Noise Loggers Listen for Leaks

Jun-26-16 The “noise logger” devices can detect underground leaks by their sound with an accuracy of up to 99.5 percent, offering a quick way to find leaks and save water.

Developed by a team from Concordia University, the noise logger system was created with an eye towards saving water as it becomes increasingly scarce. The system is made up of an array of noise logger sensors magnetically attached to different areas of the water network, such as manhole covers or hydrants. The system is activated at night to record the noises throughout the system, allowing the team to analyze the sounds and detect leaks and locate them via mathematical modeling.

Currently, leaks in water systems account for an average loss of up to 30 percent of treated water, with older systems reaching as high as a 50 percent loss.
