Construction Coming Soon!

Planning for construction is underway, with construction staging along the south side of Evans Avenue between Rankin and Quint streets and early construction activities anticipated in late 2017/early 2018. Sign-up here for Southeast Construction Updates!

Public art is an important part of our upgrades at the Southeast Treatment Plant (SEP). Click on the image to the left to learn more about the art wall that will serve as an exciting visual gateway to the Bayview Hunters Point community.

Built in 1952, the Southeast Treatment Plant (SEP) is located in the Bayview Hunters Point community and treats 80% of the City’s wastewater. Many of the SEP’s facilities are being upgraded and modernized to meet our Levels of Service, which provide specific, measurable goals and objectives that guide project selection and evaluate program success.

One of the highest priority upgrades at the SEP is replacement of the Headworks facility. Headworks is the first step in the wastewater treatment process where debris (such as baby wipes) and grit (like sand) are removed from wastewater as it begins the treatment process. Wastewater includes stormwater (rain runoff) and sanitary sewage from businesses and homes. Click here  to view a diagram to learn more about how the headworks treatment process works.

Project Purpose and Need
The existing Headworks facility is aging and unable to adequately screen grit, debris and sand, causing odors and affecting downstream equipment. The Headworks facility Project will replace two existing headworks facilities, improve the Bruce Flynn Pump Station, and construct a new odor control structure. View the fact sheet for more details.

The project purpose is to:
  • Continue to protect public health and safety.
  • Minimize odors using advanced odor control equipment.
  • Meet current seismic standards to better protect the facilities from earthquakes.
  • Improve operational reliability and flexibility.
  • Protect downstream equipment and improve the treatment processes.
  • Ensure the adopted Levels of Service for wastewater treatment are met.

What to Expect During Construction
The Headworks facility Project will include: Improvements to the sewer lines under Evans and Davidson Avenues and Quint and Rankin Streets. Improvements to the Bruce Flynn Pump Station located at the northeast corner of Evans Avenue and Quint Street. Construction inside the SEP 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.

Project Update: Proposed Public Art & Architectural Design
On June 19, 2017, the conceptual design for public artwork at the Headworks facility was presented to the Southeast Community Facility’s Facilities and Design Committee for review and feedback. On July 17, 2017 the project completed the second round of review of the architectural designs with San Francisco Arts Commission. The art and architecture chosen for the Headworks facility is evocative of the SFPUC’s vision to transform the SEP, 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.

About the SSIP
The Sewer System Improvement Program (SSIP) is a 20-year citywide investment to upgrade and modernize our aging and seismically vulnerable sewer system. The goal of the SSIP is to provide a more reliable, sustainable, and seismically safe system to ensure we can continue to protect public health and the environment now and for generations to come. The SSIP includes a series of facility upgrades at the SEP located in the Bayview Hunters Point neighborhood of San Francisco. Click here to learn more about the SSIP.
