New Headworks Facility

Overview

Built in 1952, the Southeast Treatment Plant is the City's largest wastewater treatment facility handling nearly 80% of San Francisco's combined storm and wastewater every year, however, many of its facilities are past their useful life and generate odors that impact the neighborhood.

The SFPUC is investing over $3 billion in critical upgrades transform this facility in the Bayview into a modern resource recovery center, including construction of the New Headworks Project. By doing so, we will continue to protect our communities and the environment while creating an attractive workplace and neighborhood asset that serves the entire City for decades to come.

When complete, the plant will work better, look better, and smell better for the neighborhood, our staff, and the entire City!

CONSTRUCTION UPDATES (Summer 2025)

Evans Avenue Restoration

As part of the New Headworks Facilities Project, crews have begun on the demolition of the last portion of the old Headworks building on the northwest side of the Southeast Treatment Plant. This 50 million gallons per day wastewater facility was deemed redundant with the successful completion and activation of the new 250 million gallon Headworks Facility that completed construction earlier this year. Demolition of this decommissioned facility is expect to be completed by late Fall 2025.
