> Water in the US is generally both widely available and inexpensive: my monthly water bill is roughly 5% of the cost of my monthly electricity bill, and the service is far more reliable.

In my experience with municipal utility districts, the reliability of the water supply is typically not much better than the local power grid. The sewage lift stations seem to have the highest quality generator arrangements.

bcrosby95•2h ago
Really? I've never turned my tap and and not had water come out. But we get several power outages per year.
password4321•1h ago
Water infrastructure outages are typically due to failures needing repairs (relevant to this discussion: water main breaks which lead to boil water advisories). Few municipalities are fiscally responsible enough to invest in all the preventative maintenance required to completely avoid failures across all types of infrastructure (a low-priority budget item when things are working smoothly), but it also takes decades for water mains to fail.
thanhhaimai•1h ago
It's interesting you said that. My experience is the opposite. In my last 10 years in California, I've had power outages a couple times a year (mostly due to storm / trees falling on the electrical lines). But I don't recall a time I got water cut off.
Aurornis•45m ago
> In my experience with municipal utility districts, the reliability of the water supply is typically not much better than the local power grid.

Both of these services have been phenomenally reliable everywhere I’ve lived in the United States. The only exception was in a town where we’d get ice storms once a year that would bring trees down on top of power lines, but it was shocking how quickly a truck would show up and fix them all.

I can’t actually think of a time my water has stopped working anywhere except once when the road was torn up and pipes had to be replaced. I wasn’t home, we just got letters explaining when it would happen and how to flush the pipes when it was done.

> The closest thing the federal government has to a department of water infrastructure, the Bureau of Reclamation, has an annual budget of just $1.1 billion.

One of my favorite books is Cadillac Desert. It's about the damming of the US rivers, the water crisis, and the history of the Bureau.

It may be dwarfed by the other departments, but its had a massive impact on US population development especially in LA.

> From 1902 to 1905, Eaton, Mulholland, and others engaged in underhanded methods to ensure that Los Angeles would gain the water rights in the Owens Valley, blocking the Bureau of Reclamation from building water infrastructure for the residents in Owens Valley.[12]: 48–69 [16]: 62–69 While Eaton engaged in most of the political maneuverings and chicanery,[16]: 62 Mulholland misled Los Angeles public opinion by dramatically understating the amount of water then available for Los Angeles' growth.[16]: 73 Mulholland also misled residents of the Owens Valley; he indicated that Los Angeles would only use unused flows in the Owens Valley, while planning on using the full water rights to fill the aquifer of the San Fernando Valley.

What a great article. Definitely bookmarking this for reference. People who oppose housing construction often invoke "but what about the water??" as their argument, while the fact is that California cities use less water per capita and overall than they did 50 years ago, almost entirely because of better toilets. The last couple of charts really highlight that trend.

Something else worth considering is that many uses at least in California are non-rivalrous. Reducing one water use does not necessarily create free supply of water for some other use, since water is a physical good that must be transported, refined, stored, and delivered. The best example of this is flood irrigation for rice in northern California. Bad optics, perhaps, but the fact is the rice is grown there because it was flooded in the first place. You can stop growing rice, and that will change one of the cells in your spreadsheet, but only because the spreadsheet model isn't quite right. You can also stop feeding cattle entirely and that isn't going to help cities with chronic supply problems, like Santa Barbara, nor will it benefit large urban systems like San Francisco and EBMUD who rely on dedicated alpine supplies.

newfocogi•1h ago
I found a lot of value in this article. Out of frustration with people who are alarmist over how much water a datacenter "consumes" compared to households, I've probably erred too often towards:

'People sometimes invoke the idea that water moves through a cycle and never really gets destroyed, in order to suggest that we don’t need to be concerned at all about water use. But while water may not get destroyed, it can get “used up” in the sense that it becomes infeasible or uneconomic to access it.'

Side note, this personal anecdote from the author caught me off guard: "my monthly water bill is roughly 5% of the cost of my monthly electricity bill". I'm in the American southwest (but not arid desert like parts of Arizona/Nevada/Utah), and my monthly water cost averages out annually to ~60% of the cost of electricity. Makes me wonder if my water prices are high, if my electricity prices are low, if my water usage is high or my electricity usage is low.

password4321•1h ago
I would like to know how much water is taken by a datacenter vs. the same size space of apartments. I can see why it could be considered a bad choice for communities long term if a datacenter takes more.
jeffbee•1h ago
Some quick napkin math using averages (data center designs vary). One of Google's larger and thirstier data centers, in Oklahoma, is said to use 833 million gallons per year (that's about 2500 acre-feet, in useful terms). It occupies about 250 acres, most of which looks to be parking lots but whatever. The number of households that can be supported on 1 acre-foot per year ranges from 2 to 6 depending (Las Vegas on one end, San Francisco on the other).

