|The SFPUC and San Francisco Arts Commission are commissioning artwork for the new Headworks Facility
|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 summer 2018. Sign-up here and visit sfwater.org/sepconstruction 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.
Headworks Facility Project
Built in 1952, the Southeast Treatment Plant (SEP) treats 80% of the City’s wastewater, but many of the SEP’s aging facilities have passed their useful lives and need to be upgraded and modernized.
The first step in the wastewater treatment process occurs at the Headworks facility where debris (such as baby wipes) and grit (like sand) are removed from the wastewater stream. This process is critical to protect downstream equipment, help control odors, and ensure that the SEP can operate efficiently. The existing 35-year old Headworks facility is at the end of its useful life and is unable to adequately perform these functions.
Project Purpose and Need
The Headworks Facility Project (Project) will construct a new Headworks facility, modify the Bruce Flynn Pump Station, and construct a new odor control structure. The Project will provide the following benefits:
- Continue to protect public health and the environment.
- Minimize odors using advanced odor control equipment.
- Meet current seismic standards to better protect the facilities from earthquakes.
- Improve operational reliability and flexibility.
- Increase efficiency of treatment processes and protect downstream equipment.
- Achieve the adopted Levels of Service goals for wastewater treatment.

Starting in spring, the San Francisco Public Utilities Commission (SFPUC) and the contractor, Sundt/Walsh, a Joint Venture, will begin construction for approximately five years, which will include:
What to Expect During Construction
- Establish a contractor work and staging area along Evans Avenue
- Modifications to Bruce Flynn Pump Station and facilities inside the SEP
- Modifications to existing underground combined sewer system in the vicinity of Rankin Street and Evans Avenue
- Shifting the four traffic lanes on Evans Avenue to establish safe construction zone
- Demolition of old Headworks Facility on Evans Avenue
- Construction of new Headworks Facility in same area as old facility
No parking along Evans Avenue, between Rankin and Quint streets. Pedestrian access and four lanes of traffic will be maintained.
- Noise, vibration, dust, and traffic impacts in the work zone.
- Residents near the work zone will maintain access to their homes and businesses.
- A city construction inspector will be on-site during work hours. Inspectors typically wear a yellow safety vest and hard hat.
- Construction Hours: Monday through Friday from 7:00 a.m. to 8:00 p.m.
- Nighttime and Weekend Work: Construction could occur as needed on Saturdays and Sundays from 7:00 a.m. to 8:00 p.m. Standard SFPUC practice requires advance notification to area residents and businesses prior to weekend and nighttime activities.
- Holiday and 24-Hour Work: If holiday or 24-hour construction is needed for critical facility connections, advance notice will be provided.
- Transportation Impacts: Streets will be open for traffic throughout construction, with optional detour routes available. Delays should be expected.
- Parking Impacts: A lane shift will occur on Evans Avenue between Rankin and Quint streets in the spring of 2018. Construction equipment will be staged in the southbound parking lane of Evans Avenue. Four lanes of traffic will be maintained, however there will be no parking on Evans Avenue between Rankin and Quint streets. “No-parking” signs will be posted 72 hours in advance.
- Muni: No bus impacts are expected at this time.
