Water Mains Leak Detection Methods

Acoustic Listening Devices

Acoustic leak detection technology uses a highly sensitive and accurate microphone which is able to detect the sound of leaking water underground.

Leak Noise Correlators

Correlation sensors are placed on the water pipe on either side of the suspected leak, and then they send out signals that bounce off the leak’s location.

The technology then uses a mathematical formula to identify where the leak is. 

Cat & Genny

Cat and Gennys are used to identify the exact location of underground pipes. 

Cat and Genny play a role in locating water pipes underground before tracer gases and acoustics are used.

Tracer Gas Leak Testing

Tracer gases are made up of 5% Hydrogen and 95% Nitrogen. The compressed gas is introduced into the water main supply pipe and escapes at the leak locating.

The gas rises to the surfaces and is detected using tracer gas sensor.
