Russian River Wastewater Treatment Plant Equalization Basin Storage EIR

Russian River Wastewater Treatment Plant Equalization Basin Storage EIR

The proposed project will result in the construction of an earthen equalization basin and ancillary structures. All development would occur entirely within the existing property lines of the Russian River County Sanitation District Wastewater Treatment Plant (WWTP). The equalization basin would provide temporary storage of treated or untreated wastewater at the WWTP during large storm events, periods of high influent flow, during upset conditions of the treatment process at the plant, or when irrigation areas are saturated and unable to receive treated effluent. The proposed equalization basin would measure approximately 250 x 150 feet and include earthen embankments up to 30 feet high. The equalization basin would have a maximum capacity of 4.3 million gallons and require the importation of approximately 24,000 cubic yards of earthen material. A pump station would be included adjacent, or within, the equalization basin to pump the wastewater to the headworks (front end) of the treatment plant as treatment capacity becomes available. Project construction would require relocation of various on-site pipes and utilities, including raw sewage forcemains, recycled water irrigation mains, and tertiary treated water outfall piping.
