WATER LEAK DETECTION SERVICES
Established for over 10 years, we at H20 have a wealth of experience and expertise in identifying, locating and repairing underground water leaks nationwide. We have undertaken and successfully completed projects for many well known organisations such as:
H.M Prison Service
London Borough of Hammersmith and Fulham Council
London Borough of Lewisham Council
B.P Service Stations
Cannons Health and Fitness
And many more.
Water leakage detection is fast becoming a larger part of our business.
Water Leakage Detection
How do we do it?
There are various water leakage detection techniques dependant on site conditions, for example:-
Electronic listening equipment amplifies the sound given off by a water leak, our team use their years of experience and expertise to accurately pinpoint the leak and mark off in order for repairs, to be swiftly completed by our repair team, most water leak detection starts with this method.
L.N.C Leak Noise Correlation
This clever piece of kit uses two sensors placed at each end of the suspected water leakage area, it is then calibrated according to supply pipe size, material and distance between the two sensors. Placed on the water supply pipe or valves the system will then locate the noise made by the leaking water and visually display the water leak on the screen calculating the exact point of the water leak. Our team then mark the point of the leak for repair by our team. Upon compeltion further water leak detection is carried out to confirm all water leaks detected are repaired.
Water leak detection tracer gas techniques
In some instances according to site and ground conditions we have to inject gas (95% nitrogen 5% hydrogen) into the main, upon completion a sensitive gas detector is then passed over the leaking water main and as the gas escapes from the water leak area the detector registers the leaking gas, we then mark down the leak area for our repair team. Further leak detection is carried out to ensure all water leaks detected are repaired.
Water leak repairs
Upon completion of the water leakage detection a report containing specification and cost or repairs is sent to the client electronically, we will in most instances quantify the water losses and report the monetary value.
Upon receipt of approval we excavate, repair and reinstate all surfaces disturbed, sometimes further leak detection may be required if futther water leaks are suspected.CONTACT US
