At Work in Your Neighborhood

Built in 1952 in Bayview-Hunters Point, the Southeast Treatment Plant is the City’s largest wastewater treatment facility, but many of its facilities are past their useful life and generate odors that impact the neighborhood. 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.

After years of planning and community engagement, major investments in the Bayview-Hunters Point community are underway. Overall, the SFPUC is investing over $2 billion into new facilities and equipment to reduce odors, be better prepared for earthquakes and sea level rise, and ensure operational redundancy and efficiency.
