Google Data Centers' Secret Cost: Billions of Gallons of Water (bloomberg.com) 156

To meet surging demand for online information, internet giant taps public water supplies that are already straining from overuse. From a report: In August 2019, the Arizona Municipal Water Users Association built a 16-foot pyramid of jugs in its main entrance in Phoenix. The goal was to show residents of this desert region how much water they each use a day -- 120 gallons -- and to encourage conservation. "We must continue to do our part every day," executive director Warren Tenney wrote in a blog post. "Some of us are still high-end water users who could look for more ways to use water a bit more wisely." A few weeks earlier in nearby Mesa, Google was finalizing plans for a giant data center among the cacti and tumbleweeds. The town is a founding member of the Arizona Municipal Water Users Association, but water conservation took a back seat in the deal it struck with the largest U.S. internet company. Google is guaranteed 1 million gallons a day to cool the data center, and up to 4 million gallons a day if it hits project milestones. If that was a pyramid of water jugs, it would tower thousands of feet into Arizona's cloudless sky.

Alphabet's Google is building more data centers across the U.S. to power online searches, web advertising and cloud services. The company has boasted for years that these huge computer-filled warehouses are energy efficient and environmentally friendly. But there's a cost that the company tries to keep secret. These facilities use billions of gallons of water, sometimes in dry areas that are struggling to conserve this limited public resource. [...] Google considers its water use a proprietary trade secret and bars even public officials from disclosing the company's consumption. But information has leaked out, sometimes through legal battles with local utilities and conservation groups. In 2019 alone, Google requested, or was granted, more than 2.3 billion gallons of water for data centers in three different states, according to public records posted online and legal filings.

    The water doesn't just magically DISAPPEAR after being used as a thermal container. How much of this water is returned back into the system? How much of this water is pulled directly from a river then returned to it a little warmer? This is how liquid cooling a nuclear power plant works. Why would it be any different for a data center?

      Also, depending on location, data centers have partnered with nearby other facilities that need thermal energy. This has been used as the heating source in HVAC systems in office towers for example. That water flows through the pipes at one location to the other, allowing efficient heat generation where needed nearby.

        The problem is that a lot of the water is used in evaporative coolers, which vaporize a lot of water, as the name would suggest. That humid air then blows away, leaving local agriculture and municipalities with less water overall.

        As for office heating, I doubt there's much need for that in Arizona.

            Thermodynamics, my friend. Unless they were discharging the cooling tower air directly into a very large greenhouse, you can’t just recover the evaporated water. Some of the drift can be recovered, but that is insignificant. You can also recover blowdown water, but that is a small percentage of the total.

            For a sense of scale, a million gallons of water a day is enough to water a greenhouse that is one square mile ground area.

            • Even if you recapture the steam, to get water again you have to extract the thermal energy... and that leaves you with the initial problem of "what do I do with all this really hot coolant?"

            They do. The datacenter discussed in TFA is in Arizona. Most likely the datacenter is to serve Southern California, but they don't want to locate it in California because of CCPA and other regulations.

            But even in Arizona, a million gallons isn't that much water.

            TFA says a million gallons would create a pyramid "thousands" of feet high. Actually, a 4 sided pyramid with a volume of a million gallons would be 73 feet high.

              Absolutely. In Arizona [azwater.gov], agriculture uses 74% of water. In California, it's around 80% for agriculture, although farmers will claim agriculture only uses 40%, with 50% used for environmental purposes, i.e., taking water from nature and putting water back into nature.

                A pyramid containing a million gallons of water and another million gallons of air would be 92 feet high.

                A pyramid a thousand feet high would contain 2.5 billion gallons of water.

                  For a pyramid that you might build, you are correct because you actually know the difference between a pyramid and a triangle. Unfortunately, the original article used the word pyramid when they actually meant triangle, which can be seen in this photo [assets.bwbx.io] from the original article [bloomberg.com]. So, keeping with their 2-D pyramid, i.e., a triangle, with proportional base and height, the 4-million gallon structure would tower over 500,000 feet high.

          Water's heat of vaporaization [engineeringtoolbox.com] for an evaporative cooler at 20-25 C is about 2450 kJ/kg. That is, each kg of water that's evaporated yields 2.45 MJ of cooling.

          A billion gallons of water weighs 8.34 billion pounds, or 3.78 billion kg. Evaporating it would provide 9.26x10^15 Joules of cooling. Divide that over a year (31.5 million seconds) and you get 293 MW of cooling. In 2011, all of Google's servers worldwide used a combined 260 MW [nytimes.com]. (If you project that out for a year, that's 2.28 TWh. This government report [lbl.gov] says all data centers in the U.S. used 70 TWh in 2014, so the figure appears to be in the right ballpark.) So if all of of Google's servers worldwide were being cooled with evaporative coolers, they still wouldn't use 1 billion gallons in a year.

