TRILITY provides the Operations and Maintenance contracts of a large number of Water assets around Australia including water treatment plants, desalination plants and wastewater treatment and reuse plants. ATSys were engaged to provide the control systems upgrade for two of their SA based water treatment plants. The upgrade involved replacing the legacy PLC5 control system with an up to date equivalent.
ATSys were able to perform the full conversion of logic from the old platform to the new platform and provide detailed bench testing to ensure data integrity. Downtime of the process had to be kept to a minimum and ATSys worked with the cli ent to develop a cutover strategy to ensure this happened. Parallel testing on site with detailed system monitoring and trending provided the confidence that the conversion was successful.
