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



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. 


Spear Street: Market to Mission

Installation of 54” casing continues from approximately mid-block toward Market Street. We have completed approximately 60 feet of the 180 linear feet that need to be done. Once casing installation is completed, the force main pipe will be inserted and tested before final pavement restoration is performed on this block.

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.
