Document Description
IRWD proposes the construction of a 3.7-million gallon reservoir adjacent to IRWD's existing 15-MG Zone 1 reservoir to serve existing IRWD customers in the Irvine service area. The primary purpose of the project is to construct an additional permanent reservoir to allow for storage reliability and operational flexibility in the zone 1 domestic water system. The project would include construction of an aboveground 3.7-MG pre-stressed circular concrete tank. Proposed reservoir construction and operation would also require installation of tank inlet and outlet piping, overflow piping, drain pipe, valve vault to house the inlet and outlet piping. 1 butterfly valves, and roof hatches to allow for tank access. As part of the project, the reservoir management system will be upgraded to accommodate the new reservoir tank.
