Hunting Renwick’s water leaks
Technicians are working their way through the streets of Renwick this week to identify leaks in the underground water reticulation system, using acoustic detection equipment.
Detection Solutions contracts manager Neil Scrutton says the process involves putting microphones at either end of a pipe, one at a hydrant and one at a valve, to record sounds in the pipes. ‘‘A leak creates noise,’’ he says. ‘‘The time it takes for the sound to reach one end indicates where the leak is.’’
Technicians identified 60 potential leaks in one day, but phase two of the process would require checking the noise
‘‘Statistically, 60 per cent of leaks are private leaks. ’’
