The City of Tempe, Arizona, needed to make improvements to their existing Kyrene Water Reclamation Facility to add capacity, but also (and more importantly) to improve the quality of the treated effluent. Improvements were made to allow the high-quality reclaimed water to be provided to various end users, such as the Salt River Project (SRP), for cooling tower use. Tempe selected PCL as its Construction Manager at Risk to make the needed improvements to the plant. This project was a 9 MGD expansion of the existing conventional water reclamation plant to a state-of-the-art membrane and ultraviolet technology plant.
The project included modifications to the existing influent pump station, a new screenings and grit removal facility, two new aeration basins, modifications to the existing aeration basins, reconfiguration of the existing secondary clarifiers to membrane basins, a new blower building, construction of a new ultraviolet disinfection and reclaimed water pump station, a new odor-control system, and significant underground utility work.
