Sarival Water Reclamation Facility

Goodyear, AZ


The new Sarival WRF will treat an average day flow capacity of 4.0 Million Gallon per Day (MGD) with a maximum day flow capacity of 6.0 MGD and a peak-hour capacity of 10.0 MGD in Phase 1. The facility utilizes a membrane bio-reactor treatment process, followed by chlorination disinfection, to meet Arizona Department of Environmental Quality (ADEQ) Title 18 Class A+ requirements for unrestricted reuse of recycled water. The Phase 1 treatment process consists of an advanced and integrated influent headworks and grit removal and washing system, followed by the advanced Closed Loop Reactor (CLR) secondary treatment process trains, coupled to four (4) membrane separation trains, and followed by the sodium hypochlorite disinfection process / chlorine contact basins and effluent reclamation pump station. At full buildout, the design of the SWRF will provide an average day flow capacity of up to 8.0 MGD with a maximum day capacity of 12.0 MGD. Future phases of the facility will also introduce an advanced bio-solids processing facility to handle solids processing for multiple treatment plants within the regional area. PACE is serving as the Engineer-of-Record for the facility, with the project being delivered through a fixed fee design-build effort with PERC Water.
