| Objectives | The Discharger owns and operates the WWTF that provides sewerage service to the City of Merced. The WWTF consists of headworks, a septage receiving area, two primary clarifiers, three activated sludge basins with three internal separate anoxic denitrification basins, three secondary clarifiers, and chlorination and dechlorination units and the Land Application Area and Wildlife Management Area, which are described in more detail below. Sludge is thickened, anaerobically digested, and then dried in six unlined sludge-drying beds. Due to recent aeration improvements and incorporation of the SymBio process (nitrification/denitrification), the Facility now can process a dry weather monthly average flow of 11.5 mgd. |
