Waikoloa Water System which is owned and operated by the Hawaii Water Service Company (HWSC), with service provided by its subsidiary West Hawaii Utility Company (WHUC). The Waikoloa Water System is supplied by seven (7)wells located inland of Waikoloa Village that draw water from the Waimea Aquifer. According to the Assessment of Potential Impacts on Water Resources study conducted by Tom Nance Water Resources Engineering dated June 2021, the project at full buildout is anticipated to require an additional 537,150 GPD which would constitute a 15% increase in potable water used by the resort. According to the same report, the additional draw from the Waimea Aquifer would increase from an average of 13.2 MGD to 13.74 MGD, which is less than the sustainable yield of 16 MGD set by the Commission on Water Resources Management(CWRM) in their 2019 Water Resources Plan Update. Thus, it is unlikely that the additional water required for the project will have an adverse effect on the aquifer. The project area is served by two (2) 12-inch diameter waterlines. The proposed water system will connect to the line within the northern part of Waikoloa Beach Drive. By letter dated June 8, 2021, HWSC indicated the willingness and ability to serve the Kumu Hou project with potable water subject to the execution of an extension agreement and payment of a Contribution in Aid of Construction (see Appendix 14 of the application). 43. Project Related Irrigation: Groundwater at the WBR is derived from the `Anaeho`omalu Aquifer System, including existing brackish water wells developed for irrigation purposes. The landscaped areas of the Kumu Hou project area are estimated to require about 0.31 MGD for irrigation. To accommodate this need, the Kumu Hou project includes a new proposed brackish water irrigation system (including two wells and distribution system) to be located in"Area C". This improvement will eliminate the reliance on potable water for irrigation purposes within the project area. Additionally, the applicant estimates that repurposing of nine fairways, of which an estimated 59.9 acres have been irrigated, should offset this new demand and the overall withdrawal of groundwater at the resort is expected to decline by an estimated 0.3 to 1.0 MGD. The reduced need for groundwater is also attributable to the increased production of wastewater, which will allow the resort's remaining 27 fairways to be irrigated with a -23-
