b. History There was no water service available to the Iki Place subdivision when it was developed in the early 1960's. Water for the residences was provided by individual rainwater catchment systems. When the water main within the Mamalahoa Highway was extended mauka of the subdivision, 5/8"meters were installed within the Mamalahoa Highway ROW to serve some of the homes. PVC lateral lines run cross country from the highway to the residences, some of which are up to 2,000 feet from their respective meters. c. Condition of Facilities The existing PVC and HDPE service lines from the meters at the highway run overland to homes via the Kona Church of God Road ROW and then through neighboring properties. These lines are subject to leaks and potential contamination should infiltration occur due to pipe failure. It is often difficult to locate the source of leaks due to the extraordinarily long overland routes of these lines. Furthermore, there are no fire hydrants within the subdivision to provide fire protection to the homes within it. d. Financial Status of Existing Facilities The Department of Water Supply's Financial Statements are attached as Exhibit A. There is no site-specific operation and income data available. e. Water Audits In June 2016,Act 169, Session Laws of Hawaii 2016,was signed into law by the Governor. This Act requires Hawai`i public water utilities to complete and submit validated water audits to the State of Hawai`i,Department of Land and Natural Resources, Commission on Water Resources Management, on an annual basis. The water audits for the North Kona Water System has resulted in a decrease of the Infrastructure Leakage Index over the years since the initial water audit conducted in 2017. 4. NEED FOR THE PROJECT a. Health, Sanitation and Safety The health and safety of the residents of the Iki Place subdivision is jeopardized by the current sub-standard water system. Potential contamination and leakage problems exist due to reasons described previously in Section 3c. County water system standards also call for fire hydrants every 600 feet based on the existing lot sizes and zoning, so that no parcel is further than 300 feet of a hydrant. No parcel within the subdivision currently falls within this distance,leaving the homes within it particularly underserved with regard to fire protection. b. Aging Infrastructure The existing service lines which serve all 15 homes within the Iki Place subdivision are decades old in most cases and prone to breakage due to-degradation and impact. A visual inspection of these lines shows many repaired breaks along their respective lengths from years of use and exposure to the elements. c. System Operation and Maintenance The proposed water system will become part of the North Kona water system which consists of wells and pumping stations. No future extension of the proposed system is anticipated and 6
