How AI is Taking Water From the Desert (msn.com) 108

Microsoft built two datacenters west of Phoenix, with plans for seven more (serving, among other companies, OpenAI). "Microsoft has been adding data centers at a stupendous rate, spending more than $10 billion on cloud-computing capacity in every quarter of late," writes the Atlantic. "One semiconductor analyst called this "the largest infrastructure buildout that humanity has ever seen."

But is this part of a concerning trend? Microsoft plans to absorb its excess heat with a steady flow of air and, as needed, evaporated drinking water. Use of the latter is projected to reach more than 50 million gallons every year. That might be a burden in the best of times. As of 2023, it seemed absurd. Phoenix had just endured its hottest summer ever, with 55 days of temperatures above 110 degrees. The weather strained electrical grids and compounded the effects of the worst drought the region has faced in more than a millennium. The Colorado River, which provides drinking water and hydropower throughout the region, has been dwindling. Farmers have already had to fallow fields, and a community on the eastern outskirts of Phoenix went without tap water for most of the year... [T]here were dozens of other facilities I could visit in the area, including those run by Apple, Amazon, Meta, and, soon, Google. Not too far from California, and with plenty of cheap land, Greater Phoenix is among the fastest-growing hubs in the U.S. for data centers....

Microsoft, the biggest tech firm on the planet, has made ambitious plans to tackle climate change. In 2020, it pledged to be carbon-negative (removing more carbon than it emits each year) and water-positive (replenishing more clean water than it consumes) by the end of the decade. But the company also made an all-encompassing commitment to OpenAI, the most important maker of large-scale AI models. In so doing, it helped kick off a global race to build and deploy one of the world's most resource-intensive digital technologies. Microsoft operates more than 300 data centers around the world, and in 2021 declared itself "on pace to build between 50 and 100 new datacenters each year for the foreseeable future...."

Researchers at UC Riverside estimated last year... that global AI demand could cause data centers to suck up 1.1 trillion to 1.7 trillion gallons of freshwater by 2027. A separate study from a university in the Netherlands, this one peer-reviewed, found that AI servers' electricity demand could grow, over the same period, to be on the order of 100 terawatt hours per year, about as much as the entire annual consumption of Argentina or Sweden... [T]ensions over data centers' water use are cropping up not just in Arizona but also in Oregon, Uruguay, and England, among other places in the world.

The article points out that Microsoft "is transitioning some data centers, including those in Arizona, to designs that use less or no water, cooling themselves instead with giant fans." And an analysis (commissioned by Microsoft) on the impact of one building said it would use about 56 million gallons of drinking water each year, equivalent to the amount used by 670 families, according to the article. "In other words, a campus of servers pumping out ChatGPT replies from the Arizona desert is not about to make anyone go thirsty."

      It's also worth remembering that Phoenix has done a lot to actually conserve water.

Supposedly among large cities, Phoenix has by far the lowest percentage of lawns in spite of having a lot of housing. They also have long required that new projects for building housing secure water for next 100 years. Recently they just stopped issuing permits

      What you are talking about is referred to as a "dry cooler". In that case the water has to be hotter than the outdoors. So the water is going to have to be 120F, possibly hotter than that. And that means you have to have chips that can withstand temperatures of 120F (or hotter).

      As the other commenter noted: Evaporate cooling in cooling towers is reliable and dependable. And it is doubly dependable in extremely dry climates. The only trade off is you need water equal to your heat generation. And that water is on a one way trip. And this is easy to set up, you inject city water into the loop, cycle it through the cooling tower, let it evaporate and refill it with more city water.

      The only way I could see "Dry coolers" working is to get water-to-water chillers operating that can discharge the heat rejection side to over 120F. But at that point, you might as well just go directly to direct expansion cooling. And the reason data centers don't use that is it is much more power intensive. Cooling towers are cheap to operate as long as you have an infinite supply of water.
      • Why not run the potable water through a heat exchanger and return the city's water back to the city but slightly warmer? Use the city's water pipes as a giant reverse geothermal heat sink? Datacenters get cool servers, thousands of people get to take showers and flush their toilets. Everyone wins.

