Document Description
AVEK operates and maintains four potable water treatment plants (WTPs) known as the Acton, Eastside, Quartz Hill and Rosamond WTPs located in northeastern Los Angeles County and southeastern Kern County. The proposed project includes new and modified facilities needed to convert the disinfection method used at all four WTPs from chlorination of ozonation and chloramination to reduce disinfection by-products. The facilities proposed at the four WTPs include: facilities to store liquid oxygen and convert liquid oxygen to gaseous oxygen, ozone generation building, ozone contact basins, filters, chlorine contact basin, chemical storage and feed facilities, and modifications to internal access roads. The proposed modifications to the Acton, Eastside, and Rosamond WTPs would not alter the design capacity of these three plants. The proposed retrofit of the Quartz Hill WTP includes additional modifications needed to increase the plant's design capacity from the existing 65 to 90 million gallons per day. Additional improvements proposed for the Quartz Hill WTP include modifications to the flocculation/sedimentation basins and construction of a new washwater recovery basin, and additional storage facilities for alum and sodium hypochlorite.
