Act now on water or face emergency queues on the streets, UK warned

Govt warned 4 years ago.
UK has Europe's highest consumption.
3 million Tonnes of water lost by leakage daily!
The energy implications of the transfer arrangements interest me. Canal locks have been considered for small-scale hydro (on the by-wash) but if they want to use the main canal for water transfer there will be lots of pumping stations pushing water up half of the lock flights... could be an integrated solar pv and pump module (to be delivered by boat, of course) at each lock. Still (or even more) HEP to be generated from the water falling down the London- bound locks though.
More likely they will just bury a big main under the tow-path of ascending lock flights and consume tons of power pushing the water uphill with a big pump at the bottom.
Well, who would have thought it?Hosepipe ban and compulsory water metering needed, say advisers, as nation braces for drought
The government was warned four years ago by the National Infrastructure Committee (NIC) that considerable new investment would have to be made in the nation’s water supply equipment by the 2030s. Although some improvements have been made by water firms, nearly 3billion litres of water is still lost every day.
“You have to pay for it, one way or another,” he said. “That could be investing in new reservoirs or moving water around the country, as well as stopping leaks.” Water metering is considered by the industry as the best tool for cutting water use – the UK has the highest usage in Europe. It is estimated that water meters have been installed in only about half of households in England and Wales, but these customers use 33 litres a day less than the national average, of 141 litres a day.
A conglomerate of government bodies said that major plans were being prepared to improve water storage and transfer across England and Wales. A £500million scheme called Rapid – Regulators’ Alliance for Progressing Infrastructure Development – was set up jointly in 2019 by Ofwat, the Environment Agency (EA) and the Drinking Water Inspectorate.
“We are now investigating different schemes with the aim of implementing the most promising in a couple of years,” said Paul Hickey, managing director of Rapid.
Among the projects being considered are a series of new reservoirs that could be built in different parts of the country and schemes that would allow engineers to transfer water from the north of England, where supplies are not stressed, to the south. These would involve using the River Severn and the Grand Union canal as conduits for fresh water that would alleviate situation in the south of England, which has been worst affected by the drought.
