It… doesn’t look that bad. Electricity use is sizable. Water which usually gets all this screaming is, well, look up how much a golf course or a large hotel uses.
mitxela•37m ago
Concern about water use is the distraction they caused in the media so we'd too busy thinking about fake issues to think about the real issues.
YetAnotherNick•29m ago
Not a conspiracy theorist, but wait that really sounds effective. Just few months back I was wondering why were big datacenter companies not trying to sway the public that the water usage is low per query or whatever metric.

There will be protests and cases related to water usage of AI, but none of them would hold any ground. And winning the water case would just make the argument in their favour.

dylan604•23m ago
Which begs the question of who was the source of the water/electricity FUD?
DANmode•17m ago
You don’t have to create unrest, sometimes you just have to let it go unchecked in the right spots.

Just a few months more, and the public was still often making Epstein references.

So, basically, not a meaningful amount of water at all. Credit to the story authors for taking the time to frame what 13MM gallons actually works out to.
demibabs•30m ago
“Fireball Group LLC, the Google Data Center in Papillion… reports 547.88 megagallons for their 2025 Annual Water Consumption”.

I think the 13M is referring to “during peak times”, whatever that means.

XMPPwocky•26m ago
It looks to me like there's two Google DCs with different LLCs?

> However, using a computer cursor to highlight the redacted text box in the report to DWEE, then copying and pasting it into a separate document reveals that *Agate LLC* is reporting 52.65 megawatts of electricity during peak electrical demand and 13.299 megagallons of water between cooling towers, evaporative systems and site operations in the last year. That totals out to 13 million gallons of water.

> For context, 13 million gallons is enough to fill around 20 Olympic-size swimming pools, and is less than half of what the City of Lincoln reports using on Sept. 29.

> The *six* data centers reporting as of Sept. 30 show a total use of 765 million gallons of water last year, enough water to fill 1,159.93 Olympic-size swimming pools.

> More improper redaction shows that the data center using the most water annually is *Fireball Group LLC*, the Google Data Center in Papillion. Fireball LLC reports 547.88 megagallons for their 2025 Annual Water Consumption.

tptacek•21m ago
Even that 765 is like 0.04% of the water needed to irrigate Nebraska's ethanol corn crop alone. And ethanol is basically an agricultural proof-of-work function.
pavel_lishin•36m ago
> For context, 13 million gallons is enough to fill around 20 Olympic-size swimming pools, and is less than half of what the City of Lincoln reports using on Sept. 29.

Over the course of a year, that doesn't sound terrible.

persedes•31m ago
That's wishful thinking, I know, but would love a breakdown of those metrics into what actually goes into AI inference, training versus just TikTok / YouTube streaming, or just a Google search...To have some perspective. My hypothesis that prolonged video streaming might contribute similarly to AI usage? (But CDN etc might make that tricky to calculate...)
tptacek•26m ago
It's not terrible at all. It's dwarfed by common municipal demands, let alone industry or agriculture. It's an amount of water that's basically not worth talking about.
1-6•32m ago
You can get better cooling performance at the cost of slight water usage or you can use more energy without using water at all.

The greener solution is to use water.

XMPPwocky•25m ago
Seems like it'd depend a lot on e.g. carbon impact of the marginal watt v.s. environmental impact of the marginal gallon? Might depend on the individual site.

I lived in a smaller rural town near a Google datacenter. During my career there I had routinely come across some outlandish accusations made about our water/power usage from the locals. But for obvious reasons I could never dispute them. I remember we hired a local who'd grown up in the town and he was "really surprised" when he started to see what we were doing to remain efficient.

The current data center craze just feels like the same thing but on a bigger scale.

cyanydeez•25m ago
it's interesting how much this sounds like astroturf.
hypfer•12m ago
LinkedIn CV says 8 Years working for google as a Data Center Facilities Technician, so. Yeah.

Not necessarily astroturfed but definitely biased.

bix6•13m ago
Ok and? This wouldn’t be an issue if google et al would just share the numbers instead of hiding behind NDAs and whatever else.
dylan604•25m ago
This document was created after the Epstein redaction debacle and yet they still leaked redacted data. People will never learn. <facepalm>
motionlessveloc•21m ago
I don't really understand the hand-wringing about data centers and water. Unlike fossil fuels, when you "use" water, it doesn't go away, it goes back out into the environment. And since DCs use it for cooling, not some industrial process, it doesn't even contaminate the water in any meaningful way.

