The goal of this project was to move raw water from the Central Arizona Project (CAP) canal located by the Union Hills Water Treatment Plant (UHWTP) into the Cave Creek Water Reclamation Plant (CCWRP) delivery system.
The CCWRP supplies irrigation water to golf courses, parks, and community centers. While it has been offline for the past several years, users have been provided potable water in lieu of the usual reclaimed water intended to maintain their facilities. The City elected to replace the potable water with raw water to fulfill their irrigation water delivery obligations in a more economical way. Working with the City of Phoenix, Carollo, and Kiewit — Entellus led the design and construction efforts to provide the best solution while considering the risks, infrastructure required, water quality, and overall life cycle costs. Alternatives considering pipe alignments, site selection, facilities and equipment, the associated costs, and potential risks were also studied.
The project consists of a new nine million gallons per day (MGD) pumping station containing civil, mechanical, structural, electrical, and instrumentation improvements, a mechanical filter, and chemical feed extended from an existing disinfection system to control Quagga mussel growth. In addition to the new pumping station, this project includes approximately 5,000 feet of new 24-inch waterline which required a bridge crossing of the CAP Canal, a tunneled (directionally-drilled) intersection crossing at Deer Valley Road and Cave Creek Road, and a connection to the existing reclaimed water reservoir at the Cave Creek WRP.
