The Southeast Water Pollution Control Plant Biosolids Digester Facilities Project

May 30, 2019

THE PROJECTSan Francisco Public Utilities Commission (SFPUC) is the third largest municipal utility in California, and the Southeast Water Pollution Control Plant (SEP), is the SFPUC’s largest wastewater treatment facility, treating 80 percent of San Francisco’s sewage and storm water flows. The SEP Biosolids Digester Facilities Project (BDFP) is part of the SFPUC’s Sewer System Improvement Program (SSIP), a 20-year, multi-billion-dollar citywide investment to upgrade aging sewer systems. The BDFP aims to replace existing digester facilities with new, expanded, reliable, modernized and relocated facilities, as well as improve energy recovery and maximize control of odors.

The BDFP is one of the first projects in the U.S. to use the Thermal Hydrolysis Process which will enable the new facilities to produce higher quality biosolids, capture and treat odors more effectively, and maximize biogas utilization and energy recovery to produce heat, steam and power. The enhanced appearance will complement the existing neighborhood.

MWH Constructors and Webcor, a joint venture, serve as the construction manager/general contractor on the $939 million BDFP. Colorado-based MWH Constructors (MWH) is a leading global construction firm focused on water and energy and Webcor is a San Francisco-headquartered general and specialty contractor with decades of experience building in the city. The JV team was developed to optimize each of the companies experience to best serve the SFPUC and the Project needs.
