SFPUC will replace its existing, outdated solids treatment facilities with new biosolids digester facilities. The new facilities are designed to produce higher-quality Class A biosolids, capture and treat odors more effectively, and maximize biogas utilization and energy recovery. This project will provide a new, efficient solids treatment system, ensure treatment reliability by meeting current seismic standards and improving standard operations, and reduce the impact on the adjacent community by providing advanced odor control.
- Produces up to 24,000 dry tons of Class A biosolids annually by 2045.
- Ensures treatment reliability by meeting current seismic standards and improving standard operations.
- Reduces operating costs by improving energy efficiency and recovery.
- Minimizes impact on neighborhood by significantly reducing noise and odor problems.
- Reduces the air quality impacts of the plant.
- Provides quality job-training opportunities during design, construction, and operations.
- Original loan executed in 2018 saves San Francisco Public Utilities Commission up to $226 million from financing with a WIFIA loan compared to a bond issuance.
- Re-execution of the WIFIA loan in 2020 saves the San Francisco Public Utilities Commission an additional $432 million.
