City of Davis Recycled Water Program

City of Davis Recycled Water Program

The City of Davis Recycled Water Program (Proposed Project) is primarily located approximately 1.5 miles northeast of the City of Davis in eastern Yolo County, north of I-80 and west of the Yolo Bypass, at the City of Davis Wastewater Treatment Plant (WWTP) and the immediately adjacent Yolo County Central Landfill (YCCL). The City recently implemented the Davis Wastewater Treatment Plant Secondary and Tertiary Improvements Project which upgraded the treatment processes at the WWTP to replace a pond and overland flow treatment system with a conventional activated sludge process and advanced tertiary treatment system. With the secondary and tertiary treatment system upgrades now complete, a significant portion of treated wastewater that was historically lost to evaporation through the use of the overland flow system and aerated and oxidation ponds has now been reclaimed through the plant upgrades and cessation of the former treatment process. As discussed in the Near-Term Recycled Water Master Plan (West Yost Associates. October 2018.), the amount of this salvaged water, or water saved from loss by evaporation, is approximately 1.8 Million Gallons per Day (MGD) as an annual average, or 2,016 acre-feet (af) per year (afy). The City proposes to put this Saved Water to beneficial use through approval of enrollment under the Statewide General Order Water Reclamation Requirements for Recycled Water Use (Order WQ 2016-0068-DWQ). The City would be the recycled water producer, distributor, and Recycled Water Program Administrator that supplies Saved Water to the WWTP, the 160-acre OFA located east of the WWTP, the YCCL, the Davis Restoration Wetlands, and for city tree irrigation.
