownership, the duplicate IDs should be eliminated. It is critical that all assets have unique ID numbers as it is the only way to distinguish one asset from another and is the key means of tying information together from one source to another. 15. For pipe that is proposed, an SOP should be established to describe how these pipes are to be entered, what the ID number will be, and how they will be distinguished from pipe that is active and installed in the system. The establishment of an SOP would help ensure that the procedure remains consistent even if there is staff turnover in the future. Selection of Pipes for CCTV The analysis described in this report should be used as a starting point for WWD to establish a more robust and proactive CCTV program. The success of a CCTV program is closely tied to the effectiveness Risk Assessment Report: Horizontal Assets 22 of the strategy used to select and prioritize pipe for televising. There are different ways pipes can be selected, and each method has its merits and shortcomings. Some useful approaches for implementing a successful CCTV program are included below: 1. Select a statistical sampling of the total pipes in the network: In this approach the pipe in the collection system is categorized based on pipe type, size, location, age, condition, and any other descriptive factors to determine pipe “cohorts.” A pipe cohort would be a set of pipes of similar characteristics. For example, all the 6-inch clay pipe in the Hilo basin of the age range 50 to 70 years old. The amount of pipe in each cohort would be identified by either pipe segment or pipe length. Then pipe can be selected at random from each cohort for CCTV analysis. Based on the results of the CCTV work, the condition of each sewer pipe televised would be assessed. Because this data would be statistically significant, the condition of the televised pipe could be used to provide an overall evaluation of the entire collection system. The benefit of this approach is that it would be possible to make some judgements about the overall system’s condition and to use this information in developing a long-term pipe replacement program. The challenges with this approach include the need to categorize each pipe cohort. A fair amount of work would be required to complete that analysis. Pipes would then need to be selected at random in a quantity sufficient to have a statistical sampling. This work would need to be in addition to any CCTV work that is done on pipes with known problems so resources may be insufficient to complete the necessary work. 2. CCTV all the pipe in the system on a rotating basis: Based on the 110.8 miles of pipe in the WWD collection system, for the whole system to be reviewed even on a 10-year basis, 11 miles of pipe would have to be investigated every year. Given that only slightly more than 6 miles of pipe have been televised over the past several years, this pace of CCTV seems unrealistic. If half as much pipe was completed (5.5 miles per year), it would take 20 years to view every pipe. That schedule may not be fast enough to make the collection of the data useful. The benefit of this approach is that all the pipe would be viewed and the entire system’s condition could be assessed with actual data from each pipe. Furthermore, the GIS system could be verified and corrected as the CCTV work was being completed. The challenges with this approach are the need for a much faster pace of work than is currently being achieved and the need for significant additional resources. It is hard to conclude that the money, personnel, equipment, and/or contracts that would be required to complete the work are the best expenditure of resources for the utility. The condition of vertical assets in some of the treatment plants and pump stations, as well as other resource needs, such as future regulatory compliance would be considered higher priorities than CCTV. 3. Use a prioritization approach of pipe to determine which pipes require the CCTV work the most: A prioritization approach should consider all that is readily known about the system and pipes. At this point, that information includes what is in the GIS database, which is limiting in many cases. Risk Assessment Report: Horizontal Assets 23 The benefit of this approach is that pipe would be televised based on thoughtful prioritization, completing those segments with a higher POF and/or COF first. The challenges of this approach are the establishment of the prioritization metrics. The approach outlined in this report provide a starting point, but would need further refinement before adoption and full implementation. The current information – the GIS database – does not include sufficient operational data to improve the prioritization process. In the future, this method would be greatly enhanced by combining operational data, operational experience, and basic attribute information from the GIS. 4. Select pipes for CCTV based only on past experience: This is the approach that is currently employed. There are some merits to this, but there are also some shortcomings. The positive of this approach is to directly tie operator experience to the CCTV process. The challenges of this approach are that experience is not always the best judge overall.

The GIS files were obtained by the PG Team and the underlying data behind the GIS data layers was downloaded to an Excel spreadsheet. The intent was to use the downloaded data to determine a prioritization and criticality of wastewater pipes, and determine the following aspects of the pipes: • Pipe materials (pipe type) • Pipe size • Pipe age/date of installation • Distance from ocean shoreline (termed “within the Buffer Zone” and defined as within 600 feet of the shoreline when it was also within 20 feet of sea level) • Depth of bury (less than 5 feet, greater than 10 feet) These factors were applied to all pipes within the wastewater collection system. While some of the factors were easy to analyze using the Excel data generated from GIS (pipe type, size, and age of installation), two factors required a much more involved analysis: within the buffer zone and depth of bury. Neither of these attributes was directly in the database. The process used to gain this data is presented below. Within the “buffer zone” (distance from ocean shoreline and elevation within 20 feet of sea level): To find out whether the pipe segment was within the buffer zone, a polyline representing the shoreline was generated using the DEM (Digital Elevation Model) of the island. From this polyline, a duplicate was created and offset by 600 feet inland. Next a contour line at an elevation of 20 feet was generated from the same DEM. This contour line allowed for the exclusion of areas with elevations greater than 20 feet from the 600-foot shoreline buffer. The resulting buffer was used to capture all areas within 600 feet of the shore and at an elevation of 20 feet or less. Once this polyline was created, all the pipes within this buffer zone could be identified. All of these pipes were identified, and the data was captured within an Excel data table. Depth of bury: The depth of bury for the wastewater pipes was not available directly as an attribute in the database. The closest associated data was the depth of manholes. Unfortunately, this data could not be used directly because the manholes were not associated directly with the pipe segment ID numbers. Therefore, another means of determining depth of bury had to be employed. The manhole depths that were less than 5 or greater than 10 feet deep were highlighted on the map. Then the pipe segments that were between the manholes were highlighted manually. The pipe IDs were then associated with the manholes to gain a depth for the pipe IDs. This was a lengthy process to gain all the main depths that were less than 5 feet or greater than 10 feet. Analysis of remaining factors: For the analysis of the remaining factors, the associated Excel data tables were manipulated and sorted in various ways to give the pipes the appropriate scores.
