Leaks like to hide deep underground, which makes them difficult to find in our 20,000-mile pipe network. We attach our cutting-edge sound detectors to at-risk pipes so we can listen for the sound of water leaking out of them. This helps our leak teams find and fix around 1,100 leaks a week. Our aim is to reduce leaks by 20% by 2025. Find out more at thameswater.co.uk/leakage | Thames Water
