Executive Summary
Background
The Department of Water Supply (DWS) is asemi-autonomous agency of the County of Hawaii
that operates by rules and regulations adopted by the Water Board. The Department operates
and maintains its water systems with revenues generated solely through billings for water service.
The primary function of the Department is to provide safe drinking water through its 23 individual
water systems distributed around the island. Attachment 1.1.
DWS continuously strives to provide dependable, uninterrupted, high quality, potable water at a
reasonable cost in compliance with the Safe Drinking Water Act. DWS services nine districts using
four baseyards located in Hilo, Kona, Waimea, and Kau.
DWS can draw on its 23 water systems to support any of its out-of-service deepwells.
The Office of the County Auditor has completed a follow-up engagement with the County of
Hawai`i's Department of Water Supply Contingency Plans. We initiated the audit on request of
the Hawaii County Council (Resolution 287-17) and numerous constituent concerns regarding
repair delays and water restrictions for the North Kona areas.
As required by federal law, DWS developed the Continuity of Operations Plan (COOP) (August
2010), which addressed operational procedures for disaster events. DWS also developed three
contingency plans in 2017 when four wells became inoperable. These contingency plans
included:
• Kona Operations Initial Plan
• North Kona Response and Responsibilities
• North Kona Operations Emergency Action Plan
The prior audit found gaps in DWS' COOP and three contingency plans. Specifically, contingency
plans should contain sufficient detail including prioritizing and clearly documenting emergency
procedures for all districts, three types of water usage restrictions to address water shortages,
clearly documenting communication procedures. In addition, DWS should list complete vendor
names and/or contact information that provide an essential function in their COOP.
As of September 2022, DWS confirmed 12 of the 14 deepwells in North Kona are operable, with
the exception of:
• Wai'aha Deepwell
o Pending negotiations over incomplete repair contract (Job No. 2016-1056)
• Makalei Estates Deepwell
o Awaiting developer redesign and construction of pump and motor (warranty issue)
Executive Summary 1
In this follow-up, we tested three recommendations to determine if DWS implemented our
contingency plan recommendations. We determined two recommendations were implemented
and one was resolved. We found:
Status of Recommendations Status
Develop and Implement a Complete Contingency and Communication
Plan by District
1. We recommended DWS develop a written contingency plan by district to Resolved
address emergency situations to mitigate potential impact on any
community. Or, at a minimum, include contingency plans that address
important risk scenarios into their Continuity of Operations Plan (COOP).
2. We further recommended DWS develop and implement a communications Implemented
plan to notify the public, administration, stakeholders, and all governmental
agencies that rely on information that may affect them or a community.
The plan should include but not limited to timely notices and updated status
of water events and holding community public meetings timely.
Update Continuity of Operations Plan (COOP)
3. We recommended DWS update their Continuity of Operations Plan (COOP) Implemented
to include essential vendor contract information to ensure that quick
reference information is accessible and available during emergencies.
Department Actions
Develop and Implement a Complete Contingency and Communication Plan by District
1. Completed Emergency Response Plan for seven water systems (Hilo, N. Kohala, N. Kona,
Olaa-Mountain View, South Kohala, South Kona, and Haina) identifying threat scenarios.
Completed Risk and Resiliency Assessment to help identify risks to further strengthen water
systems resiliency.
Plan to update continuity and contingency plans accordingly.
2. Developed and implemented communication plans and workflows for emergencies and non -
emergencies.
Update Continuity of Operations Plan (COOP)
3. Added contact information for essential vendors to 2020 Continuity of Operations Plan
(COOP). Approved sole source vendor for specialized water quality testing supplies.
Plan to review and update vendor contact information on a routine basis to keep current.
2 Executive Summary
History and Repair Status of North Kona Deepwells
Since January 2017, up to five of DWS' deepwells were intermittently in and out of service,
restricting water service to residents, businesses, and the public throughout North Kona. In
response, DWS provided the public with a history and repair status for five deepwells located in
North Kona: Honokohau, Hualalai, Keopu, Palani, and Wai`aha. Attachments 1.2 — 1.6a.
In January 2018, DWS reported the schedule for Wai`aha Deepwell repair was unknown.
Attachment 1.6b.
In June 2022, DWS reported 25% mandatory water restriction measures were needed due to the
failure of Hualalai Deepwell and approved the expedited purchase of replacement parts in efforts
to return Hualalai Deepwell back to service. DWS stressed that water quality was not threatened
by the loss of the well. Attachment 1.7.
Subsequently in July 2022, DWS reported interim repairs were made to the Kalaoa Deepwell,
downgrading North Kona areas to 10% voluntary water conservation. DWS said they are
confident that the water needs of the community will be met with the voluntary conservation in
effect and will continue to monitor the water system and adjust as necessary. Attachment 1.8.
