Jomax Water Reclamation Facility
Peoria, Arizona
DLT&V provided the electrical and I&C design for the Phase I and II construction of a new $14.3 million water reclamation facility for the Shea Homes Pleasant Point development, in Peoria, Arizona. The plant’s 12,470-volt primary power distribution system consists of loop fed distribution switches connected to dual 12,470/480 transformer substations, with main-tie-main switchgear for redundancy, feeding 480-volt motor control centers and load centers. A 12,470-volt generator provides standby power through a transfer switch connected to the main service entrance equipment. We designed the plant control systems for unattended operation. Packaged systems and Modicon Quantum PLCs communicating to an Intellution iFIX SCADA system control the processes. The main plant process areas consist of the headworks influent pump station, screening
and grit removal, intermittent cycle reactor, aeration blowers, RAS/WAS pump station, solids handling facility with belt filter presses, traveling bridge filters, UV disinfection, and effluent pump station. Broadband wide-area network connections allow the City to remotely monitor the facility over their SCADA system. DLT&V also provided system integration programming services during construction, along with shop drawing review, construction observations, and plant startup services.
