Zone 1 Reservoir Project

Zone 1 Reservoir Project

Final Project Map

Irvine Ranch Water District will be installing a second, smaller reservoir at Sand Canyon Avenue and Elysian to increase water storage capacity and create a necessary backup supply of drinking water that will ensure uninterrupted service to Irvine residents. The site is owned and operated by IRWD and contains several drinking-water-related facilities, including a large reservoir.

The project has been designed to maintain the visual character of the neighborhood and to minimize the visual impact of the new reservoir. A graded slope, extensive landscaping and other features have been incorporated into the design to help screen the new reservoir from view. Construction is scheduled to begin in late September, and will take approximately 18 months to complete.

Work hours: 8:30 a.m. to 5 p.m. Monday through Friday.
