Mark is a specialist and his many years in the industry have confirmed that no single technology will solve every problem. Environmental conditions also play a big part as acoustic equipment requires minimal background noise to ensure leaks can be sounded correctly… read more

Mark always assesses new equipment as it comes on the market to decide whether it is right for his business.
Recently, we added the latest non-destructive method of leak detection to our services. This tried and tested method can be used to locate leaks in distribution networks for both gas and water. It can also be used for heating systems, pipelines in buildings, pressurised communication cables, gas-filled high voltage power lines and landfill sites that have been sealed with a double layer of membrane.

It is an ideal detection method to test for leaks in industrial products such as pipes, pumps and engine blocks.
Leaks are detected using a mixture of 95 per cent nitrogen (carrier gas) and 5 per cent hydrogen, which is fed into the pipelines or other equipment and/or products being tested. The highly sensitive, specialised sensor detects the hydrogen as it escapes through the leak.

This is a very safe method as only 5 per cent hydrogen is used: the gas is not combustible as per ISO 10156 because nitrogen is used as the carrier gas. This method is non-toxic so it can be used in drinking water distribution networks and it is non-corrosive.

Tracer gas is cheap and easy to purchase from dealers that carry technical and welding gas. It is environmentally neutral and penetrates all cover layers such as concrete, bitumen and other sealers. Tracer gas always takes the shortest route from the leak to the surface. 


Surveys are conducted using leak noise loggers to detect leaks when the system is quiet. Leaks can be located on longer pipelines and information logged using PC based leak correlators.

We can carry out:

  • ALD surveys and water audits
  • Data gathering for hydraulic modelling
  • Surveys of Sewer Rising Mains
  • Investigations of Trunk Distribution Mains
  • Investigations of bore field water loss
  • Utility Mapping
  • Reporting on the condition of valves and mains
  • Investigations for unauthorised water use
  • Investigations for residential and commercial water loss.

Various methods and data processes are an integral part of a full “water audit”. At the end of an investigation, we produce a technical report detailing the water loss. Satellite phones are used to communicate anywhere in Australia.
