4. City of Lake Charles, Water Division

Engineer: D. W. Jessen & Associates

Served as general contractor, instrumentation system supplier and application engineer for a city-wide telemetry and control system for the production of drinking water. This installation replaced existing hardwired and tone type telemetry with an automated control system to provide expandability, precise historical logging and reporting, and greater reliability. One Modicon Quantum PLC and seven Modicon Compact 984 RTUs communicate across Lake Charles on a Modbus network spanning both telephone and radio frequency connections. Wonderware Intouch SCADA workstations provide the operators a window into the process. Commissioned approximately 100 analog control loops at 6 sites associated with control and monitoring of the water plant processes. Replaced Bristol Babcock solid state filter control system and MMI interface with Wonderware touchscreen and Modicon PLC based system, automating backwash sequence for cleaning water filters and custom reports for record keeping.
