At Wizard Leak Detection, we remain committed to keeping our clients informed about the latest advancements in water management technology. Water leaks can result in significant water loss and infrastructure damage if not identified early. In a major step forward, Water Corporation has deployed an advanced leak detection system across Perth’s CBD. Powered by cutting-edge technology from Perth-based Terra15 Technologies, this initiative is transforming how water leaks are managed—boosting efficiency and conserving valuable resources.
The system spans a 30km network of fibre-optic cables embedded with distributed acoustic sensing technology. It converts existing telecommunications fibre into an extensive acoustic detection grid capable of pinpointing water leaks before they escalate into serious failures.
By sending laser light through the cable, the system identifies disturbances caused by vibrations or sound. It is calibrated to detect the unique acoustic signature of water escaping from pressurised pipes. This proactive monitoring enables Water Corporation to intervene before minor issues develop into costly bursts, reducing water loss, operational costs & service disruptions.
Beyond leak detection in Perth, the technology is sensitive enough to register background vibrations such as foot traffic, roadworks, tampering, or even seismic activity. According to Evan Hambleton, General Manager of Assets Planning and Delivery at Water Corporation, the system is significantly improving the resilience of Perth’s CBD water infrastructure. It also contributes to reducing reactive repair costs, which totalled $12.5 million in the 2022–2023 financial year.
Despite ongoing upgrades, leakage remains a challenge due to the presence of ageing cast iron pipes—some over a century old. The use of fibre-optic cables as thousands of real-time vibration sensors allows engineers to monitor pipeline condition continuously and take swift action when anomalies are detected.
This technology forms part of Water Corporation’s broader investment of $184.7 million into Perth’s metropolitan water network for the 2023–2024 financial year. Key initiatives include a $10 million project to replace ageing water mains around Kaarta Gar-up (Mount Eliza) reservoir in Kings Park under the Pipes for Perth programme.
