Leakage can attribute to a large percentage of your non-revenue water (NRW) and has a direct cost to the operation of a system. It can also affect the water quality rating, damage infrastructure and prematurely deteriorate your assets.
Our leak detection services include acoustic leak detection, ground survey, correlation, noise logging, minimum night flow (MNF) monitoring, water audits, water balance, trunk main leak detection and non-revenue water (NRW) investigations.
Detection Services continues to undertake the largest volume of leak detection surveys in Australasia annually and are engaged in multiple long term leakage management programs, providing specialist leak detection services to more than 100 water authorities across Australia, New Zealand and Asia-Pacific.
To date Detection Services has completed over 210,000 kms of AGS (Acoustic Leak Detection) surveys.
For water mains of less than 300mm diameter, typical acoustic leak detection programmes are generally the most cost effective and efficient method of managing your reticulation leakage.
This process involves skilled and experienced leakage technicians acoustically testing all of your reticulation assets, these include meters, stop taps, hydrants, valves, air valves etc for evidence of leakage.
This is followed by DCL – digital correlation logging, noise correlation and noise logging to confirm and localise the leak, which is then confirmed by ground acoustics.
This staged approach maximises results and enhances accuracy giving pinpoint leakage reporting accuracy.
