Golden Hills Wastewater Treatment System Improvement Project

Golden Hills Wastewater Treatment System Improvement Project

The project consists of the rehabilitation of the existing old sewage system collection components used by the privately managed Golden Hills Sanitation Company (GHSC) to provide service to 185 existing connections and areas planned to have sewer service by the original design. The GHSC is currently in receivership and two options have been identified for treatment of the sewage. The system rehabilitation common to both options includes replacing components that are not functioning properly, including 6 inch and 8 inch collection pipes, 6 inch, 8 inch, 12 inch gravity main pipes, manholes, and removal of the existing lift station on Woodford Tehachapi Road. The two options are: Option A, rehabilitation of the Golden Hills Wastewater Treatment Plant (WWTP) and related infrastructure upgrades; and Option B, conveyance of wastewater to the City of Tehachapi WWTP and related infrastructure upgrades and decommissioning of the Golden Hills WWTP. The purpose of evaluating two options for the proposed project is to inform decision makers of the potential environmental impacts associated with both Option A and Option B for full disclosure and informed decision making. In addition to the system upgrades common to both options, Option A would include the rehabilitation and continued operation of the Golden Hills WWTP, with an opportunity to provide treatment for up to 0.10 million gallons per day of future sewage effluent loads according to the plant's rated capacity. Option B would include installation of a lift station and 4-inch diameter force main pipeline to the City of WWTP at Tucker Road and Red Apple Avenue for effluent treatment and disposal. The route for the force main would be entirely within either GHCSD property or public right of way and the Golden Hills WWTP would then be decommissioned.
