Fiber optic cables already in the ground could become an early warning system for leaking water pipes through a new technology being trialled in Melbourne.
Intelligent Water Networks (IWN) is a body that fuels innovation in the water industry on behalf of its members across the sector. It is funding the trial as part of a consortium that includes FiberSense, who have innovated the technology, Greater Western Water, who own the infrastructure, and Veolia.
Together, they are testing the theory that they can quickly find and pinpoint places where water is being lost from the network through bursts, leaks, strikes or construction activities by testing the system in the GWW water supply network.
It works by using the existing telecommunications fiber as a massive array of ultra-precise vibration sensors. They can detect strikes or damage – even from unplanned or rogue activities – and the vibrations caused by leaks big and small. Any detected issues trigger real-time alerts to inform swift action.
The technology does not impact on the core performance of either the water or data networks as it does not physically change any infrastructure.
IWN program director Jason Cotton said their aim was to enhance intelligence in the water, sewer, and recycled water networks to enable proactive operational and strategic decisions from real-time data.
“We are eager to explore the capabilities provided by the FiberSense suite, and how we can work together to save substantial amounts of water across the network by early detection and repair of leaks and bursts,” he said.
FiberSense founder and chief executive Dr Mark Englund said the company had seen an increased demand for innovative and high-tech solutions to address growing environmental challenges such as water distribution integrity.
“We are delighted to be collaborating with IWN and GWW as well as Veolia – a group of organisations at the global forefront of managing water assets and addressing the challenges of limiting non-revenue water loss,” he said.
“The trial in Melbourne follows similar projects with major water companies overseas. FiberSense technology represents a significant stride towards minimising water wastage and maximising the efficiency of water distribution systems.”
Greater Western Water Growth and Infrastructure acting general manager Bri George said addressing network issues could bring big benefits.
“We are always keen to explore innovative technology on early detection of leakage in our water network to assist with minimising water losses. We are looking forward to understanding the outcomes of this trial and how it could save water. That means better environmental and financial outcomes for customers and communities,” she said.
