Case Study – Gippsland Water – Automated water quality monitoring

Gippsland Water is a regional water corporation responsible for delivering drinking water, managing wastewater, and overseeing nvironmental stewardship across Gippsland, Victoria. The Heyfield Water Treatment Dam is a key component of their East Gippsland operations and an important part of the local water treatment network.

Gippsland Water required additional Aqua Armour modules for deployment at their Heyfield storage pond (approximately 2,800 m²). They also sought the potential for booming installation to secure the modules if needed in the future. Additionally they were wanting real-time water quality data, including water level, temperature, dissolved oxygen, and turbidity.

HydroTerra provided a comprehensive solution to address Gippsland Water’s requirements:

• Aqua Armour Deployment: Modules were installed at Heyfield to prevent and reduce algal growth in the water treatment pond.
• Booming Installation: Booming was installed in 20 m × 20 m cells to prevent Aqua Armour modules from moving during strong winds.
• Telemetered Water Quality Monitoring: Ongoing monitoring was implemented to measure potential fluctuations in water quality, including temperature, dissolved oxygen, turbidity, and chlorophyll. Data are transmitted to the DataStream platform to support improved water storage management at Heyfield.
• Project Management & Data Management: HydroTerra managed the full scope of project planning, site assembly, deployment, and setup of the DataStream platform, ensuring client personnel were trained in system use and monitoring protocols.

• Reduced algal growth at Heyfield pond
• Modules remain secured during strong winds
• Real-time water quality monitoring enables better water storage management
• DataStream provides ongoing visualization, alarms, and reporting