          So the vast majority of this water is probably being used as OP surmised - cooling, then being dumped down the drain or reclaimed for secondary use in irrigation. Not in evaporative coolers.

          The problem is something my sister remarked about when she moved from California to Arizona. I walked my dog while visiting her in Phoenix, and was surprised by the huge number of grassy green lawns, many of whom were running their sprinklers during the day (a faux pas in California because a lot of the water evaporates - we're supposed to run our sprinklers at night). She explained that water is dirt cheap in Arizona. The Colorado river runs through Arizona before it hits the California border, so Arizona gets priority in using its water. And boy do they take advantage of it. Despite being in the desert, Phoenix has surprisingly average prices for water [wp.com], especially compared to California.

          If you're worried about water wastage in Arizona, Google is (literally) just a drop in the bucket. All of Arizona (and Nevada/Las Vegas) is profligate in its water use [arizona.edu]. There's no point trying to be water-efficient by using evaporative coolers, when you can just dump the heated water down the drain and get new cold water cheaply.

      "How much of this water is returned back into the system?"

        Almost none. It's evaporated into the air, taking the thermals with it.

      "How much of this water is pulled directly from a river then returned to it a little warmer?"

        None. Google looked at doing that to the Columbia river in Oregon, but the temperature rise it'd cause was deemed as dangerous to the fishing stocks and so it was not allowed to.

      The one exception is the DC in Finland, which is adjacent to the sea. They can pull and dump the thermals into the sea directly, as obviously the ocean has more thermal capacity than a single river.

      "This is how liquid cooling a nuclear power plant works. Why would it be any different for a data center?"

      because power plants are public utilities and Google isn't. What's good for the public isn't necessarily allowed for a private enterprise. Also I don't think that even power plants are allowed to be constructed to do that anymore, as it was realized as being too damaging to ecosystems.

        That means that the Google data center will use between 4 and 16 golf courses of water each day.

        Pool usage, however, is a much lower number. It is found that each pool uses about 15 gallons per day. That means that it takes about 16,000 pools to equal 1 golf course, or 67,000 to 267,000 pools to equal 1 data center of water usage.

    If they are doing it once through and out, whoever granted the permit needs to be flogged.

      The problem is easily reached water that doesn't cost too much to make drinkable. We have the oceans, but desalination costs money and that only works for coastal areas unless you also build a very expensive pipeline. Arizona is mostly desert, so there's not a huge amount of water in the area.

      In other places, there is enough water overall, but there are rainy times of year and dry times of year. The more fresh water is used, the bigger the reservoirs have to be to have enough during the dry times.

      • So it's really just a cost issue. We're not conserving water because there isn't enough of it, but because it costs a lot to make drinkable, store and distribute. And that becomes a political question about who is supposed to pay for it.

        To me, that seems like a very minor problem in the world. Outside of political bickering, nobody is running out of water. Some people just have to pay more for it.

          Fine, you can pay $20 per gallon and never shower again if you like, but the rest of us would like to be able to afford water. The costs go up fast when you need to expand supply in some places. If the large scale users would like to foot the bill for vastly expanding the supply, that's OK too, but they keep trying to push that off on the people consuming within easy natural availability. Same old story, privatize the profits, socialize the costs.

    • Ask the people that live at the mouth of the Colorado River.
      • I understand what you're trying to say here. Some locations are fortunate, some are not. But it's not lack of water in the world. It's lack of even distribution. And that is just a cost/political issue. An issue that seems very simple to solve. If you want to live in the middle of the Sahara desert, water is going to cost a premium because it comes from other places.
    • But few are willing to call it a "problem" at this moment.

      Just watch this 2016 PBS documentary [pbs.org]. There are people living out in rural Arizona who have to keep digging deeper and deeper wells to get water out of the ground, because it's being sucked up faster than it's being replenished, much due to farming. That's your canary in the coal mine. Just like the boiling frog, most people don't see it as a problem this moment, because they're still getting water from the tap. Sure, right now, lawns are green,

    It's Google. While they're notably more evil than they used to be, they're not Exxon. If I were them in Arizona, I'd be using either non-potable water from saltwater aquifers (despite the additional expense in dealing with the corrosion) or building all of my plumbing to potable water standards and returning it to the municipal supply after it runs through the cooling loop (again, in spite of the somewhat higher expense).

    Outside of Arizona, it's largely a nonissue. Their datacenters in Washington state get both power and water from the Columbia river. When you're tapping an entire river for coolant water, your water usage is utterly irrelevant. There's more available fresh water than anybody knows what to do with.

