Water UK warns there’s not enough water for datacentre plans

techJul 21, 2026281,823

Water UK told MPs that government water forecasts are "fatally flawed" because they "explicitly exclude" datacentre demand, warning the UK will not have enough water for planned datacentre expansion. The trade body said the government’s AI growth zone policy, AI for science strategy and AI opportunities action plan make no mention of water, and the Environment Agency’s June 2025 national water resources framework also omits datacentre water estimates. Water UK estimated datacentres in England already use 6.6 million litres of drinking water a day and said tripling datacentre capacity by 2030 could raise that to 19.8 million litres a day. A House of Lords report in May found England faces a 5 billion litre a day shortfall for public water supplies by 2055; Water UK noted more than three quarters of datacentres are concentrated in the south and east, regions repeatedly placed under hosepipe bans. Affinity Water told MPs about roughly 125 datacentres proposed or under construction in its region and that some facilities have requested up to 3 million litres a day, equivalent to peak demand for about 3,500 homes. Water UK said new growth in water-stressed areas "may be impossible" without policy change, because leakage and demand targets are already ambitious and new large supplies or reservoirs can take about 15 years to plan and build; Jon Chappel, Water UK’s deputy director, called the omission "unforgivable" and a "genuine failing of government."

The UK will not have enough water for future datacentres. England faces 5bn litre a day shortfall for public water supplies. A trillion litres of water a year lost to leaks. Widespread hosepipe bans. No national grid for water. Poor infrastructure. No national plan.

I have a solution. *Don't build the sodding datacentres.* Have all the people in power lost the plot?

Literally every single person on here who takes an anti-anti-datacentre perspective on this has kind of failed to explain to me what is so bad about the prospect of us just not building any more of them.

But the AI bros keep telling me that water usage is not a problem. The officials must be lying.

Fortunately, between OpenAI’s advertising shortfall and the first SpaceX lockup period coming to an end on 6th August, along with various banks bundling their exposure, and various of the “Magnificent Seven” selling off parts of their stakes in Data Centres, those data certainly may be cancelled

How the fuck are we supposed to make our Vimto with no fucking water??

I’ll rewrite the headline for them: not enough water for people if Data Centres built

Vattnet - människovärdet ställs mot massivt oproportionerlig invasion av datacentraler (även hos oss). Ett sådant förödande slöseri med droppar, som utmanar grundläggande behov för livsvärdet under pågående klimatkris… orsakad av människans tanklöst giriga oproportionerliga utsläpp av växthusgaser.

We are losing out on water for our gardens because of data centres.

Water. Why on EARTH some Scots don't want Scottish Independence, is beyond me. It's almost like they ENJOY being skint and troubled. There's more water in just Loch Ness, than every Lake in England, put together. All of them.

Yet I’m sure that app’s for these AI/DC’s will be approv. by muni/regional districts b/c they tell their constituents they bring tax revs/jobs. Nothing could be further than the truth. They’re digital locusts who’ll consume everything, with no regard for life. #TheMachinesRise #TechBillionaires
