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 provides 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.

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.
