More than two miles of old cast-iron pipes, which were laid more than a century ago, will be replaced with new hard-wearing modern pipes less prone to bursts and leaks.

The £2.5 million project started in July and will take seven months to complete. Most of the work will be done in Rushey Green and Bromley Road.

The project is part of a London-wide scheme to improve the capital’s pipes.

Head of Capital Delivery Lawrence Gosden said, “This is an essential project and one that will benefit people in Catford and the surrounding area for decades to come.”

“While we apologise for the inevitable disruption work of this nature causes, replacing old and leaking mains is essential as our water resources come under increasing pressure from climate change and population growth.

“Ideally we wouldn’t have to do this work at all, but the fact is London’s water pipes are old and leaky and need replacing. We are doing everything we can to keep disruption to a minimum.”

In the past five years, Thames Water has installed 1,300 miles of new pipe, cutting leakage by 27 per cent.

More than 20 per cent London’s water mains are over 150 years old – the oldest in the UK – and more than 40 per cent are over 100 years old.
