How we find and fix leaks | Leakage | My Supply | Severn Trent Water

Acoustic loggers are a major part of our leak detection technology. They pick up vibrations from a leak when they’re attached to a pipe. Those vibrations are reviewed by our technicians who can use that information to find a leak.We often use these at night, when the network is at its quietest and there is less background noise. The loggers listen out for the distinctive sound patterns that escaping water produces.We also have pressure loggers, permanently assessing the pressure levels in our pipes. These are able to detect changes in flow and pressure. If there is an unexpected drop in pressure, that suggests there may be a leak. By placing one of these loggers at either end of a section of pipe that we are investigating, we can use the data they collect to triangulate the position of the leak. We're then able to tell if the issue is on our network or on private pipework. If it's on our network, the data helps us to make sure we dig in the right place so we can get to work fixing it q...
