New research shows how a special tool called a noise logger can detect leaks accurately and efficiently, before major roadwork is required.
The world is approaching a water crisis. According to the International Water Management Institute, 33 per cent of the world’s population will experience water scarcity by 2025.
One main cause is leaks. Twenty to 30 per cent of treated water is lost in systems because of this simple and fixable problem.
Repairs need to be as precise as possible because excavation and resurfacing is a costly undertaking. Digging up more than one location, or more area than is needed for the repair, can lead to a problematic domino effect including traffic disruption, commuter frustration and loss of business.
Meanwhile, there are major public health risks associated with contaminants entering the water system through holes in pipes.
Luckily, researchers from Concordia University in Montreal have an innovative solution. In an article recently published by the American Society of Civil Engineers, Tarek Zayed, professor in the Department of Building, Civil and Environmental Engineering, shows how a special tool called a noise logger can detect leaks accurately and efficiently, before major roadwork is required.
