Southeast Treatment Plant (SEP) Biosolids Digester Facility Project

Project Vision

San Francisco, CA

The Biosolids Digester Facilities Project (BDFP) was developed to modernize and replace aging solids treatment infrastructure at the Southeast Treatment Plant, ensuring reliable and sustainable wastewater operations for future generations. The project will transform the facility through the implementation of modern treatment technologies that improve biosolids quality, maximize biogas utilization, enhance odor control, and support resource recovery efforts. In addition to operational improvements, the project is designed to create environmental, economic, and community benefits through workforce development opportunities, neighborhood enhancements, and long-term investment in critical public infrastructure.

JBR Partners, Inc. provided partnering and stakeholder engagement support to facilitate collaboration among project owners, contractors, consultants, and community stakeholders. Through structured partnering sessions, issue resolution discussions, and ongoing communication, the team helped strengthen relationships, improve coordination, and support successful project delivery. By fostering open communication and alignment among stakeholders, the partnering process helped address challenges proactively and maintain focus on shared project goals throughout planning, design, and construction.