The one exception is if they're using fossil water pumped from aquifers, which doesn't renew (back into the aquifer that is), but nobody seems to bother to make the distinction.

debatem1•12m ago
I would love to see a real breakdown of aquifer water usage.
blensor•11m ago
I think the bigger issue with water usage ( if it's actually an issue ) is when the system is not able to handle the additional demand ( drying up wells, etc. ) Especially during the summer where water supply is already strained in some areas.

Yes water goes eventually back into circulation but that does not help in the place where the system is already at it's limit

bix6•9m ago
IMO the water thing is a distraction. It gets people quibbling over water instead of asking bigger questions about the data center.

There is sometimes incorrect conflation between what the datacenter is permitted for and what the datacenter actually draws.

> Many articles about current or future AI data centers report the number in the water permit they apply for as the amount of water they actually use day to day. But this almost never happens. [1]

This is from the problematic and often wrong but in this case correct Andy Masley. It's not completely clear to me whether this number is observed usage or a theoretical permitted maximum, in which case the actual usage could be even lower. It could be either.

[1] https://blog.andymasley.com/p/the-ai-water-issue-is-fake?ope...

bix6•11m ago
Ok but if you are permitted for some obscene number you could at any point draw that down no?
drnick1•19m ago
So what? Water used for cooling doesn't disappear.
grebc•12m ago
You can’t eat your algorithm.

So while pointing to agriculture and saying look there - those guys & gals way more than us it’s a red herring because we need food.

Sure improve efficiency of ag, but a better comp for water usage should be made. Reasonable people tune out.

arccy•4m ago
you can't eat ethanol either, you burn it to create more global warming
logicprog•3m ago
That's why they talked about ethanol.
deckar01•24m ago
Are you regularly filling Olympic sized pools and checking the water usage of an entire town in Nebraska? I would rather see this put into context by comparing it to other businesses normalized by power usage or square footage.
tptacek•20m ago
No, I'm not checking the water usage of Olympic swimming pools, because I intuitively understand that they are not meaningful users of water.
dekhn•5m ago
Different state, but: almond trees growing in California consume 1 trillion gallons a year (estimated).

So probably we could grow fewer almonds in California.

maccard•17m ago
I live in a country of 5 million people and we lose 40 times that a year to leaks.
mrb•14m ago
Yes. As another comparison point, 13 million gallons per year amounts to 24 gallons per minute which is about 5 (five) bathtub faucets running 24/7/365.

The water bill alone would be only $100k/yr assuming average US domestic rate of $8 per 1000 gallons.

gspr•5m ago
What I now wonder is why the hell they're trying to hide it then. If the numbers are strongly on your side, why hide them?!
motbus3•4m ago
Please elucidate if I'm wrong, but, isn't the problem the distribution of the water and not the amount? If you install a building of people in a road that is not prepared for that, all people down the people are in risk of lack of water.

I think at some point someone used the argument of the spoon of water to say about the quantity, but I remember to see explanations that it was unrelated.

fastball•7m ago
Are you sure? People think water for data centers is "consumed", like the output is sewage or something. Giving those people concrete numbers is not gonna change such misconceptions (and that's assuming they look at such numbers in reasonable relative terms in the first place).
anigbrowl•4m ago

PunchyHamster•12m ago
It is worth remembering that it heavily depends on cooling system involved.

Traditional data centers have far smaller power density per rack and thus cooling requirements than AI datacenters; if you can use closed loop system without evaporation, water usage is very small. Difference is around order of magnitude

But if you want to fit maximum amount of compute in the space and need to dissipate it, evaporative based system will be far more effective space wise; especially if also for some reason you built it in hot place, rather than somewhere in the north

michaelt•4m ago

It'd be pretty easy for the company to dispel those outlandish accusations - the PR department could just report the true numbers.

Your use of "into the environment" is too broad.

If you pump water out of one watershed into another then you better expect the downstream users, deprived of their water, to complain.

For example, the upstream users of water from the Colorado use so much that Colorado River Delta is nearly always dry. Or read about the California water wars.

Further, increased competition for surface water raises prices, which encourages additional aquifer extraction.
