SAFEgroup Automation (SGA) in Australia was engaged by Unitywater to design and install 8 multi-parameter water quality monitoring systems utilising our ultra low powered M-Node digital water quality sensors.

This project comes as part of Unitywater’s Digital Neighbourhood program which aims to transform their water and sewerage network. This will result in an intelligent data platform where advanced analytics can be used to provide data-driven decision-making, that will ultimately benefit Unitywater and its customers. Previous projects under this program include the installation of smart metering and leak detection in the water reticulation network.

Limited by a lack of site power and communications, the battery powered MetriNet water quality monitoring system from ATi was an ideal fit for the task and was installed alongside the Metasphere Point Orange RTU with NB IoT cellular communications. This ultra low power system communicates with a high level of accuracy and resolution back to Metasphere’s Palette cloud platform. The RTU is also capable of communicating via DNP3 protocol directly to Unitywater’s SCADA system.

This project will play a key role in allowing Unitywater to understand the disinfection behaviour of the water reticulation network and understand the efficiency and effectiveness of the chlorine levels in next to real-time. This project is just another step in ensuring the delivery of consistent high-quality water to customers.

The MetriNet smart water quality monotoring system was required by Unitywater to measure and monitor the following water quality parameters:

• Total Chlorine
• Combined Chlorine
• Free Chlorine
• pH
• ORP
• Conductivity
• Pressure
