The following projects are being implemented as part of the Sewer System Improvement Program and are currently in pre-construction, construction, or have been recently completed.
Grey Infrastructure Projects
Through Phase 1 of the SSIP, our planned improvements will upgrade our critical aging and seismically vulnerable grey infrastructure like pump stations, sewer pipes, transport storage boxes and treatment facilities into a state of good repair.
Wastewater Treatment Facilities Projects (Southeast Treatment Plant, Oceanside Treatment Plant and North Point Wet Weather Facility).
For more information about construction activities at the Southeast Treatment Plant, visit sfwater.org/SEPConstruction.
The proposed upgrades would replace and relocate the outdated existing solids treatment facilities with more reliable, efficient, and modern technologies and facilities.
|
The project would replace the function of two existing headworks facilities, modify the Bruce Flynn Pump Station, and construct a new odor control structure.
|
Improvements and modifications are needed to ensure the facility is reliable and operationally flexible, that it contains equipment redundancy, and remains compliant with State and Federal regulations.

Other Projects
• Existing Digesters Gas Handling Improvements
• North Point Facility Outfall Rehabilitation Project
• Digester Gas Utilization Upgrade Project

Collection System Projects
Our collection system includes the sewers, large transport/storage box structures, force mains (pressurized sewer pipes) and pump stations which work together to collect and transport wastewater to our treatment plants.
Green Infrastructure Projects - Sustainable Stormwater Management
The SSIP will also construct, monitor and evaluate eight green infrastructure projects to manage stormwater before it enters our combined sewer system in each of San Francisco's eight urban watersheds. For information on our Green Infrastructure Grant Program, click here.
