The Southeast Treatment Plant, owned and operated by the San Francisco Public Utilities Commission (SFPUC), is the city’s largest wastewater facility. SFPUC is investing over $3 billion to upgrade and modernize the aging facility to reduce odors, be better prepared for earthquakes and sea level rise, and ensure operational redundancy and efficiency. Led by Brown and Caldwell, the Biosolids Digester Facilities Project is the largest upgrade (~$2B) and will positively impact the communities of San Francisco where we live and work—promoting resource recovery and reuse and providing economic and environmental benefits. The new facilities will produce a Class A biosolids product and implement modern technologies and facilities, including thermal hydrolysis pretreatment, anaerobic digesters, solids dewatering, solids thickening, odor control, and biogas/energy recovery facilities. When complete, the plant will be transformed into a resource recovery facility that smells better, looks better, and works better.

Brown and Caldwell is leading a team of dedicated subconsultants to deliver the design and provide construction support of this project, which include Jacobs, Black & Veatch, STRUCTUS, SRT Consultants, ENGEO, Forell/Elsesser, MWA Architects, MEI Architects, and others. The project is being constructed using the construction manager/general contractor delivery method by MWH/Webcor with support from many local skilled trade subcontractors.
