Capital Improvement Program Existing Facilities The County provides wastewater treatment facilities, pumping stations, and laterals [o serve wastewater customers. A total of four wastewater treatment plants currently provide service for the County. The following list summarizes the facilities, their locations and existing plant capacities. Wastewater Treatment Plant Existing WWTP Design Facility Capacity (MGD) Eleele WWTP 0.4 Lihue WWTP I.5 Waimea WWTP 0.3 Wailua WWTP I.5 Proposed Facilities Table 3 presents the proposed capital improvement program (CIP) for the sewer utility for fiscal yeaz 1996 through fiscal year 2000. The program identifies approximately $44 million of improvements not including the expansions currently under construction at the Eleele and Lihue wastewater treatment plants. All costs include inflation allowances estimated at four percent (4%) per year. We have grouped the improvement projects into the five sewerage system service areas of Hanapepe-Eleele, Wailua-Kapaa, Waimea, Lihue, and Poipu-Koloa. Following is a brief description of the improvements for each area with the corresponding project costs for the study perjod. Hanaoeoe-Eleele Seweraee Svstem -The improvements in this area include rehabilitation of the existing collector sewer lines within the older sections of Hanapepe and Eleele, and construction of the Hanapepe Heights and Hanapepe Town collector sewers to provide service to those areas not presently served. Approximately 120 new users will be connected. The projects total $5,951,900. Wailua-Kaoaa Seweraee Svstem -The improvements in this area include the construction of the Kapaa town collector sewers, effluent disposal improvements, and a new wastewater facilities plan update for Wailua-Kapaa. Approximately 180 new users will be connected in the Kapaa area. The projects total $12,802,700. Waimea Seweraee Svstem -The improvements in this area include the STP expansion plans and construction, effluent disposal project, sludge holding tank, and the rehabilitation of the Waimea collector sewer. The timing of the STP expansion, currently planned for 1998, is dependent upon development. The projects total $15,755,500. Lihue Seweraee Svstem -The improvements in this area include an effluent disposal facilities plan, construction for the Lihue Industrial Parks, rehabilitation of the Lihue collector sewer, and construction of the Kupolo collector sewer. Approximately 80 new users will be connected to the system. The projects total $7,804,300.
