Greenway Water Treatment Plant

    The Greenway Water Treatment Plant for the City of Peoria in Arizona was fast tracked. The integrator that was originally hired by the general contractor was kicked off the project for failure to do any work. Their bond was enforced and bonding company went in search of a new integrator. We were awarded the contract under the condition that we could still make the schedule. The system included Modicon Quantum PLC's and with Modbus Plus Repeaters with dual fiber ring for communications. Even some of the RIO was fiber linked. The SCADA servers were redundant using Intellution iFIX for the HMI. Two of the PC's were touch- screen panel mount PC's.
We had to take incomplete information that we could get from the general contractor that they had received from the previous integrator and design panels, design communications, build panels, write PLC program, and create HMI screens in time for the Factory Acceptance Test that was only five months away.
    There were many 18 hour days over the next few months, but we completed everything on schedule. I also feel that I was able to create some of the best HMI screen I have ever completed to date. Here are some of the screen shots: Main Menu, Bar Screen, Ozone Contactor, Filter, Sludge Thickener, Polymer & Alum . We mocked up the entire system in our shop complete with fiber optic connections for the Factory Acceptance Test. I was also responsible for the communications on this project. I have included one close-up photo of a communication side panel.

The system has Modicon Quantum PLC's, Modbus Plus communications, Fiber Optics, and Intellution iFIX.
