The San Francisco Public Utilities Commission’s Biosolids Digester Facilities Project Earns Envision Platinum Award

The Biosolids Digester Facilities Project is located at the Southeast Treatment Plant, San Francisco’s largest wastewater treatment plant.

The SFPUC is investing over $3 billion to upgrade and modernize the aging Southeast Treatment Plant (SEP) as part of a more extensive Sewer System Improvement Program (SSIP). Once the upgrades are finished, SEP will reliably work better, smell better, and be a more significant community asset. The SFPUC is also upgrading the SEP for earthquake preparedness, sea-level rise, and operational efficiency. In addition, the work will reduce odors and improve the quality of life for nearby residents and employees.

The Biosolids Digester Facilities Project (BDFP) is an essential component of the larger SEP upgrade. The BDFP project will replace and relocate the existing (and outdated) solids treatment facilities with more reliable, efficient, and modern technologies and facilities. This project will help transform the SEP into a modern resource-recovery facility, allow the SFPUC to meet its levels-of-service goals, and be an attractive place to work and visit.

“Achieving Envision Platinum is a major accomplishment, and it reflects the hard work of so many people at the SFPUC and in this community,” SFPUC General Manager Dennis Herrera said. “Environmental justice is at the forefront of our work, and this award underscores our commitment to a sustainable future, including the health and wellbeing of the communities in which we operate.”
