Built in 1952, the Southeast Water Pollution Control Plant (SEP) is the City’s largest wastewater treatment facility, handling nearly 80% of San Francisco's combined stormwater and wastewater every year. The purpose of the SEP secondary clarifiers (SEP 230) is to separate activated sludge in the mixed liquor from the treated wastewater. Return activated sludge is returned to the aeration tanks and waste activated sludge is transferred to the solids handling facilities. The sedimentation tanks consist of sixteen reinforced concrete circular tanks which are divided into two groups of eight, designated as the North and South clarifiers by their relative position on the plant site. Equipment included in SEP 230 consists of diffusers to mix the flow in the mixed liquor channels, gates and valves to control flow and sludge/scum collection equipment in the clarifiers.
The Local Business Enterprise subconsulting and subcontracting participation requirements for this Project are 20.00% for Design Services and 20.00% for Construction Services, respectively.
