Document Description
The proposed project would upgrade the Morro Bay-Cayucos Wastewater Treatment Plant (WWTP) to tertiary treatment and would enable it to discharge 2.0 mgd of tertiary treated effluent to the ocean. The upgrade involves the construction of a new treatment plant, including the following facilities: administrative building, maintenance building, influent pumping station, screening facility, oxidation ditches, RAS/WAS pumping station, tertiary filters, secondary clarifiers, solids handling facilities, chlorination building, hazardous waste station, and chlorine contact basin. Once the new treatment plant is constructed and brought online, the existing treatment plant would be demolished. The existing onsite composting program at the WWTP would be discontinued.
