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

Join our mailing list to be alerted of construction updates.



Spear Street Market to Mission - Starting the week of September 29, crews will be installing the casing for the sewer pipe for a few weeks. The project team is still working with utility providers to make sure the recently discovered unmarked utilities underground are removed or relocated prior to installing the sewer force main pipeline.

Spear Street at Howard - Construction crews finished the installation of two new catch basins at the northeast corner of Spear and Howard Streets. These will help mitigate stormwater flows at the intersection. We will complete the full paving process on Spear St at a later date when the North Shore Force Main project is done.

Spear Street at Mission - We still anticipate a need to close the Spear/Mission intersection one weekend in mid-October. We will notify you of this planned closure.

Drumm Street - The week of September 29, for a duration of approximately two weeks, in front of the Embarcadero Center 4, crews will start the installation of the concrete base in preparation for restoration of the sidewalk tile. Additional elements to complete on Drumm Street include median restoration and tree replacement to return the area to its pre-construction condition.

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.
