The treatment facility needed to modernize aging controls while maintaining continuity of water production. The work covered Allen-Bradley PLC logic, SCADA communications, instrumentation mapping, alarm rationalization, and redesigned HMI screens that help operators diagnose process conditions more quickly.
Key highlights
Phased modernization: Structured migration activities around live plant constraints to reduce operational interruption during commissioning.
Controls integration: Integrated Rockwell Allen-Bradley controllers, field instrumentation, and supervisory communications into a maintainable architecture.
Operator-centered HMI: Reorganized graphics and process navigation around abnormal-condition detection and faster fault response.
Commissioning support: Validated I/O, control sequences, alarms, and interlocks with clear test records for plant handover.
Project Impact
The upgraded controls improved plant visibility, reduced the time needed to isolate process faults, and provided a cleaner foundation for future treatment-capacity and instrumentation expansions.