    Water is one of the most strictly local resources on Earth, the pipeline from Colorado to California notwithstanding. It's incredibly heavy. No one with any sense moves it any farther than they have to before using it. In consequence, in the US water usage standards that are sensible in Arizona or California or Colorado are laughably stupid almost anywhere else in the country. In the Midwest, cities tap the entire watersheds of the Missouri, Illinois, Ohio, and Mississippi rivers, such a colossal amount of water that only the Army Corp of Engineers really grasps how much it is.

    In short, Google's 2.3 billion gallons of water usage in three different states is meaningless unless you say WHICH states. Washington state? Shut up and go home. New York state? Go have a look at Niagra Falls, and then shut up and go home. Arizona's 4 million? Out of 2300 million? Shut up, you're boring, stupid, and innumerate, and we're tired of your useless fake enviro-wankery articles like this one.

    • Also, just a note, it's improbable that Google is permitted to tap the aquifer and drill wells. Even homeowners that want to cannot, by law. And that's not the water you want to drink or even use to cool with. It needs some work.

    • What pipeline from Colorado to California? The Colorado River? Which is quite horribly oversubscribed in terms of committed use vs. available flow? You haven't heard that Lake Mead is slowly draining away?

      Then: server cooling is, as others have noted, consumptive. Much of the water is evaporated away. What remains is quite contaminated by chemicals used in the cooling system, and has to be disposed of carefully. This isn't, as with coastal nukes, a case of running the water once through a heat exchanger and

  • As I noted elsewhere it seems that this water is boiled/evaporated to provide cooling for the data centres.

    I would think that there are other ways to dump the heat that would be beneficial to the communities that these server farms are located in - this amount of water should at least be used for farming, in the worst case. I'm sure all these methods would be more expensive but as a member of the community I would think it would behoove them to consider those approaches first.

    Google, you should be doing be

    • How much of the evaporated water is released into the atmosphere versus re-condensed? You are assuming that all of the evaporated water is somehow magically teleported into a black hole. If it's re-condensed, then it'll be pumped back out as reclaimed water. Even if it's released into the atmosphere, it will still re-condense and become rain. So at some point the water will be reused.
  • Conservation is for consumers, not corporations.
    • Don't give anyone a special deal and make them all pay the same rate and the market will work the problem out. When anyone (whether individual citizen or corporation) has to pay for the costs of their own utilization the resources then they tend to be less wasteful. Refusing to subsidize anyone actually drives conservation because reducing usage becomes a larger cost saving factor than it otherwise would if special rates are given to a select few.
  • You act like 2.3 billion gallons is a lot.
    It really isn't.

    "2.3 billion gallons of water for data centers in three different states,"

    come on.

  • So why are we just talking about Google here? We use these services. we are just as guilty of waste as the companies that provide us these services. Seems like a pretty narrow minded discussion here with regard to the wasteful use of water.
  • If they are really wasting so much valuable water, why not raise the price for water to the value of water? Then they can decide whether to pay or not.
    Does it really have to be more complicated than that?

    • Sounds like the town is giving them a huge break on the price, for the "prestige" of having a Google data center in town -- and presumably the promise of some jobs. Unfortunately such deals frequently fail to bring the economic benefits they promise.

      If that's true, and they're not paying the full cost of what they're taking, you could expect homeowners water bills to rise to cover the difference.

    If the water is being used for evaporative cooling in drought stricken areas then there needs to be a hanging. I can't imagine how it is used in power generation. Solar pv and wind don't need water last I checked. Further I don't see how they need fresh water. If it is used for some process then I don't u

They ignore the fact that the site is currently irrigated farmland which, big surprise, looses about an equivalent amount of water from plant transpiration ( which is enormous in a desert climate ). Also, they negotiated water rights, which usually dictate how much you can store.

    Thousands of feet high? Really? Pyramids tend to have their length and width equal to their height (so they are self-supporting). There are about 264 gallons per cubic meter, so 1 million gallons would be about 3800 cubic meters. That would be a pyramid about 23m on a side, and 23m tall. About 75 feet tall. Hardly "thousands" of feet.

    To be "thousands of feet" high, let's assume it's 2,001 feet high. Just enough to make it into the "second thousand" to qualify as a plural. The base would need to be about 14 feet x 14 feet. That's a "pyramid"? It's more of a VERY, very slightly narrowing pointy stick. Not a pyramid.

  • The goal was to show residents of this desert region how much water they each use a day -- 120 gallons -- and to encourage conservation. "We must continue to do our part every day," executive director Warren Tenney wrote in a blog post.

    I have a suggestion - move to some place that's not a fucking desert.

  • Chillers work similarly to swamp coolers, the energy magic is in the state change from liquid to gas (steam). There is a pool of water that is recycled until it evaporates off. As it evaporates off new water enters the pool. The water can be very nasty - see Legionnaires' disease. But the water leaves as vapor, never liquid so there is no chance for reclamation. Best if they are using gray-water.
