CONSTRUCTION UPDATE

Spear Street Mission to Howard - The pit area just south of the Mission/Spear intersection that was used to install ~300 feet of pipe under the Mission/Spear intersection has been backfilled and sheet piles removed.

Spear Street Market to Mission - Construction crews drove sheet piles to create a perimeter for the pit midway on Spear Street (approximately 55 Spear Street parking garage entrance). The pit will be used to install the steel casing for this section.

 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.
