AIBU to question hosepipe bans while AI water use gets little scrutiny

AIBU to think it’s ridiculous that there is a hosepipe ban and I cannot water my plants in this heat whilst I see hardly any discussions or questions raised about the massive drain on our water resources by AI?

Bringing in a hosepipe ban after two days is a ridiculous overreaction. We had loads of rain over the past few weeks and on Monday night in fact and there is more forecast for next week.

Rather than just AI we need to be questioning why it is that the water companies are losing billions of gallons due to substandard infrastructure while charging the earth for their supply and their executives receiving fat bonuses.

It’s time people stuck two fingers up at these hosepipe bans which aren’t enforceable anyway. But it’s far easier for individuals to turn on each other rather than to question what’s really going on.

As for AI, I hope in five years time the majority of it has imploded. People seem to have no idea the damage which is being done by AI.

It’s estimated that a 3rd of jobs will be taken by AI. We’re raising a generation who will soon be illiterate non communicators because they just get AI to write their emails, their texts, they won’t need CV’s or cover letters because they won’t have jobs to go to.

The music industry will have died because currently the top artists on Spotify are AI generated from Suno and its ilk.

Great if you want to use it as a search engine, but a therapist? Something to write your emails? An imaginary friend? The sooner it dies the better.

Are you vegan? Because if you are not, and you are worried about water usage… well, your worries are very much misplaced. https://www.openaccessgovernment.org/devastating-water-footprint-animal-agriculture/163485/ (and yes, I am vegan for ethical and environmental reasons)

Yes or vegetarian working towards becoming vegan like you. I can worry about more than one thing😊

You're probably right, but Kent has had hosepipe bans from before AI even existed.

I don’t think it’s debatable that AI is contributing to climate change. I think that is a pretty established fact.

I mean, technically it is true, me lighting a single match would contribute to climate change a tiny bit. But the global impact of AI and data centers is still miniscule compared to global manufacturing, transport, concrete production, beef farming etc.

I initially clicked the agree emoji, but retracted it. I don’t think we can say that AI data centres are definitely contributing to climate change, but we need to monitor the situation. These centres are power and resource hungry. Can we sustain them? Probably not.

Is there a way we could discuss that without needing to read 25 pages?

Get ChatGPT to summarize it? 😉

AI uses less than a teaspoon of water per search

I’ve read it, so you don’t have to…

Global and UK water consumption statistics for AI and data centres
The scale of water consumption by AI and data centres is significant and rapidly
increasing, posing a global challenge with direct implications for the UK.
Globally, the International Energy Agency (IEA) estimates that the data centre sector
consumes over 560 billion litres of water annually. Projections indicate this figure could
rise dramatically, reaching as high as 1,200 billion litres by 2030.13

And I think that golf courses around the world use something like 3 trillion litres of water per year, and leaky pipes in the uk waste over 1 trillion litres per year.

AI will hopefully do a huge amount of good in the medical and scientific fields, can’t say the same about golf or leaky pipes.

Insufferable mare to worry about the environment ? You are completely missing missing my point. This isn’t about my peonies. Climate change will also affect your son, so maybe start educating yourself about it a bit? 😊

Surely all of the data centres are in the USA? They don’t have any impact on water in Kent. It’s not like water is a resource that can be moved around from the Us to Kent!

They're all over the world including some in the UK.

Apparently streaming now uses up more energy than making tea and coffee.

Sorry, the full stop and bracket got added to my original link, this should work:
https://mosl.co.uk/news-and-events/news/data-centre-study-calls-for-new-reporting-framework-to-manage-water-use

Also my maths might have been wrong by a factor of 1000, but the point still stands.

An interesting report. Good ol’ WRC.
What struck me was this paragraph. Interesting that these large consumption data centres have come online recently. AI?
‘This consumption is highly skewed towards the large water users, with the top six data centres accounting for 65% of the sector’s water consumption. Many of these appear to have come online in the last few years’

What about avocado water? Or is that different?

MMBaranova · 25/06/2026 19:13

I asked ChatClawdRok who said ‘why are you asking me? If there’s a hosepipe ban, you don’t use me in solidarity.’

That link doesn’t work, but I would be interested in reading it. The report I linked to was talking about the increase in UK data centres. These centres are classed as critical to our national infrastructure, so they will be increasing.
Our water resources are at breaking point already, so we need to work out how we are going to supply both domestic and retail water.

If only that were true but courtesy of mr google there are currently between 475 and 564 active data centres in the UK. Most major industry trackers and media outlets estimate the total count to be around 500 operational facilities nationwide.

Good question OP.

Of which the vast majority are traditional (non-AI) datacentres that use air cooling rather than water cooling. Air cooling is perfectly sufficient for traditional servers without GPUs.

The handful of water-cooled AI datacentres we do have in the UK use closed-loop cooling so very little water is wasted (a little from evaporation). Open loop just doesn’t make sense economically in the UK.

Everyone is linking to stats about global water usage by AI. Most of them are in the USA and China. The current UK water supply is ~14,000 billion litres/day (bottom of page 7 of the paper @MezeAndNibbles linked to). In the UK, data centers use 1.87 million litres per year (https://mosl.co.uk/news-and-events/news/data-centre-study-calls-for-new-reporting-framework-to-manage-water-use).

So in the UK, data centers currently use about 0.0000000000366% of our available water. We really dont have many data centers.

I would argue we need to look at shit being pumped into our rivers, massive profits being made before we worry about usage

An we not worry about both?

I am in Kent and yes I won’t let my plants die. It my question was more about why we don’t care about AI water usage which is a lot more damaging for the environment as a whole.

Everyone bangs on about data centre water use literally every time AI is mentioned, as though data centres never existed before AI and half the infrastructure of our lives isn't reliant on computer stuff that needs data storage.

YABU to object to AI water use but also ignore a hosepipe ban to water your own garden, because it's inconsistent. But the water being used to cool AI centres is probably not the same reason your local water company is asking people to be sparing with their water use. These are two separate issues.
