Engineers fix Battersea leak
Thames Water engineers exploring secret tunnels under Battersea Power Station have repaired a pipe that was leaking enough water to supply more than 1,000 customers every day.
Thames Water has ramped up its investigative ‘find and fix’ work to reduce leakage from underground pipes using a full range of methods, including satellites, sound alarms, listening sticks, sniffer dogs and by walking the company’s 180 kilometres of service tunnels.
The Battersea team discovered a single point on the one metre-wide trunk main under the iconic power station was losing around 150,000 litres a day – enough to fill an Olympic-sized swimming pool every 17 days.
They also plugged a number of smaller leaks by tightening joints and carried out further maintenance work in confined space to reduce the risk of bursts and disruption to south west London customer supplies in the future.
Mike Kodua from Thames Water said: “We’re actively controlling more aspects of how we manage the network and these tunnel inspections are proving a valuable way of discovering and plugging leaks. The team in Battersea has done an amazing job in challenging conditions and we hope covering extra miles underground will help save more water across our vast region in the future.
“Keeping taps flowing in the face of population growth and climate change while reducing leakage remains a top priority for the business. We’re spending more than £1 million every day on the challenge and expect our leakage performance to continuously improve this year, in line with our target of a 15 per cent reduction by 2025.”
