Home

• 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
