Document Description
The District proposed Project includes construction of a 3.7-million-gallon reservoir adjacent to IRWD's existing 15-MG Zone 1 reservoir to serve existing District 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 above ground 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, drainpipe, valve vault to house the inlet and outlet piping. One butterfly valve 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. Additional site improvements will include new retaining walls, a relocated access road, a concrete gutter, and a motorized double-swing access gate at the site entry.
