The San Francisco Public Utilities Commission signed off on a $1.3 billion plan to replace the 60-year-old solid wastewater processing facilities at the city’s Southeast Treatment Plant.
The so-called biosolid digester facilities project represents the cornerstone of the SFPUC’s 20-year, $6.9 billion plan to modernize and improve the city’s aging sewer infrastructure. The Southeast Treatment Plant, located in Bayview-Hunters Point, is the workhorse of the city’s sewer treatment system, processing about 80 percent of San Francisco’s wastewater.
In addition to making the city’s solid wastewater treatment more efficient — the SFPUC will build five digesters to replace the nine that exist today— the new facility will also be built farther away from people’s homes, helping to limit the foul odors that can emanate from the plant. The SFPUC has pledged to keep the odor contained to the treatment plant’s fence line.
To help offset some of the costs of planning and construction, the SFPUC is working with the federal Environmental Protection Agency to secure a $625 million low-interest loan through federal Water Infrastructure Finance and Innovation Act. The agency is also seeking a $651 million loan from the State Revolving Loan fund.
The SFPUC anticipates construction will begin this fall and last through May 2024.
