Project Purpose and Need
This project will rehabilitate or replace portions of the North Shore Force Main (NSFM) that are susceptible to failure. The NSFM provide sewer services to over 350,000 people in San Francisco on a regular work day. In order to protect water quality, the NSFM is almost always in service.
The existing NSFM is at the end of its useful life with portions having undergone emergency repairs in 2008 and 2012. Due to the fact that the NSFM is almost always in service, there was a portion of the NSFM that could not be fixed during the emergency repairs until a redundant pipe is available.
In winter 2015, a new redundant force main was completed, which allowed SFPUC to assess and plan for the repair of this portion of the force main. In order to control and direct flows between the NSFM and the new redundant force main, a new valve in an underground, concrete valve-vault, and other mechanical & electrical components would also be constructed.
- Increase sewer system reliability and continue to provide sewer services for approximately 350,000 people in the area.
- Protect water quality and aquatic life in the Bay by ensuring combined sewage is conveyed to the Southeast Treatment Plant.
North Shore Force Main: Spring 2020 - Fall 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.
