At Work in Your Neighborhood
Built in 1952, the Southeast Treatment Plant (SEP) treats 80% of the City’s wastewater, but many of the plant’s facilities need to be upgraded or replaced. The Sewer System Improvement Program (SSIP) projects at the SEP focus on making the plant smell better, look better, operate more efficiently, and protect our critical equipment in the event of an earthquake.
SSIP projects at the Southeast Treatment Plant will accelerate the SFPUC’s vision to transform San Francisco’s largest wastewater treatment plant into a start of the art resource recovery facility, a City destination, a proud neighborhood asset and an attractive workplace.
