Drumm & Jackson Streets Sewer Improvements

Project Purpose and Need

Project Materials
Project Fact Sheet
Construction Notice


The Drumm & Jackson Street Sewer Improvements project (Drumm/Jackson) will rehabilitate approximately 805 feet of the existing Drumm Street box sewer and approximately 205 feet of the Jackson Street box sewer. The Drumm & Jackson sewer boxes serve approximately 25% of the City and County of San Francisco. They are large reinforced concrete box sewers (e.g. the Drumm box sewer is more than 7.5-feet wide by 6-feet high) that collect and transport combined wastewater by gravity en-route to the Southeast Treatment Plant. The Drumm & Jackson sewers were constructed in approximately 1913. These critical sewers have severe deterioration and corrosion and are in need of repair.

Drumm & Jackson project benefits:

  • Increase sewer system reliability; together the Drumm & Jackson sewers contribute to servicing over 350,000 people in San Francisco on a regular workday.
  • Protect water quality and aquatic life in the Bay by ensuring combined sewage is conveyed to the Southeast Treatment Plant.

Proposed construction schedule: 

  • Construction is estimated to start spring 2018 and last approximately 9 months. 
  • NOTE:  The Drumm/Jackson and Embarcadero North Shore Force Main (NSFM) projects were planned to occur at the same time, however, the projects will now occur separately. The SFPUC has decided to phase the scope of work into two different construction contracts (1) Drumm & Jackson and (2) North Shore Force Main. This will allow us to properly locate and assess the condition of the existing underground facilities that are along the Embarcadero while moving forward with the urgent repair of the Drumm & Jackson Street sewers. We will provide an update and additional information once we have a schedule and more project details.



What to Expect During Construction






The majority of the rehabilitation will be by trenchless (below ground) construction method to minimize street level construction activities. There will be some above ground construction for access points to the sewer and portions of the traffic lanes on Drumm Street may be closed for worker safety. 

  • 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.
