Design of Two New Reservoirs including View Analysis

Psomas was retained to design a new recycled water reservoir and domestic water reservoir for the Portola Hills area of the City of Irvine. Both reservoirs were designed as partially buried, pre-stressed concrete circular tanks.

The domestic reservoir includes a reservoir management system designed to circulate stored water and provide additional disinfection when needed to maintain water quality. Chlorine and ammonia residual analyzers, bulk sodium hypochlorite and ammonia storage facilities, and chemical metering and injection were located within a masonry block building.

The team conducted site studies including computer generated grading studies, view analysis studies and earthwork estimates.
