This project will rehabilitate or replace portions of the North Shore Force Main (NSFM) and the Drumm & Jackson Streets sewers that are susceptible to failure. The Drumm & Jackson sewer boxes, which are larger than 6-feet wide by 7-feet high, collect and transport combined wastewater by gravity to the North Point Pump Station, where the combined wastewater is pumped inside the NSFM towards the Southeast Treatment Plant. Together, the Drumm & Jackson Sewers and the NSFM provides sewer services to over 350,000 people in San Francisco on a regular work day.

The existing NSFM is at the end of its useful life with portions having undergone emergency repairs in 2008 and 2012. The NSFM is almost always in use and allowable construction work hours are limited. A portion of the NSFM cannot be rehabilitated without a new redundant force main, which was recently completed in Winter 2015.  During the redundant force main work, the SFPUC observed severe corrosion inside the sewer boxes on Drumm & Jackson Streets; therefore, repair work associated with rehabilitating the sewer boxes is also included in this project.

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.

Proposed construction schedule: Summer 2017 - Winter 2018

What to Expect During Construction






Construction is expected to last 16 months and will use both trenchless (slipline) and open-cut construction methods. Trenchless methods are used as much as possible to reduce traffic disruptive in the surrounding streets.

  • Sewer service in the area will NOT be interrupted during construction. 
  • Street parking will not be allowed near construction zones. “No-parking” signs will be posted 72 hours in advance. 
  • Streets will stay open for traffic throughout construction, with reduced traffic lanes and optional detour routes available. Traffic delays should be expected. 
  • No bus impacts are expected at this time.
  • Noisy work will be conducted in compliance with the San Francisco Noise Ordinance. Most construction work is expected to be performed during daytime hours.
  • If necessary, odor control measures will be in place during construction. 

A 30-day and 10-day notice will be distributed prior to construction to residents and businesses within the project area detailing traffic impacts and project details.

About the SSIP

The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a 20-year citywide investment to upgrade our aging sewer system and provide a more reliable, sustainable, and seismically safe system now and for future generations. The SSIP includes a series of facility upgrades at the Southeast Treatment Plant (SEP) located in the Bayview neighborhood of San Francisco. Click here to learn more about the SSIP.
