iDROLOC is a leak detection system which injects a tracer gas (Helium) into the water main to detect leaks without interruption to the service. It can be applied to large diameter mains, smaller distribution pipes, or house hold connections within an urban area.
iDROLOC can detect very small leaks, even in large diameter pipes and offers an accurate and efficient alternative to conventional acoustic methods.
As a pipe condition assessment tool iDroloc can be used to detect minor leaks in joints to prevent future leakage.
iDroloc can also be used to commission newly constructed pipework. Helium gas and compressed air can be used to pressure test the pipework and then identify any leaks if detected.
The principle of the system is that Helium is introduced into the water flow. Any leaks in the pipework are identified when the gas/water escapes through and leaks in the pipework. The water carries the Helium out of the pipe and as a gas lighter than air, it rises to the surface. The concentration of Helium in the atmosphere is very small, allowing detection at ground level.
- No disruption to customers, as the work is carried out on the live network
- Leaks can be located on areas that have a high percentage of plastic or non-metallic pipework - not affected by sounds or vibrations
- Fast and accurate in large pipes, where standard methods may not be reliable
- Most effective method for non-metallic pipes and/or low network pressures
Will any customers be affected?
Some customers near the helium insertion point may experience 'air in supply', we recommend warning customers to avoid any unwanted calls.
Is this technique DWI approved?
Yes, this technique can be used on a live portable water network.
Do the holes get filled following the survey work?
Yes, all the holes are filled using a highway approved material.
What is the accuracy of the technique?
Our trained operators will expect to locate the leak within 2m, and on most occasions within that distance.
