20 SEWER SYSTEM IMPROVEMENT PROGRAM | Grey. Green. Clean. Oceanside Treatment Plant Located next to the San Francisco Zoo, the Oceanside Treatment Plant is responsible for treating 20% of the City’s wastewater on the Westside. The Oceanside Treatment Plant (OSP) requires renovations to maintain efficient operation, improve seismic reliability, and to extend the useful life of the equipment. As a result of the bids received in December 2018, the Westside Pump Station Reliability Improvements project design team is revisiting the project to optimize the scope to best fit within the available project budget. Construction is anticipated to begin Summer 2020. The Digester Gas Utilization Upgrade Project began construction in winter 2018, replacing and upgrading the existing outdated biogas energy recovery system at OSP. Biogas, the natural byproduct from the wastewater treatment process, provides a 100% renewable alternative energy source to fossil- fuel that helps co-generate electrical power and produce hot water required for the plant wastewater treatment processes.
