We've been testing the use of drones with thermal cameras to detect leaks, helping us access areas that aren't safe or easy for our technicians to navigate at night. You can see the leak below in yellow: | Thames Water

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
