Project Purpose and Scope of Work

The San Francisco Public Utilities Commission (SFPUC) operates a combined sewer system that collects and treats wastewater (sewage and stormwater). Our Sewer System Improvement Program (SSIP) is upgrading and modernizing our system to ensure we can continue to protect public health and the environment now and into the future. 

As part of the SSIP investments, this project will rehabilitate the existing 100-year old sewer mains, located under Mission Street, between 16 th and 22nd Streets, as well as between 25th and Cesar Chavez Streets (the sewers between 22nd and 25th Streets are in good condition and do not need to be rehabilitated). To minimize impacts to the adjacent residents and businesses, most of the sewer rehabilitation work were designed to be performed using a trenchless method called Cured-in-Placed Pipe (CIPP) sfpuc.org/curedpipe. This project will also relocate a portion of Emergency Firefighting Water System (EFWS) pipeline and a fire hydrant at the intersection of 20th and Mission Street, to make room for the sewer improvements.

In addition, SFPUC coordinated with another city agency, San Francisco Metropolitan Transit Authority (SFMTA), and included transit improvements, such as bus stop replacements and associated sidewalk and traffic signal work, near the intersection of Mission and 20th Streets, to be completed with the sewer construction contract. The transit related work is sponsored by SFMTA and information about the bus stop replacement project can be found in SFMTA’s website and the contact number below.
