| Objectives | The Discharger owns and operates a water treatment plant (WTP), which provides 3 to 15 million gallons per day (mgd) of treated water from Magalia Reservoir for domestic and agricultural purposes to a population of approximately 26,000. The facility is located in Section 25 and 36, Township 23 North, and Range 3 East of the Mt. Diablo Base Line and Meridian on Assessors Parcel No. 065-260-008. Treated wastewater is discharged at latitude 39 degree, 48 min, and 59 sec and longitude 121 degree, 34 min, and 50 sec to Magalia Reservoir, a man made impoundment on Little Butte Creek, both waters of the United States. The WTP lies within the Upper Butte Creek Hydrologic Unit, as depicted on interagency hydrologic maps prepared by the Department of Water Resources in August 1986. The WTP chlorinates raw water from Magalia Reservoir and the nadds alum, alumninum chlorohydrate, and a polymer ahead of three upflow clarifiers. Clarified water is directed to six downflow, multi media pressure filters and then to a 650,000 gallon, baffled clearwell, which provides limited storage and contact time for proper disinfection. Zinc orthophosphate is added to treated water for corrosion control within the distributing system. |
