Sarival Water Reclamation Facility Phase I

Goodyear, AZ

The new Sarival WRF is an MBR treatment facility designed to treat an average daily flow of 4.0 MGD. It supports an existing fully built-out regional WRF by accommodating both current loads and future growth. The MBR treatment process is followed by chlorination to meet Arizona Department of Environmental Quality (ADEQ) Title 18 Class A+ standards for unrestricted reuse. The treatment train includes advanced influent headworks with grit removal and washing, the Closed Loop Reactor (CLR) secondary treatment process, four membrane separation trains, sodium hypochlorite disinfection, chlorine contact basins, and an effluent reclamation pump station. Treated effluent is directed to two discharge locations: the Liberty Aquifer Replenishment Facility—shared with another regional plant—and a local irrigation district canal.

PACE designed a utility service and electrical distribution system to power and control the WRF, including main switchgear, motor control centers (MCCs), and a standby generator system for reliable plant operation. Our design also included -a plant-wide control system architecture with a fiber optic ring network to provide high-speed, resilient communications. All building and site lighting systems comply with applicable standards, including lighting in hazardous locations. Our team provided engineering support during the construction of these electrical components, including submittal review, RFI responses, and field coordination.
