Current Project Timeline:
Spring 2017 – Release of Draft Environmental Impact Report (EIR)
Early 2018 – Final EIR
Summer 2018 – Start Construction
Summer 2024- Construction Complete
Summer 2025- Facility Start-Up
On May 3rd, 2017 the Draft EIR was released by the San Francisco Planning Department for public review and comment. The comment period closed on June 19, and the Final EIR is anticipated in early 2018. Once approved, project construction is anticipated to begin in fall 2018. Community meetings and outreach activities will continue throughout the planning and construction phases.

|Conceptual rendering of the proposed Digester Facilities
Built in 1952, the Southeast Treatment Plant (SEP) is the City's largest wastewater treatment facility and treats 80% of the City's sewage and stormwater flows. Many of the existing SEP solids treatment facilities
are over 60 years old, require significant maintenance, and are operating well beyond their useful life. To ensure our sewer system continues to provide sustainable, reliable operations, we are committed to upgrading our largest treatment facility. Several years of planning and engagement with the community led to the development of a plan to address the long-standing issue of odors and seismic vulnerability, as well as other operational challenges related to the solids handling facilities at the SEP.
The proposed Biosolids Digester Facilities Project (BDFP) would replace and relocate the outdated existing solids treatment facilities with more reliable, efficient, and modern technologies and facilities. The new facilities would produce a higher quality biosolids, capture and treat odors more effectively, and maximize biogas utilization and energy recovery for the production of heat, steam and energy. In addition, the project would locate the digesters farther away from existing residences, make visual improvements in and around the SEP and allow us to meet our Levels of Service goals.
• Address aging infrastructure – Construct new modern, proven and efficient treatment technologies
• Maintain regulatory compliance
• Build critical processes with redundant infrastructure to provide reliability and operational flexibility
• Improve seismic reliability
• Beneficially use 100% of Biosolids and Biogas produced
• Improve odor, noise and visual quality

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
