Welcome to the new Southeast Treatment Plant (SEP) construction web page. You asked to have up-to-the-minute information on what the SFPUC is doing in your neighborhood. We heard you! We want to make sure you are prepared for our construction activities.
Southeast Treatment Plant Construction Look-Ahead
- The contractor will be performing 24-hour work beginning October 4, 2019, to make repairs ahead of the rainy seasons. Expect continuous construction noise around the Southeast Treatment Plant during the next two weeks.
- Short duration, temporary lane closures on Evans Avenue will occur as crews relocate large equipment currently staged along Evans. Expect increased traffic during these operations. Crews continue to work extended hours to complete critical work before the start of the rainy season.

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.
