The Westside Pump Station (WSS) is an all-weather facility that pumps the sanitary and stormwater flow  from the West side of the City to the Oceanside Treatment Plant. The WSS and associated facilities have been in service for numerous decades in the harsh marine environment. The aging mechanical and electrical infrastructure must operate daily to maintain water quality requirements.

Improvements and modifications are needed to ensure the WSS is reliable and operationally flexible, that it contains equipment redundancy, and remains compliant with State and Federal regulations. The Westside Pump Station Reliability Improvements Project is a part of the Sewer System Improvement Program (SSIP), a 20-year, multi-billion dollar citywide investment required to upgrade our aging sewer system.

Project benefits:
  • Critical functions built with redundant infrastructure
  • Upgrade plants with redundant electrical feeds
  • Add redundant pumps at major pump stations
  • Limit odor to within the treatment facility's fence line

Project schedule: The project design period has been extended to fall 2020 with an anticipated construction start date of spring 2021.


About the SSIP

The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a 20-year 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. Click here to learn more about the SSIP.
