The amount of pipe we can test often depends on the experience of the Leak Detector. Team members with many years of experience can test up to 10 miles of pipe a day on a metallic system (Cast Iron/Ductile). Experienced Leak Detectors can test a contact point (Hydrant/Valve) within a minute before moving on to the next one. Leak Detectors can work efficiently because they are trained to hear the specific tone that a leak produces compared to any other number of noises a general environment makes.
Our acoustic listening equipment is highly sensitive and amplifies leaks and other noises which mask leak signals during the day. If we work in city environments, there is often a significant amount of ambient noise. This noise includes airplanes, traffic, mowers, machinery, and most importantly, people using water. It is up to the Leak Detector to determine if night work should be utilized to minimize all other noise to focus on the leak signal.
We have developed a rigorous leak detection methodology. We are confident in our leak location markings if all criteria are met using our available technologies.
After analyzing thousands of previous leaks detected, we asked clients to send us pictures of the remediation. This information has helped us compare our final leak signal detected with the results of the actual leak. We determine the size of the leak by how far the leak signal travels between contact points and the pitch of the tone received. However, we do not produce formal leak estimations.
Water finds the path of least resistance. Water can run through cracks in subsurface rock or make its way into storm, sanitary, and conduit piping. If the subsurface contains a high volume of sand, it will naturally flow farther down. There is no water visible on the surface in more than 99% of the leaks we locate.
GPRS's leak detection service is used to help municipalities and facilities maintain safe, efficient water distribution within a pressurized domestic supply network and fire protection systems. Often, water can leak from aging or broken infrastructure, creating unnecessary costs for clients. GPRS locates these water leaks, allowing our clients to reduce the number of costly excavations required for remediation.
