Document Description
The proposed project would provide full secondary treatment for all effluent discharged through the WWTP ocean outfall and provide tertiary filtration capacity equivalent to the peak season dry weather flow (PSDWF) of 1.5 million gallons per day (mgd). The tertiary filtered effluent would meet Title 22 standards for disinfected secondary-23 recycled water and as such could be used for limited beneficial uses. The proposed project would accommodate future improvements to produce disinfected tertiary recycled water for unrestricted use in accordance with Title 22 standards. The City of Morro Bat and Cayucos Sanitary District (collectively "MBCSD") anticipated reclaimed water end uses would include, but not be limited to, treatment process applications onsite at the WWTP, landscape irrigation around the perimeter of the WWTP, and offsite municipal and industrial (M&I) applications such as dust control, soil compaction, street cleaning, municipal landscape irrigation, and agricultural. 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.