Conclusion
Contingency and continuity plans are similar: they both require specific procedures in instances
where things go wrong to allow for continuing operations. A continuity plan is a broader plan that
includes steps on the prevention and recovery of operations in the event of a disaster. Whereas
a contingency plan is a vital part of the continuity plan that helps organizational leaders prepare
for all kinds of worst-case scenarios. In other words, contingency plans cover in -the -moment
procedures in an emergency while a continuity plan covers how an organization will recover to
normal operations.
Best practices say that contingency plans should address specific criteria for the initiation and
termination of water shortage stages, procedures for notification and education of the public, and
procedures for monitoring the situation during water shortage stages.
We commend the Department of Water Supply for their efforts to improve contingency plans and
providing water to customers during a disruption of deepwell operations. To further strengthen
internal controls over contingency plans, we've identified the following opportunities:
DWS should:
• Review and update written plans accordingly
• Consolidate applicable guidance
• Make plans accessible to appropriate DWS staff
• Re -certify Continuity of Operations Plan annually

Introduction
Objective
Did the Department of Water Supply implement the 2020 contingency plan audit
recommendations?
Scope
The prior audit evaluated contingency and continuity plans from October 2017 to August 2019.
The follow-up evaluated contingency and continuity plans from April 2022 to September 2022.
This follow-up audit was limited to reviewing and reporting on the implementation of the
recommendations. We did not consider new or previous issues that did not relate to our original
recommendations.
Methodology
To verify the Department of Water Supply implemented the 2020 contingency plans
recommendations, we:
• Corroborated information with appropriate staff to follow-up on the responses to audit
recommendations

Chapter 2
Status of Recommendations
Develop and Implement a Complete Contingency and Communication
Plan by District
Condition and Cause
DWS did not have formalized emergency contingency plans for all districts. Subsequently, three
contingency plans were developed in 2017 when four deepwells became inoperable. However,
these plans only applied to the North Kona areas or one district.
Effect of the Condition
The lack of detailed procedures and clear guidance increases difficulty managing water systems.
Recommendation 1
"We recommend the Department of Water Supply develop a written contingency plan by district
to address emergency situations to mitigate potential impact on any community. Or, at a minimum,
include contingency plan that address important risk scenarios into their existing Continuity of
Operations Plans."
Department Action
• As required by the American Water Infrastructure Act (AWIA) and Federal Emergency
Management Agency
o Completed Emergency Response Plan for seven water systems (Hilo, N. Kohala,
N. Kona, Olaa-Mountain View, South Kohala, South Kona, and Haina) identifying
threat scenarios serving these communities
o Completed Risk and Resiliency Assessment and Preparedness Assessment
Technical Memorandum for seven water systems to further strengthen water
systems resiliency
• Plan to update contingency plans accordingly
• Updated Continuity of Operations Plan (COOP)
o Implemented pandemic response
o Distributed COOP to Civil Defense, Police, Fire, and the Department of Public
Works
• Clarified smaller public water systems (PWS), such as DWS, used "district -level"
contingency plans, that are general in nature to allow flexibility and to let staff determine
the most prudent and appropriate response for an event
o Adopted best practice by the PWS which is regulated by the State of Hawaii,
Department of Health, Safe Drinking Water Branch
Status of Recommendations 7
• Developed spare pump and motor priority list program
o Having spare pumps and motors on -island saves time and prevents extended
delays in returning deepwells to service
o Procured pumps and motors
• Implemented recommendations from Water Board's Permitted Interaction Group (PIG) to
ensure resilience of our water systems and to improve operations
• Worked with Civil Defense to update the County's Hazard Mitigation Plan
Audit Activity
To verify status, we reviewed, corroborated sufficient and appropriate evidence, and found:
• DWS' 2017 contingency plans have not been updated in the last five years nor address
emergency situations to mitigate potential impact for nine districts
• DWS' 2020 Continuity of Operations Plan was updated once in the last ten years, does
not address important risk scenarios for nine districts, and was not re -certified annually
• Review of Emergency Response Plan (ERP) for seven water systems found no exceptions
• Review of Risk and Resiliency Assessment (RRA) Report and Preparedness Assessment
Technical Memorandum for seven water systems found no exceptions
Although we noted contingency plans and COOP could be further developed to address risk
scenarios, we determined this recommendation resolved because only seven water systems
require an RRA and ERP to be completed by AWIA compliance requirement
• Review of public water systems (PWS) found DWS belongs to community water system
(CWS): A public water system that supplies water to the same population year-round and
found there are no Federal, State, or local statues that exempts municipalities with smaller
water systems from not having completed, detailed, and written contingency plans
