Only two UK water companies managed to reduce leakage last year - Yorkshire Water and Severn Trent.
Figures – based on the amount of leakage as a percentage of the water supplied – a show that leakage in Yorkshire reduced by 0.41% during 2012-13 when compared to 2011-12.
Tony O’Shea, Yorkshire Water’s leakage manager said: “We’re obviously pleased with this performance which showed that we reduced leakage by a further 7Mld last year and out turned 30Mld below target, but we’re not resting on our laurels.
“Water which is lost from the system is effectively water we have paid to treat and move around the supply system without anyone getting any benefit from it, and we want to ensure that this happens as little as possible.”
The water company maintains 19,500 miles of clean water pipes – enough to go to Australia and back if laid end to end.