You said apartments specifically and this urban form usually starts at 50 dwellings per acre, minimum, which would lead me to say the apartments use more water. The break-even point in this equation is 2-5 households per acre.

NegativeLatency•1h ago
Apples and oranges, you can compare the water usage, but places for people to live aren't in the same category as datacenters.

The government in The Dalles, Oregon were suing local newspapers that were questioning Google's water usage in the city:

https://www.rcfp.org/dalles-google-oregonian-settlement/

Apparently Google uses nearly 30% of the city's water supply:

https://www.oregonlive.com/silicon-forest/2022/12/googles-wa...

I highly doubt any apartment block comes close to taking 30% of a city's water supply.

Aurornis•56m ago
I’ve driven through The Dalles. It’s a very small town. A search shows a population of 15,000 and declining annually.

It’s also right on a big river. The article you linked said that Google was spending nearly $30 million to improve the city’s water infrastructure so there are no problems.

Talking about this in terms of percentages of a small town’s water supply while ignoring the fact that the city is literally on a giant river and Google is paying for the water infrastructure is misleading.

jeffbee•55m ago
That's because it's a large industry and nobody lives there. This pattern appears all over the place. The paper mills in the pacific northwest consume large multiples of the water used by their little towns.

Biggest alarmist is movement against Nestle using water for bottled water in California. They don’t even use as much as an average golf course.

How much water is wasted on golf courses in these arid regions? Or growing water intensive crops like alfalfa that isn’t even directly used to feed people.

sellmesoap•1h ago
There are a lot of historical reasons for people to be angry at Nestle, aside from their impact on water.
recallingmemory•57m ago
Yep, 1.6 trillion gallons of water from the Colorado river goes into irrigation for alfalfa[1]. Google's total water consumption across all data centers in 2023 was 6.4 billion gallons[2].

People are sounding the alarm about water usage in AI data centers while ignoring the real unsustainable industries like animal agriculture.

tzs•29m ago
You are overlooking location. The ideal place to grow crops is a place with great soil, good weather, a long growing season, and abundant water, but there aren't a lot of those. Of those four things, water is the only one that can be reasonably transported.

Data centers have fewer constraints. It should be possible to place more or all of them in places where water is abundant.

recallingmemory•16m ago
My comment was just focused on total water use. I agree that location does matter, and that data centers should be placed where water is abundant.

It still doesn't change my concern about how unsustainable growing alfalfa is. Trillions of gallons to grow an inefficient animal feed crop while we're told by the evening news to take shorter showers (8 minute shower is ~16 gallons of water) and let our lawns die.

FredPret•6m ago
> How much water is wasted on golf courses...

Zero. You can't waste water, it goes in a cycle.

I mean unless you transport it off-planet.

You can waste the energy you spent cleaning it and pumping it around. But between nuclear and solar we ought to have an overabundance of that.

In a market economy, if it becomes "economically infeasible" to purify used water, the price goes up slightly, and suddenly it makes a lot more sense to treat dirty water, or even seawater.

You see the same type of argument against oil or mineral use; the idea that we'll run out. But people who argue we'll run out almost always look at confirmed reserves that are economical to extract right now. When prices rise, this sends a signal to prospectors and miners to go look for more, and it also makes far more reserves economical.

For example, Alberta's oil sands were never counted as oil reserves in bygone decades, because mining it made no sense at the time. But the economy grew per capita and overall, prices rose, and suddenly Canada is an oil-rich nation.

A similar dynamic applies to water and everything else.

Of course there are finite amounts of oil and uranium and so on, but the amounts just on this one planet are absolutely mind-boggling. The Earth has a radius of 6400km, and our deepest mines are 3-4km. We may expect richer mineral deposits (not oil) as we go further down.

Keep following this price logic and at a certain point it'll make sense to mine the far side of the moon, the asteroid belt, and so on ad infinitum.

You can waste water because not all water sources are equally renewable. Some underground aquifers recharge slower than we extract from them.

Fresh water in a reservoir above a water treatment plant is not the same as salt water in the ocean even if it's the same molecule in the same cycle.

With no AC and gas hot water, my monthly water bill is ~150% of my electric (that water cost is not including the wastewater that is billed on the water metering).

My water usage is pretty average and my electric usage is apparently hilariously low.

hammock•32m ago
>I'm in the American southwest (but not arid desert like parts of Arizona/Nevada/Utah)

Doesn’t matter whether you are in the desert or not, only matters if you are in a shared watershed with them. There is huge agricultural demand for water and water rights in those areas which translates to high prices for the areas where they can source water (like your presumably more-watered location)

I live in the northwest US. My water bill is 110%-120% of my electric bill.
rawgabbit•1h ago
It said 41% of the water used in the US is for thermo electric cooling. Albeit, it didn't break this down into saltwater vs freshwater. It also said the vast majority of this water usage is due to older plants that did not recirculate the water. The newer plants that recirculate the water only used a tiny fraction of water in comparison.

