Force Main Rehabilitation at Embarcadero and Jackson Improvements
Overview
Watch this video and read this story on the recently completed Force Main Rehabilitation at Embarcadero & Jackson Improvements Project!
These upgrades included construction of new sewer junction structures along the Embarcadero, rehabilitation of approximately 190 linear feet of the North Shore Force Main via slip lining a 28-inch diameter pipe underneath the Embarcadero to newly constructed structures, and rehabilitation of an additional 50 linear feet of sewer underneath the Jackson Street combined sewer discharge structure. Construction of a new valve and controls vault will enable wastewater management staff to improved ability to direct combine sewage flows.

Project Background
The existing NSFM is at the end of its useful life with portions having undergone emergency repairs in 2008 and 2012. Due to the fact that the NSFM is almost always in service, there was a portion of the NSFM that could not be fixed during the emergency repairs until a redundant pipe is available.
In winter 2015, a new redundant force main was completed, which allowed SFPUC to assess and plan for the repair of this portion of the force main. In order to control and direct flows between the NSFM and the new redundant force main, a new valve in an underground, concrete valve-vault, and other mechanical & electrical components would also be constructed.
Project Benefits
- Increase sewer system reliability and continue to provide sewer services for approximately 350,000 people in the area
- Protect water quality and aquatic life in the Bay by ensuring combined sewage is conveyed to the Southeast Treatment Plant construction
