Construction at the Southeast Treatment Plant

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
    • Crews will begin weekend work August 31st to complete critical work before the start of the rainy season. This will mean 12-hour daily shifts, but minimal impacts to the community are anticipated.
    • Starting in early June, the contractor will begin work to demo the old Headworks building. This is a process that will take several months to complete. Intermediate construction noise and vibrations may be noticeable outside the work zone.

    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 state-of-the-art resource recovery facility, a City destination, a proud neighborhood asset and an attractive workplace.