So...if the US replaces all of its old nuclear power plants, we would free up almost 40% of water used today?

How did you go from "thermoelectric" to "nuclear"? The US has nearly as much coal power as nuclear power, and significantly more natural gas than nuclear.

widforss•1h ago
I recently looked up whether it would be worth it to me to install a water meter instead of paying a flat-rate. Apparently the flat rate is calculated on a consumption of avout half a cubic meter per day. But, without a water meter, I can only guess if my consumption is more or less than that. My guess is that it's considerably less though.

Maybe there are regs on appliances in Europe, or maybe the prices are high enough that the market demands efficient appliances (like gas/petrol). Whenever I stay in an airbnb in europe, whether it is a fancy place or a cheap apartment, all the appliances look similarly small and water efficient. The washing machine, flushing, hot water heaters, etc. can all add up. To wit, there is no uniform water efficiency requirements in the US.
mjmahone17•1h ago
It’s probably the lawns and yards, primarily. Including things like pools: in Arizona there’s about one pool for every 13 people. The US averages much larger lot sizes, and those yards consume water.

I’m not saying the US isn’t profligate in other areas like appliances or taking longer showers, but in most the country there’s so much land, such cheap water and very little regulation preventing you from using however much water that you want. Some of the land even comes with a guaranteed quantity of water for irrigation guaranteed, at little to no cost.

hammock•1h ago
What they are calling “per capita domestic water use” is the per capita public+self supplied, which is not the same as home use. They sort of hand-wave over “most of this is used at home” but really it is inclusive of not only lawns (which are bigger in the US) but commercial use of water as well- commercial landscaping (far more in the US than in Europe) and other business use

Plumbing fixtures are also more regulated in the EU but I suspect this is a small portion relative to landscaping.

gonzalohm•55m ago
One thing that shocks me as an immigrant from Europe to the US is toilets. I have not seen a single one that has the two buttons, one for pee and one for the other stuff.

Every time I use the toilet it uses 1.6 gallons. 6 liters...

I think in my home country more than 90% of home toilets are the "low water usage one" (with 3 and 6 liters buttons)

And that's only the start, I noticed that people just don't care about water usage over here. People take water from wells with little oversight. In my home country you need a vast amount of bureaucracy to be allowed to take water from aquifers

aerostable_slug•20m ago
The two button toilets are around, but I agree that they aren't the standard.

Also, wells are regulated in the US, with the exception of low-producing home wells. Even then, they require permitting (the degree of difficulty depends largely upon the state in question). Larger-producing wells have all kinds of reporting and usage requirements associated with them, and water rights can be the most valuable part of a plot of land.

Water and the control of it is the story of the modern American West. Even today, there are a couple of folks up in a coastal community in my county who are fighting to be able to build single family homes on property they bought decades ago. The issue is, you guessed it, water.

RandallBrown•10m ago
Interesting. I feel like the majority of toilets (in my US city) have both buttons and it's been that way for almost a decade.

The only time they don't is when it's a toilet that's over 10 years old.

I could be wrong, especially since I mostly just use my own toilet (has two buttons, is 6 years old) or a urinal.

carlhjerpe•6m ago
EU put forwards some Eco labeling thing in 2013 to encourage toilet manufacturers to get eco certified and people buy the stuff (though it was already common long before 2013)

Regulation can be for the greater good, and in this case it's not even mandatory.

I feel like there's a cultural difference where wastefulness is frowned upon at home but encouraged in the US. Big cars, big trucks(cars), big trucks(lorries), big (green)lawns, big roads, big houses, big servings, drive everywhere, fly everywhere, no trains, no public transport.

Everything is big except infrastructure unrelated to cars. Except for some cool dams built before something shifted.

And as others mentioned, the "water rights" which can be traded(bought up) by some evil megacorp instead of benefiting local farmers and population becaue ownership trumps everything.

scythe•52m ago
Potter's analysis of the various consumptive uses of water relies on the USGS survey data of the uses of water, generally a good source. However, there is a small flaw when we try to turn consumptive use into consumption, which is alluded to but not quantified in the USGS report: water losses to evaporation during storage (in reservoirs) and transportation. This is discussed in e.g.:

https://journals.ametsoc.org/view/journals/bams/99/1/bams-d-...

https://www.sciencedirect.com/science/article/abs/pii/S00344... (translation: 33.73e9 m^3/yr ≈ 24400 Mgal/day, roughly corn + alfalfa + steel)

Much of the literature is preliminary and recommends further study, but the initial estimates indicate that the amount of water that is simply lost from reservoirs is surprisingly large. So I like to yak about covering reservoirs (possibly with solar panels), which won't solve everything, but it has a far larger impact than data centers.

Aside: metric, please!
