The Biosolids Digester Facilities Project (BDFP) will replace and relocate the outdated existing solids treatment facilities with more reliable, efficient, and modern technologies and facilities. The new facilities will produce a higher quality biosolids, capture and treat odors more effectively, and maximize biogas utilization and energy recovery. In addition, the project will locate the digesters farther away from existing residences and make visual improvements in and around the Southeast Treatment Plant.
This project will provide significant operational and functional improvements to this critical facility including:
Producing higher quality "Class A" biosolids that have greatly expanded beneficial uses.
Reducing odors from the treatment process.
Improving the ability for these critical facilities to withstand a 7.8 earthquake on the San Andreas fault, and a 7.1 earthquake on the Hayward fault.
Ensuring that the Southeast Treatment Plant can accommodate or adapt to the expected sea level rise of 36 inches by 2100.
The SFPUC is also leveraging these investments to provide opportunities to local residents and businesses who are most impacted by having this facility in the neighborhood:
Provide a more attractive look to the facilities to better fit in with the neighborhood.
Fund local public art guided by the Bayview Arts Master Plan.
Support local hire and local contracting goals and requirements.
Built in 1952, the Southeast Treatment Plant (SEP) is San Francisco's largest wastewater treatment facility, but many of its facilities are past their useful life and generate odors that impact the neighborhood. The San Francisco Public Utiltiies Comission (SFPUC) is investing over $3 billion to transform this facility into a modern resource recovery center, an attractive workplace and a neighborhood asset.
The Southeast Treatment Plant Biosolids Digester Facilities Project is part of the Sewer System Improvement Program (SSIP), a multi-billion-dollar citywide investment to upgrade San Franciscos aging sewer system. The SSIP is the result of an extensive community planning process and will ensure a reliable, sustainable and seismically safe sewer system now and for generations to come.
