We have so far replaced more than 400 miles of old and leaky water mains in
London – enough to stretch from London to Aberdeen. The work is essential to
reduce leakage and ensure that the capital's growing population continues to
receive the water it needs. Drier summers linked to climate change increase
the urgency of this work.
We are accelerating this work, and by 2010 will have renewed over 1,100 miles
of water mains in London. About 1,400 staff are currently working in over 30
locations, removing cast iron pipes which in many cases date from Victorian
times and replacing them with more durable and flexible plastic pipes.
Although the work inevitably involves some short-term disruption, it will
bring many long-term benefits, most importantly a reduction in the potential
for future bursts and leaks, minimising the need for more streetworks.
We are doing all we can to minimise disruption – for example, we aim to
complete as much work as possible using ‘no dig’ technology, which removes the
need to dig long trenches along streets.
