Southeast Treatment Plant Maintenance Buildings
Overview
Built in 1952, the Southeast Treatment Plant is the City’s largest wastewater treatment facility, but many of its facilities are past their useful life and generate odors that impact the neighborhood. We are investing over $3 billion in critical upgrades to transform this facility into a modern resource recovery center. By doing so, we will continue to protect our communities and environment while creating an attractive workplace and neighborhood asset.
Project Milestones
- Project Approval: January 2025

Project Background
New Operations, Engineering, and Maintenance Buildings
The Operations, Engineering and Maintenance Buildings Project will provide much-needed workspace, offices, and maintenance area for SFPUC staff at the Southeast Treatment Plant. The project – at the north corner of Jerrold Avenue and Phelps Street – will replace an existing building that is beyond its service life, as well as two temporary office trailers.
Like many of the treatment facilities at the Southeast Treatment Plant, the buildings that house SFPUC staff who operate and maintain the plant are well past their useful life, and the cost to maintain these outdated facilities continues to rise. The new staff buildings will help meet operating needs and support efforts to maximize the efficiency and value of the Southeast Treatment Plant. This is essential to supporting the SFPUC Wastewater Enterprise’s long-term business plan and ensuring delivery of services for the next generation while also investing responsibly and continuing to be strong environmental stewards in the Bayview neighborhood.
