North Service Area Pipeline Phase B and Terminal Tank Preliminary Design Report

The Sacramento County Water Agency (SCWA) is soliciting proposals from engineering firms to develop the Phase B North Service Area (NSA) Pipeline and Terminal Tank Preliminary Design Report (PDR). This procurement seeks professional engineering services to design water infrastructure for the Zone 40 Water Supply Master Plan, specifically focusing on a new pipeline and terminal tank system. The project requires developing a comprehensive preliminary design report covering approximately 7 miles of pipeline with varying diameters, including 10,500 feet of 66-inch and 20,000 to 24,000 feet of 54-inch sections. Key deliverables include geotechnical services, environmental documentation, right-of-way analysis, and design recommendations for water infrastructure serving the Mather, Sunrise Corridor, and Sunridge systems. The RFP was published on December 30, 2024, with proposals due on February 27, 2025, at 2 PM, and a question submission deadline of February 13, 2025, at 4 PM. The project timeline includes a kick-off meeting on May 27, 2025, and a preliminary design presentation scheduled for January 29, 2026.

The procurement does not explicitly specify set-aside designations or restrictions on respondent organizations. The proposed project involves constructing two water storage tanks with a minimum capacity of 2.5 million gallons each and a current design capacity of 5.0 million gallons. The booster pump station is designed with a 35 MGD ultimate capacity and will include an operations and chemical building, emergency generator, and site improvements. The terminal tank site will be located south of Douglas Road, west of the Folsom South Canal. The consultant will be responsible for coordinating with the Department of Community Development and preparing environmental documentation under the California Environmental Quality Act (CEQA). While specific budget ranges are not detailed in the provided documentation, the project addresses critical water supply challenges, including mitigating groundwater contamination from the Aerojet plume, which suggests significant infrastructure investment potential.
