Seacliff 1 & Seacliff 2 Pump Stations and Force Main Upgrades

What's a Pump Station and Force Main?

Our combined sewer system is mostly gravity operated, but in some parts of the City, pump stations are necessary to pump combined wastewater flows to treatment facilities. To convey the flows from the pump stations, force mains are the pressurized pipes that help move flows from the pump station and through the system. Many of our aging pump stations and force mains are being upgraded as part of the Sewer System Improvement Program.

Project Benefits:

• Maintain critical sewer system services by upgrading both Seacliff 1 and Seacliff 2 Pump Stations and Force Mains
• Meet seismic standards
• Increase sewer system reliability
• Protect water quality and aquatic life in the Bay

About the SSIP

• The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a citywide investment to upgrade our aging sewer system and provide a more reliable, sustainable, and seismically safe system now and for future generations. The SSIP includes a series of facility upgrades at the Southeast Treatment Plant (SEP) located in the Bayview neighborhood of San Francisco.
