Biosolids Digesters Facilities

Overview

As part of the Sewer System Improvement Program (SSIP), we are investing over $2 billion to upgrade and modernize the aging Southeast Treatment Plant (SEP) to reduce odors, be better prepared for earthquakes and sea level rise, and ensure operational redundancy and efficiency. When complete, the city’s largest wastewater pollution treatment plant will be transformed into a resource recovery facility that smells better, looks better and works better.
