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



Spear Street: Market to Mission

Spear Street will be closed to through traffic starting August 19 and continuing through September 4. In essence, Spear Street will become a cul-de-sac during that period, with entry and exit from Mission Street only. Right turns onto Spear from Market will not be permitted during this period. This will allow crews time to complete the crosswalk restoration work at Market/Spear as well as lay the concrete road base and follow up with the final asphalt paving.

OCS Restoration Work

Crews have begun the restoration of Overhead Trolley wires along Mission Street between First and Steuart streets. This involves overnight work between 10 p.m. and 5 a.m., however, it is non-disruptive quiet work involving pulling and placing wire using a bucket truck. 


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

We 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.
