Document Description
IRWD proposes the conversion of the northern section of the Irvine Lake Pipeline (ILP) from an untreated water system to a recycled water system. The project would include construction of a 2.4 million gallon recycled water reservoir on 2.7 acres at 1802 East Santiago Canyon Road, Orange; conversion of an existing Zone A-C booster pump station at the Rattlesnake Complex located north of Portola Parkway between Jeffrey Rd. and Culver Dr. in Irvine to a Zone A-C+ booster pump station; reconfiguration of the Orchard Hills Facility located at 10570 1/2 Woody Knoll, Irvine, to serve as a back-up source of recycled water; and construction of a 20-inch Zone C+ pipeline along a portion of Jamboree Road from the Baker Raw Water Pump Station northerly to the intersection with Santiago Canyon Road and a 10 inch pipeline along a portion of Santiago Canyon Road.
