Document Description
The Riviera West Mutual Water Company (RWMWC) is proposing to permanently install a sprinkler irrigation system for the disposal of filter backwash water generated from the flushing of their filter tanks. Their current Use Permit, approved in 1995, allowed for the disposal of filter backwash water into Clear Lake. Several years ago the water plant operators stopped discharging the filter backwash water into Clear Lake and began sprinkler irrigating the water onto and adjoining lot, APN 044-340-24, in violation of their Waste Discharge Requirements (WDR's) issued by the California State Water Resources Control Board. They are currently discharging this sprinkle water without valid WDR's are being fined by the State. This project proposal also includes construction of a 30' diameter by 18' high water clarifier tank on a vacant parcel abutting the existing water company. Also proposed is the construction of a 7' diameter by 7' high water contact clarifier tank within the existing water company facility until funds become available to purchase the larger 30' diameter by 18' high tank.
