United Utilities says its rolling a huge “listening” project in a bid to tackle water leakage.The North West water company is installing around 100,000 ‘acoustic’ loggers over the next two years on its underground water supply network.
How Does It Work?
1. An acoustic logger is a small device that would fit in the palm of a hand, installed directly onto the fittings of a water pipe. 2. The loggers “listen” for the characteristic noise waves that are transferred through pipe walls by a leak, and upon detection of the sound they send an alarm to United Utilities’ integrated control centre. 3. Analysts can then send an engineer to pinpoint the leak and get it repaired.
