Project Summary
The District’s Infrastructure Asset Management Plan update of 2021 identified these three lift stations as the highest priority lift stations for upgrading based on a District-wide risk assessment. Since their configurations are similar, they were combined into one project to take advantage of economies of scale. LS20 is in Larkspur Landing next to East Sir Francis Drake Blvd, and near the northbound 101 on-ramp. LS31 and LS32 are located on Riviera Circle at Via la Brisa and Corte del Bayo, respectively, in the Larkspur Marina neighborhood.
The project will convert the lift stations to submersible pump configurations, saving maintenance and energy costs. The project also includes replacing the two small force mains for the LS31 and LS32 lift stations as they are made of deteriorating ACP pipe, an inferior pipe material used in the 1960s and 1970s that is targeted for replacement by the District throughout the service area. New electrical control panels, communications equipment, and flow meters will improve reliability of the lift stations and allow for faster response times to issues at each station.
Project Update - July 28, 2025:
LS20 is currently under construction, with recent progress including the concrete pour for the new flow meter vault, installation of temporary electrical service, and setup of bypass systems. LS31 is complete, and final completion of LS32 is pending PG&E energization.
