ACOUSTIC WATER LEAK DETECTION

4579988980

Some reasons to suspect a water leak:

  • Your water bill is substantially higher than usual
  • Drop in water pressure
  • The Council has sent you a high water usage notification
  • You have a section of concrete/pavers that’s always damp or mouldy
  • An area of your grass grows much faster or is much greener than the rest
  • An area of your grass or garden is constantly wet or soggy
  • When you turn off all taps the water meter is still spinning
  • Retaining walls or brickwork has cracks or movement

When a pressurised water pipe develops a leak the water flows out of it into the surrounding ground at high speed, which causes the pipe and soil to vibrate at the exit point. This sound, or vibration, is transmitted by the pipe and surrounding material where it can be heard with the highly sensitive microphones.

When the section of pipeline with the leak has been preliminary located, or you have decided to walk the surface of the pipe to find the leak, pin pointing the leak can be carried out using our highly skilled and experienced staff.

How to read your water meterElster_water_meter

There are many different water meters used throughout Australia but they can all be read in a similar way. The display panel on your water meter has both black on white as well as white on red figures. The black on white figures represent the consumption in kilolitres.
When reading your consumption for billing purposes the council only reads the black figures.

Overnight Leakage TestComparing-two-meter-readings

If you read your water meter last thing at night and then first thing in the morning without using water during the night you can calculate how much water is being lost through a leakage.
Subtract the previous nights reading from the morning reading.
Example:
3746.310 – 3746.215 = 0.095kl (95 litres)

If you are losingĀ more than 1LĀ of water per hour you should check for dripping taps, faulty toilet cisterns or other leakage.
If more than 10L is being lost per hour then you need us to investigate for a leak.
