Award-Winning Water Treatment Plant Uses PlantPAx™ Control Systems To Double Water Treatment Capacity While Maintaining Staff Levels

By Rockwell Automation

The City of Plano's main challenge was to make the necessary improvements to increase plant capacity to 2.44 MGD within the City's budget constraints and a tight schedule.

The plant expansion would require replacement of existing control systems with modern process controls, new motor controls, instruments and value actuators, which would use networked communications whenever possible. Process automation controls would also monitor the processes for nitrification to help meet environmental regulations.

The existing plant had very little instrumentation for process control and therefore very little data collection, historical trending and monitoring capabilities. The City wanted to improve its process control capabilities and reduce the time and work involved in these tasks, while maintaining existing staff levels.
