Document Description
The proposed project would upgrade the Morro Bay-Cayucos Wastewater Treatment Plant (WWTP) to tertiary treatment and would enable it to discharge 1.5 mgd of tertiary treated effluent to the ocean. The upgrade involves the construction of new oxidation ditches, cloth-media disk filters, a secondary clarifier, centrifuges, a gravity belt thickener, and a chlorine contact basin; full rehabilitation of Digester N. 1 and 2; and improvements to other support facilities. In addition, the following structures would be retired: the existing chlorine contact basin, trickling filters, solids contact basin, Digester No. 1, and primary clarifiers. The existing onsite composing program at the WWTP would remain unchanged as a result of the proposed project.
