Project Site
Context. The headworks project is located at the SFPUC Southeast Plant which treats 80% of San Francisco’s wastewater. This project replaces the existing headworks which is at the end of its useful life. The project site is at the corner of Evans Avenue and Rankin Street in the Bayview neighborhood. On the plant side, the site is hemmed in by an above ground treatment basin.

Program: Influent from the City enters the Headworks via the Bruce Flynn Pump Station. The Screening Facility removes large objects and transfers them to Screenings Handling for trucks to haul away. The influent then enters the Grit Tanks to remove smaller particles, which are transferred to Grit Handling for trucks to haul away. All air is captured and routed back to Odor Control for filtering. Liquids and solids are piped to respective treatment areas at the plant.
