BORIS Johnson wants compulsory pay as you use’ mains water meters in every London home.

It is part of the Mayor’s new strategy to keep London watered with two million more people expected to live in the metropolis in the next 20 years.

His London Water Strategy is now out for public consultation looking at water supply and coping with floodwater drainage.

The strategy includes construction of a new Tideway tunnel under the Thames and River Lea in East London to reduce discharges of drain water and sewage into the river.

“It is easy to take our water in our taps for granted,” he said.

“Water is a vital resource which is under pressure from our expanding population and changing climate.

“We have enough water for London, but only if we use it wisely and effectively.”

Saving just a 10th of the 160 litres we use every day would fill 48 Olympic-sized swimming pools seven times a week, Boris points out.

He is working on proposals for the water companies to introduce compulsory water meters as one of the measures in his Water Strategy and wants more rainwater harvesting,’ grey water recycling’ and sustainable drainage.

Almost a-quarter of London homes already have water meters, City Hall points out, which are estimated to reduce consumption by to 10 per cent.
