Mt Crosby East Bank Water Treatment Plant (WTP) is a significant Seqwater asset, supplying treated water to residents, businesses and industry in South East Queensland.
The upgrade project consisted of the design & construction of a new Programmable Logic Controller (PLC) and Supervisory Control And Data Acquisition (SCADA) system to eventually replace the existing legacy Honeywell/Experion system and equipment which is nearing the end of its life cycle. The new chemical sludge handling PLC, incorporates hot standby Siemens S7400H processors utilising a Media Redundancy Protocol (MRP) remote Input/Output (RIO) network allowing simultaneous PLC and network failure without process interruption.
The new PLC is located in the Mt Crosby East Bank control room with a new fibre optic cable network installed currently connecting it to the new alum dosing RIO panel and the sedimentation basin 2 RIO panel. In the future this PLC and fibre optic cable network has the capacity to connect all chemical systems and sludge RIO panels installed as part of future upgrade projects.
The Project is the first stage of the MCS project which is an organisation wide upgrade of monitoring and control systems and consists of a whole portfolio of projects.