• Review of Notice of Awards found no spare pumps and motors were ordered for three out -
of -service North Kona Deepwells: Honokohau, Palani, and Wai'aha
Although DWS developed a spare pump and motor priority list program, some spares are
at risk of losing warranty if the unit sits too long
In June 2022, DWS approved expediated purchase of replacement parts in efforts to
return Hualalai Deepwell back to service
Four deepwells awaiting bid submittals with one-year manufacture warranty:
o Halekii Deepwell power cable
o Keopu #1 Deepwell pump, motor, and power cable
o Parker Ranch Deepwell pump, motor, power cable, and shroud assembly
o Waimea Deepwell pump and motor
Halekii Deepwell pump and motor picked up for refurbishment
8 Status of Recommendations
As of September 2022, DWS confirmed 12 of the 14 deepwells in North Kona are
operable, with the exception of:
o Wai'aha Deepwell
■ Pending negotiations over incomplete repair contract (Job No. 2016-1056)
o Makalei Estates Deepwell
■ Awaiting developer redesign and construction of pump and motor (warranty
issue)
• Review of Water Board Minutes and Permitted Interaction Group (North Kona) —
Strategies and Actions Moving Forward found standardized materials, pumps, and motors
and alignment survey were completed to ensure proper size equipment were being
installed
• Review of County's 2015 Hazardous Mitigation Plan (HMP) found although water wells
are categorized as a critical lifeline facility to the County, one of the County's HMP goals
is to ensure that lifeline infrastructures can withstand hazardous events or contingency
plans to expedite recovery was not in place. Currently, there is no contingency plan to
provide water during a disruption of deepwell operations for nine districts
To further strengthen internal controls over contingency plans, DWS should:
• Review and update written plans accordingly
• Consolidate applicable guidance
• Make plans accessible to appropriate DWS staff
• Re -certify Continuity of Operations Plan annually
Status: Resolved
Status of Recommendations 9
Condition and Cause
DWS did not have formalized communication plans and procedures to effectively notify the public
to reduce water usage during emergency and non -emergency events.
Effect of the Condition
Public confidence declines without reliable communications during immediate, impending, or
extensive disruptions of water service.
Recommendation 2
"We further recommend the Department of Water Supply develop and implement a
communications plan to notify the public, administration, stakeholders, and all governmental
agencies that rely on information that may affect them or a community. The plan should include
but not limited to timely notices and updates status of water events and holding community public
meetings timely. "
Department Action
• Developed and implemented communication plans and workflows for:
o Emergencies
o Fire hydrant flow tests
o Scheduled water shutoff
o Water conservation/restriction
o Water main break
• Provided notices by:
o Radio
o Social media
o Email
o DWS website
o Hand -carry
o Civil Defense alerts
o Phone outreach
• Ensured continuity of messaging through DWS' Communications Branch
• Plan to update communications plan accordingly
Audit Activity
To verify status, we reviewed guidelines for small water systems, drought triggers, water storage
information charts, communication plans, flowcharts, workflows, voluntary and mandatory water
restriction notices, and found no exceptions. We also reviewed Water Board Minutes, bulletin
boards, social media, DWS website and found various forms of media were used to notify the public.
To further strengthen the communication plan, DWS should consolidate written guidance such as
drought triggers and three stages of water shortage conservation into their communication plan.
Status: Implemented
10 Status of Recommendations
Update Continuity of Operations Plan (COOP)
Condition and Cause
DWS did not document critical vendor contact information that performs an essential function in
2010 Continuity of Operations Plan.
Effect of the Condition
It is difficult for DWS staff to respond during emergencies with incomplete vendor contact
information.
Recommendation 3
"We recommend the Department of Water Supply update their Continuity of Operations Plan
(COOP) to include essential vendor contact information to ensure that quick reference information
is accessible and available during emergencies."
Department Action
• Added contact information for essential vendors to 2020 COOP
• Plan to review and update vendor contact information on a routine basis to keep current
Audit Activity
To verify status, we compared 2010 COOP to 2020 COOP Table 10 Critical Vendors, sole source
manufacturer letter, approved Notice and Request for Sole Source for specialized water quality
testing supplies, and found no exceptions.
Status: Implemented

Fraud, Waste, and Abuse
As a practice, we remain mindful and document instances of fraud, waste, and abuse.
Management did not report actual, alleged, or suspected fraud, waste, abuse; pending
investigations or ongoing investigations that might impact the results of the audit. We did not
identify specific issues during the engagement.
Fraud, Waste, and Abuse 12
Conclusion
The primary function of DWS is to provide safe drinking water service through its 23 individual
water systems distributed throughout the island. The Department of Water Supply continuously
strives to provide dependable, uninterrupted, high quality, potable water at a reasonable cost in
compliance with the Safe Drinking Water Act.
