Mathoura Water Treatment Plant Upgrade
A regional water treatment plant running on an obsolete PLC, with site drawings that no longer matched reality. Scope redrew it, rewired it, and gave operators control of the plant from any device.
Industry
Water & Wastewater
Location
Mathoura, New South Wales
Duration
Jul 2022 to Dec 2022
Controller
CompactLogix 5380
Scope of Works
The plant needed modern local and remote monitoring and control, with an interface operators could use on a PC or a phone. That meant historising and trending data from the water quality monitors, and giving operators the ability to start and stop the plant remotely.
Underneath the interface was a substantial electrical job. The existing Hitachi PLC had to go, level sensors were needed in every reservoir, and all existing instrumentation had to be brought back to a new controller. The site drawings were well out of date, so the documentation had to be rebuilt before the work could be designed properly.
The Electrical Delivery
Alongside Scope Automation
Scope Automation built the SCADA in Ignition using the Perspective module, so the displays run in a web browser on any device without software to install on each machine. The CompactLogix 5380 communicates to it over Ethernet/IP. Every instrument we wired back to the controller became a live, trended data point on screen.
Key Technologies
From the Job
A Plant You Can Run From Anywhere
Operators can now monitor and control the plant from a PC in the office or a phone in the field, with water quality data trended and historised rather than checked and forgotten.
The CompactLogix 5380 was specified with spare capacity, so the plant can grow without another controller swap. And the site finally has electrical schematics and a P&ID that reflect what is actually installed.
