NSCFM-Sewer Force Main, Water Main Relocation & Replacement, and Pavement Renovation



Spear Street: Market to Mission

Success! The SFPUC contractor has just completed the installation of the carrier pipeline under Spear Street from mid-block to Market Street, a full 180 linear feet. This follows last week’s successful breakthrough to connect the tunnel beneath Spear Street all the way to the Market Street Plaza area. Subsequently, the contractor placed the 54-inch casing. Then it was on to fusing the carrier pipeline and inserting it into the casing. Next up the contractor will connect several fittings to complete the structure. That will be followed by hydro-testing to insure the system’s integrity. After testing, various utility companies, including PG&E, will perform support restoration work prior to roadway restoration. Final activities will include backfilling the construction pits, removing the shoring and final restoration of the street.

Howard Street: Stuart to Spear and Spear Street: Howard to Mission

Pipe installation for this portion of the force main alignment has been completed on these blocks, and the contractor has been working hard to complete the sidewalk repair and concrete base replacement in preparation for paving activities in the coming weeks. A small portion of paving will be restored at the intersection of Howard and Spear at the end of this project once final testing is performed. We thank you for your patience as the contractor completes this work and look forward to completing paving and roadway striping on these blocks.


Project's Regular Work Days & Hours: Monday through Friday, 8:00 A.M. to 8:00 P.M. (notification will be provided for weekend/night-work)

 Project Description

The existing North Shore force main serves more than 350,000 people by transporting combined wastewater – sanitary sewage and stormwater – from the northeast part of San Francisco to the Southeast Wastwater Treatment Plant for treatment. The existing force main is near the end of its useful life and in need of repair. The completion of this new sewer project will enable the rehabilitation of the existing sewer line and ensure continued service to residents and businesses of San Francisco.

Comparing the Embarcadero wharf from centuries ago with today’s built up environment, helps us understand the difficulties the design engineers and contractor constantly struggle with as they encounter unmarked piers, buried brick sewers and other remains from the 1800s.