Contingency and continuity plans are similar: they both require specific procedures in instances
where things go wrong to allow for continuing operations. A continuity plan is a broader plan that
includes steps on the prevention and recovery of operations in the event of a disaster. Whereas
a contingency plan is a vital part of the continuity plan that helps organizational leaders prepare
for worst-case scenarios. In other words, contingency plans cover in -the -moment procedures in
an emergency while a continuity plan covers how an organization will get up and running again.
Best practices say that contingency plans should address specific criteria for the initiation and
termination of water shortage stages, procedures for notification and education of the public, and
procedures for monitoring the situation during water shortage stages.
We commend the Department of Water Supply for their efforts to improve contingency plans to
provide water to customers during a disruption of deepwell operations. To further strengthen
internal controls over contingency plans, we've identified some opportunities:
DWS should:
• Review and update written plans accordingly
• Consolidate applicable plans
• Make plans accessible to appropriate DWS staff
• Re -certify Continuity of Operations Plan annually

WAI'AHA DEEPWELL HISTORY AND REPAIR STATUS INFORMATION SHEET.
Information Sheet.
Overview,
Wai'aha Deepwell consists of a pump and motor which can produce approximately 1,400 gallons per minute. The pumping unit
is housed in a 20” well casing, which is approximately 1,754 feet deep. The pump bowl diameter is 11-1/8” and the pump is
approximately 17 feet long. The motor is a 4-Pole, 700 horsepower, 4,160- volt submersible motor. The motor diameter is 11”
and it is approximately 17 feet long.
Prior History,
Designed and built in June 2006, Wai'aha Deepwell has undergone repair one (1) time prior to this current repair.
Current Repair Status,
Wai'aha Deepwell is currently undergoing repair. Contractor for this repair is Derrick’s Drilling and Pump Services, LLC. Repairs
include the replacement of the existing deepwell submersible pump and motor, power cable, column pipe, column couplings, and all
appurtenant materials, such as cable guards and strapping; appurtenant electrical work; and chlorination and testing of the well and
pumping assembly. Pump and motor were installed as of July 26, 2017. Upon startup on July 27, 2017 the motor tripped on over
current condition. Trouble-shooting indicated a problem “down-hole” so the contractor proceeded with extracting all of the column
pipes, pump and motor. On July 29, 2017, during extraction of the pump and motor, there was a failure in the lifting cable resulting in
the pump, motor, most of the column pipe, and the power cable falling into the well. The contractor is working to remove the pump
and motor from the well. If removal is successful, the well will need to be inspected for any damages. The pump, motor, column pipe,
and power cable will need to be replaced to prevent an unknown weakened component causing a failure in the future. At this time, the
schedule for this well repair is unknown.

NEWS RELEASE
Water Restriction Notice Issued for North Kona.
Effective immediately, the Department of Water Supply (DWS), County of Hawai‘i has implemented a mandatory 25 percent Water Restriction for customers in the following areas:
AFFECTED AREAS: MAKALEI, KALAOA, KONA PALISADES, KEĀHOLE, PALAMANUI, KOHANAIKI, KALOKO, KALOKO MAUKA, HUALĀLAI; NORTH KONA, HAWAI‘I.
Water restriction measures are needed due to the failure of Hualālai Deepwell on Monday.
Meanwhile, the following areas in North Kona remain under a water conservation notice that calls for a voluntary 10 percent reduction in water use: KAHALU‘U, KEAUHOU,
KAILUA-KONA, HONOKŌHAU, KEALAKEHE, KEAHUOLŪ, KEŌPŪ, HŌLUALOA, WAI‘AHA.
The 25% Water Restriction will preserve adequate water supplies and pressure to meet the community’s drinking, cooking and hygiene needs. DWS will continue monitoring the
water system and make necessary adjustments. You will be kept informed of any changes in water supplies.
Please use water wisely and sparingly. Customers should refrain from irrigation, washing cars, and other unnecessary water uses while the water restriction is in effect. Taking
short showers, hand- washing dishes, fixing leaky toilets and turning off the faucet while brushing teeth are easy ways to reduce water use.
DWS has approved expedited purchase of replacement parts in efforts to return the Hualālai Deepwell back to service.
DWS stresses that water quality is not threatened by the loss of the well. Customers’ water remains safe to consume and continues to meet or exceed federal drinking water
regulations. Water filtration, boiling and other home purification practices are unnecessary.
For more water conservation tips, please visit www.hawaiidws.org, call 961-8050 during normal business hours or email dws@hawaiidws.org. Please call 961-8790 to report
after-hours emergencies.
