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 to meet our Levels of Service. One of the highest priority upgrades at the SEP is replacement of the Headworks facility. Headworks is where all wastewater flows converge, and is the first step in the wastewater treatment process where debris (such as baby wipes) and grit (like sand) are removed from wastewater at the beginning of the treatment process. To see how the headworks treatment process works, check out this diagram

Project Purpose and Need

The project would replace the function of two existing headworks facilities, modify the Bruce Flynn Pump Station, and construct a new odor control structure. When completed, the project will help minimize odors, provide seismic reliability, reduce operational costs, and ensure the adopted Levels of Service for wastewater treatment are met.

Project objectives are to:

  • Provide redundancy, reliability and operational flexibility
  • Maximize odor control within the treatment facility
  • Improve the efficiency of the treatment process
  • Protect downstream equipment from the harmful effects of grit and debris
  • Meet the permitted capacity of 250 million gallons per day

What to Expect During Construction

The Headworks Facility Project will include utility improvements to the sewer lines under Evans and Davidson Avenues and Quint and Rankin Streets, and facility improvements to the Bruce Flynn Pump Station located at the northeast corner of Evans Avenue and Quint Street. Construction will also occur inside the plant to prepare for and construct the new facilities. As construction nears, this webpage will be updated with information on what to expect and how to contact the project team with questions.


About the SSIP

The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a 20-year citywide investment to upgrade our aging sewer system and provide a more reliable, sustainable, and seismically safe system now and for future generations. The SSIP includes a series of facility upgrades at the Southeast Treatment Plant (SEP) located in the Bayview neighborhood of San Francisco. Click here to learn more about the SSIP.
