everal water firms got here near breaching their licences as a way to keep public water provide after the extreme warmth and dry climate final summer time, Environment Agency (EA) paperwork present.
Obtained via a freedom of data request by Unearthed, Greenpeace’s investigative journalism unit, the paperwork present how the EA was nervous about firms not having sufficient clear water with which to provide their clients.
The majority of reservoirs had been “exceptionally low” by September, with some close to to the purpose of being classed as “dead storage”, the place the standard of the remaining water is so poor that treating it is probably not doable.
Yorkshire Water helicoptered a short lived pipeline throughout a protected space so it might switch water from one reservoir to a different whereas Southern Water got here near reaching the authorized restrict it might summary from a chalk stream.
Reservoirs within the South West had been additionally critically low. One particularly, the Upper Tamar, would have emptied and “become unusable” with no drought allow, the EA mentioned.
With leaky infrastructure losing as much as a trillion litres of water a yr and no new reservoirs constructed for many years, local weather change might deliver extreme water shortages to the UK and as soon as once more this Government is enjoying quick and unfastened with the way forward for the nation
The area stays in drought standing one yr on with a hosepipe ban nonetheless in place throughout Cornwall and now components of Devon, although that is set to carry on the finish of September, South West Water mentioned.
Campaigners imagine the disaster to be a making of the water business’s neglect of infrastructure with the Government failing to carry it to account.
Megan Corton Scott, political campaigner for Greenpeace UK, mentioned: “With leaky infrastructure wasting up to a trillion litres of water a year and no new reservoirs built for decades, climate change could bring severe water shortages to the UK and once again this Government is playing fast and loose with the future of the country.”
The EA paperwork present how the company was involved that Yorkshire Water might doubtlessly injury a protected pure space on the South Pennine Moors by transferring water from the Walshaw Dean Upper reservoir to Ponden reservoir in Worth Valley.
Levels in Worth Valley had dropped to under 28% of their capability by final September and had been forecast to fall by an additional 20%.
Yorkshire Water mentioned its actions ensured their was no interruption to folks’s water provide and that it spoke with Natural England about not disturbing the South Pennine Moors throughout the water switch.
A spokesperson mentioned: “As a responsible landowner in the area, we completely understand the sensitivity of the South Pennine Moors and operate within these protected sites regularly so we used helicopters to help us transport and lay a temporary pipeline across the South Pennine Moors from Walshaw Dean reservoir to Ponden reservoir.”
Southern Water mentioned it got here near breaching the authorized restrict of what it might summary from the Tess and Itchen rivers in Hampshire as a result of its allowance was tightened in 2019, which means it needed to apply for a drought allow late final summer time.
This would have posed a threat to Atlantic salmon that use the river, based on the EA paperwork, although Southern Water mentioned the allow was not wanted ultimately following autumn rain and so it was withdrawn.
In the occasion, ranges on the river by no means dropped under the hands-off circulation, no drought allow was wanted and we withdrew our software
A spokesperson mentioned: “In 2022 as we saw river levels drop, we applied for a drought permit and did everything we could to reduce demand and protect the rivers including widespread water efficiency advertising and eventually the imposition of a temporary-use ban.
“In the event, levels on the river never dropped below the hands-off flow, no drought permit was needed and we withdrew our application.”
The EA warned South West Water that they must begin offering bottled water and tanker vehicles if the dry climate continued, the paperwork present.
They issued a drought allow to assist South West Water refill the Colliford reservoir over the winter, which the company described as a “strategic” reservoir for Cornwall and mentioned there are “significant risks to security of supply next year” if the corporate doesn't use the drought allow.
A spokesperson for South West Water advised Unearthed there had solely been stress at Colliford and that nobody suffered lack of provide, whereas they strongly disagree with any suggestion of the corporate being unprepared.
An EA spokesperson mentioned: “Last year’s summer was one of the hottest on record. The Environment Agency worked to provide timely advice to government, ensure water companies were implementing their drought plans and helping farmers to manage resources.
“Through the National Drought Group, we will always review what can be done to improve our future preparedness and strengthen our planning.”
