TasWater has implemented a high-tech leakage management system that can detect the sound of leaks. 

Around 40 ‘Zonescan’ devices have been installed to listen for leaks within TasWater’s systems and pinpoint them on a map.

The technology should help reduce the amount of unaccounted for water, which was identified in the State of the Industry Report as an area in need of improvement.

TasWater Acting Department Manager Asset Strategy and Performance Matt Jordan said the new system is being rolled out across the state.

“They help us identify leaks, some of which that we know about but cannot find,” Mr Jordan said.

“This technology also helps us find leaks that aren’t visible and would have previously gone

undetected.”

Traditionally, leaks come to the attention of TasWater through the customers calling and

reporting them to the call centre, and staff out in the field who come across them.

The new technology should allow the authority to take a more proactive approach to leak detection, as and when they occur.

“The process of active leakage control involves teams of leakage detection staff sweeping an area using sounding techniques to find leaks, this is possible through technology such as the Zonescans,” Mr Jordan said.

“If sweeping is carried out frequently, then leaks can be kept at a minimum.”

“We are currently targeting areas which have a higher number of leaks and bursts, before we roll out this initiative more broadly.”
