South Mesquite Regional Wastewater Treatment Plants SCADA Improvements


North Texas Municipal Water District

South Mesquite RWWTP utilized in Plant radio system to communicate minimal SCADA information. The project upgraded the SCADA system for the entire Plant. GAI served as the prime consultant on this job and preformed the electrical distribution and controls as well as the instrumentation and controls engineering.

This Project included: design of a full fiber optic cable backbone ring network throughout the Plant; new PLCs; connecting additional PLCs to the network; replacing the existing graphical user interface, Lookout, with FactoryTalk; replacing the data concentrator used to communicate with three lift stations; and extending the Plant overhead distribution system by providing new poles, overhead line, and reclosers. For locations with existing PLC, existing communication devices will be demolished and wired to the new fiber optic network. For locations that require a new PLC, this project provided control power and instrumentation wiring for monitoring and control.
