The primary goal of the proposed project is to construct the necessary pipelines and pump stations to successfully convey all current and future wastewater into a regional sewer system serving south Yuba County. The proposed pipeline would connect to OPUD's force main (currently under design) near Rancho Road and State Route 65. OPUD would convey the flow to OPUD's WWTP, where the flows would be treated to a tertiary level and discharged into a tributary to the Feather River. Additionally, three new pump stations would be constructed along the new pipeline to convey all projected flows to the OPUD point of connection and a new Public Works corporation yard would be constructed within the Pump Station 2 site. After construction of the pipeline and pump stations, it is anticipated that the City's existing WWTP would be decommissioned, though the possibility exists for the WWTP to remain in operation
for an interim period. Decommissioning of the existing WWTP would result in the City losing its current base of operations for wastewater personnel, equipment, and controls. This loss of space at the existing WWTP would be offset by the construction of a new corporation yard at the location for Pump Station 2. The eight-mile pipeline alignment would begin at the existing pump station on Malone Avenue and head due east from the pump station, across a largely vacant parcel, then under SR 65 and the UPRR mainline track, to proceed east along Sixth Street to Spenceville Road. The proposed alignment would follow Spenceville Road for approximately one-mile just past its intersection with Jasper Lane, then connect to Pump Station 2, at which point the pipeline alignment would head due north along Jasper Lane for approximately 2.3 miles. From the northmost end of Jasper Lane, the pipeline would head due west through private farmland property and would be routed along existing dirt roads to the
maximum extent feasible to avoid sensitive habitats and active agricultural lands. Shortly after crossing Best Slough, the pipeline alignment would head north and cross two UPPR spur tracks after which it would head west on a short segment of South Beale Road, where it would turn north toward a proposed undercrossing at the UPRR mainline, near the intersection of SR 65 and Rancho Road to the point of connection with OPUD's sewer system.
