Sarival Water Reclamation Facility Phase I

Goodyear, AZ


As a subcontractor to PERC Water, PACE was the Engineer of Record for the design, construction, startup, and commissioning of the new Sarival Water Reclamation Facility (WRF). With the completion of Phase I, the facility can treat an average capacity of 4.0 million gallons per day (MGD) with a maximum capacity of 6.0 MGD. The membrane bioreactor (MBR) treatment process, followed by chlorination disinfection, meets Arizona Department of Environmental Quality (ADEQ) Title 18 Class A+ requirements for unrestricted reuse of recycled water.


Replacing the Sarival Lift Station, the Sarival WRF was designed to fit the 6.1-acre site. The design also accommodated growth projections for the area with future expandability. At full buildout, the facility will provide an average capacity of up to 8.0 MGD with a maximum capacity of 12.0 MGD. Future phases of the facility will introduce an advanced biosolids processing facility to handle solids processing for multiple treatment plants within the regional area.


The final design and initial construction proceeded in parallel to meet the project’s fast-track target completion date. The construction of Phase I was successfully completed within the accelerated delivery schedule of 23 months from the start of the design.


Key Features:

  • MBR treatment process with chlorination disinfection for unrestricted reuse of recycled water
  • Progressive design-build delivery with clear communication process to accelerate feedback and efficient project advancement
  • Accelerated delivery schedule with project duration of 23 months
  • Expandable design footprint to accommodate growth
  • Efficient facility footprint to fit within limited site space
  • Enclosed treatment with modern-style buildings
  • Easy-to-access equipment for maintenance needs and ease of operation
