Channel Force Main Intertie
Overview
The San Francisco Public Utilities Commission (SFPUC) operates a combined sewer system that collects and treats 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.
The Channel Force Main Intertie Project will increase the reliability, provide operational flexibility, and allow for future inspections and maintenance.

Project Background
The existing 66-inch Channel Force Main transports wastewater from the northeastern part of San Francisco to the Treatment Plant.
The Channel Force Main is over a mile long and is almost always in use. This project will construct a new pipeline connection and control systems along the existing force main. When completed, dry-weather sewage flows can bypass a portion of the existing force main.
These upgrades will provide operational flexibility for SFPUC to maintain sewer services. In addition, the completed project would allow SFPUC to inspect and rehabilitate up to a quarter of the existing force main in the future. The project will also install control panels in the sidewalk along Cesar Chavez Street, between Indiana and Pennsylvania streets, and replace existing air valves at two locations on Indiana Street, near the 20th and 25th street intersections.
Project Benefits
- Increase reliability of our City’s critical sewer system
- Provide operational flexibility to key sewer system infrastructure
- Allow for future inspections and maintenance
