How can you do this?
Why we acted
The shopping centre suspected it might have a leak when a staff member noticed an unusual amount of water flowing through a loading dock storm water drain.
This triggered an investigation by the shopping centre, with help from Water Corporation.

How we did it
As one of the largest shopping centres in Perth finding a leak across 70,000 square metres of retail area was not going to be easy.
A data logger installed on the meter confirmed s leak of approximately 40 litres per minutes, which is the equivalent of 21,000 kilolitres per year, so managers were keen to locate and repair the leak as soon as possible.
To locate the leak, the centre engaged a licensed plumber to install isolation valves and pulse capable sub-meters. Using the data logging technology the centre could view their water consumption on a near real time basis to isolate the area of the centre with the leak.
Once identified, ground penetrating radar, acoustic listening equipment and pipe locating equipment was used to pinpoint the exact location. The leak was eventually discovered in a pipe bend 3 metres below the ground in a loading dock.
