Southern Water say it is celebrating a record-breaking year for leak-busting.
It's all thanks to new technology installed on the streets and in the control room.
Water bosses say 25,000 acoustic sensors are now attached to the 15,500km of the region's water network.
Between April 2024 and April this year, they reduced weekly leakage by more than 15%, from 108.1 million litres per day to 91.1 million litres per day - saving 17 million litres every day, enough to serve 35000 customers.
Tim McMahon, Southern Waters Managing Director of Water, said: “There’s been incredibly work by our teams around the region – finding and fixing the leaks from big pipes far below the ground which show no trace on the street. Thanks to clever technology and new control systems, we are able to prevent pressure spikes which can burst water mains, and work as fast as possible to respond to every reported leak.
“We have our biggest ever water mains replacement programme underway with 50km of older PVC pipes being replaced by the latest technology during 2025 alone.