          Well I don't think you understand that scale you are talking about.
          For example: The city of Toronto uses a great lake for cooling for its NBA arena.
          But if you wanted to use city water that you pull in and then reject back to the city to be used elsewhere. Lets assume you have a "small" data center with a 100 tons of cooling load (12,000 BTUs/hour *100) with a total of 12,000,000 BTU/hr. Water increases temperature at 1 degree F per pound of water, so (very roughly) 8 btus per gallon per degree. So lets assume we heat city water by ten degrees (that keeps us well below legionella). (insert a bit of math here I am not going to try to show in HTML): That means this "small" data center needs to pull 2,400 GPM, all the time. And the new water has to be reject its heat someplace or it is going to be pulled back into the data center having been warmed up. So at 4am when everyone is asleep and this data center is still operating, it is still going to be pulling 2,400 GPM and the water in those lines is going to get warm because no one is using the warm water.
          And remember that all of this water you are piping around has to be piped as if it is potable water - because you are claiming it is still potable. That is likely to stomp on this right there. I suspect most city water managers are not going to allow anyone to inject untested water back into the drinking water supply for a city.

        Modern chips are pushing well over 100C. That's 212F. Their cooling water is usually around 50-60C in home AIO coolers that handle much lower heat loads than server farms.

        Errr that's not bad for cooling water line. "Hot water" cooling systems do exist in many datacentres already since they are more efficient power wise. There are supercomputers in the top 5 list (to say nothing of the top 500) that are "hot water" cooled, and typical computer components can take this temperature quite easily too, especially the chips currently used for AI which don't suffer from the presence of a heat spreader. There are plenty of datacentres which run closed hot cooling loops already.

          In other words, water prices are too low.

          From a strictly free-market point of view you're correct, of course. So let's think about the ramifications of that.

          The current residents are using water. They're happy, their demand is pretty much on par with the supply, prices are low. Then the data center is built. Water prices are low so they decide to go with evaporative water cooling. Now the demand exceeds the supply. But it's a free market, so the prices go up. The company who owns the data center isn't concerned. Water is still priced less than alternative cooling systems. But now, the residents' water bills skyrocket. They're competing with a big company with deep pockets for a limited resource. The company can afford it. The people can't. Eventually people start moving away because they simply can't afford to live there. Yay, free market. Sure, the prices eventually stabilize but only after the demand decreases because so many people have left.

          Or heck, why stop there? The water is from a river, right? Who says it belongs to the townies? Let's just locate the pumps upstream from the town and divert it all to the data center. In a free market, isn't that a smart idea? Why pay someone else for a resource that they're just scooping up from the environment when you can go out and scoop it up for yourself? (We'll just ignore the fact that the Colorado River is already the subject of tons of treaties and regulations shackling the power of the invisible hand. Those are bad things, right?)

            The trouble is that even if you say it does belong to the townies, big data centre comes along and waves a big cheque in front of enough of the townies that they sell up. They then go and live it up for a few years, before realising they have now spent all the money and no longer have any water. At that point they start grumbling about how big business is ruining everything.

          • Actually, in the west there are regulations on who can divert water and how much water the individual or organization is entitled to.
    • The problem is, if you want it to run in a desert, it is going to have to reliably operate in 140F conditions. If the outside air temperature is (OAT) 120F (not unheard of in a desert), that is the lowest temperature the chips are going to see, so they have to be able to operate in conditions hotter than that.

      And that means having huge fans that can draw enough hot air over those chips, and having racks optimized for air flow.

        No one is air cooling GPU/AI accelerator chips. It's been water cooling for at least a decade in data centers. Heat loads are far too much for air cooling.

      Is that wrong? I don't know the situation in Phoenix, but using electricity for refrigeration probably releases more CO2 than using water. It might be more environmentally friendly to divert water from crops to evaporative cooling. Anyone care to math it out?

    • Honestly, though, server should be built to run in 100 (40C) ambient temperatures. It's really not that hard.

      Servers are built to run at temperatures like that. The problem starts happening when you start putting them closer together, next to other servers, in a room. There's no free lunch. If you want more air cooling with higher ambient temperatures you need to increase the datacentre footprint. Something has to give when you trade away any variable in a design.

          They have different needs, as they take waste water from residential. So as any sane regulatory system, they go under a different regulatory framework. For example, they would be required to take waste water, reuse it and not emit it out once it's used up without significant treatment.

          Would this sort of a regulatory regime meet your criteria for a "free pass"?
