This is one of the data centres that went to the extra expense of building a closed loop cooling system that would, supposedly, not waste water on a continuous basis. Apparently, even these are not so clean to set up. Governments are going to need to start paying more attention to the commissioning process apparently.
--------
"Meta said that it's supporting its general contractor, Fortis, which stopped discharging and began hauling wastewater offsite"
--------
Governments should also watch where this wastewater is being hauled to, and likely just dumped.
This closed loop system needs to be filled and flushed, which is the operation discussed in the article. The bacterium was described as a possible airborne hazard if used for irrigation, it's not a regulated substance though so dump and dilute might be perfectly safe.
Testing for an extremely
rare bacterium is not the bare minimum. In fact even the water treatment plants rarely do it. They admit in the article we don’t even know whether or not the bacteria originated from the water supplied by the city that entered the pipes in the first place.
DCs should be responsible for their output but this seems to be a super edge case.
Not do what? Not discharge the water with bacterium? But the data center claims that their independent testing shows that they didn’t even discharge the bacterium. It seems that neither the city nor Meta knew where the bacterium came from.
By definition, externalizing a cost is less expensive than internalizing it; the only recourse for the rest of us is forcing them to properly internalize their costs.
As a former microbiologist, this news is important but not too concerning. It’s good that we found detected this and can respond accordingly. It doesn’t mean indicate an immediate, critical issue.
Since the article doesn't make this clear, let me explain.
The cheapest (and worst) option is to take in water, use it for cooling and then dixcharge it. Why is this bad? Because DCs don't want to corrode their pipes with untreated water so they add coolant and additives to it, which pollute the water. This is bad. But nobody really does this because you don't want to keep adding additives to water you're constantly discharging.
The next step up are varying degrees of what's called "closed loop" cooling. That is, the DC has treated water in a closed loop that isn't discharged. There's a heat exchange system with external water. This btw is the system that's used in nuclear reactors although nuclear reactors will be far more stringent than DCs are. Best practice for this is one of Google's DCs in Scandanavia that uses ocean water for heat exchange. There are limits to this but there's only so much Arctic Ocean water a DC can meaningfully heat. It is potentially disruptive though and that needs to be considered.
Even so pipes will need to be cleaned. There is debris that builds up and in cases like this you can still get bacterial outbreaks. This is another reason to use additives like chlorine. But again, you don't want to discharge chlorine into bodies of water.
I'm reminded of water management in the Yukon. The Yukon for over a century have been gold fields. If you look at the tech required to extract a tiny amount of gold from a large amount of earth, it's kind of fascinating but it boils down to using a lot of water and having the denser gold sink and get trapped.
So gold miners take in water from rivers, wash rocks with it and then have historically just discharged it back into the rivers. This tended to be heavy in silt that would go into waterways and could create problems. The water was also dirty. So the Yukon authorities have gotten increasingly stricter with water management. Now water has to go through a series of settling ponds so the discharged water is clean/clear.
I kinda think we need similar levels of strict water management for DCs. No discharged coolants and clean water. Figure out how to get that. If that makes your DC more expensive then that's a "you" problem.

This is why datacenters in central texas are desperate to build anywhere in the edwards aquifer... so they can get "free" water from natural springs (already stressed by draught) and dump the effluent into city wastewater systems.
Data center water use is a fairly separate topic from what this article covers. Related of course but the conversation on USE centers around actual volume use, not contaminants.
It’s not a separate topic though, as this article shows. A closed loop system can still mess up the water supply, because (in this case) it wasn’t fully closed.
According to the article this is a closed loop cooling system, once it’s up and running it doesn’t use any water. They run water through it during installation and that’s the discharge that they found bacteria in.
You can have a “closed loop system” but you need to shed heat somewhere and that is either by air cooling drawing tons of electricity, or evaporation that draws tons of water.
it's not a consolidation because all those computers are still in office parks and the like. This is new usage, and it consumes exponentially more resources than all of the previous usage.
You're describing a shift from a decentralized system with autonomy and competition everywhere to a centralized system where a few tech billionaires control everything.
All of these guys benefited from owning computers and using the computers owned by universities and now they're trying to convince us we should pay them for every bit that gets processed.
No thanks. I don't want that. I'd rather see the tech industry collapse and go back to pen and paper.

Man, I wish I had more downvotes. This is not just about consolidation, it's about massive resource usage in areas where hardly any of the benefits accrue to the locals.
Just look at the proposed data center in Utah. It was originally proposed to be larger than Manhattan, use more electricity than the entire state uses, in a place that already is suffering a water crisis. And for what? So a few connected politicians can get bribes, and AI money can be made by people thousands of miles away, while meanwhile AI takes the jobs from people that actually live in Utah (not my words, these are the words of folks like Amodei and others actually building this stuff).
Pretending this is just a consolidation of servers currently living in office closets is laughable.
People would love to build their own servers (and run AI or other workloads on them) and kids would love to build their first PC, but big tech is buying all the hardware and stuffing it into data centers. You make it sound like they asked for it.
How do I, as an ordinary person, benefit from Meta's data centers? I don't have any presence on Meta's platforms & the only time I even notice their existence is when someone sends me a text message via signal for some viral link on one of the social networks.
I think you're overestimating the relevance of these data centers for regular people. They can get by just fine w/ local¹ & a lot less environmentally destructive computational resources.
I've never seen a cent go to any service in my local municipality from Meta's taxes & whatever does end up in the city coffers is not big enough to have any real effect b/c those services could just as easily be financed by direct payments instead of some circuitous route of federal, state, & sales taxes from transactions enabled by corporations like Meta.
If I was in SF & working for Google or Meta then maybe you might have a point but I'm not in SF or any major metropolitan area so from my perspective the whole thing is actually a net negative.

Brief google search shows that most Meta DC's give around ~15M per year taxes on average per year. I'm not sure what circuitous route you are speaking about.

The amount I showed was after accounting for the Tax abatement program. And its almost as if there's a reason the state wants to have this program in the first place. Almost as if it helps broader society.
People in London buy Instagram ads to sell products to people in Birmingham and that money comes into the US. There are plenty of ways for you to catch some of it.
This is downvoted but factually correct way of looking at it. The benefits of Meta are convoluted and hard to state in ways that are quantified to simple numbers. (Well you can - Meta contributes ~0.25% of USA's GDP which is enormous)
For example, what is the benefit of google existing? Sure you can do google searches. You can use maps. But can you quantify it?
The benefits of living in a society that respects pluralist values is that even if you personally have never used Instagram ever, you still respect what it provides for broader society.
Its easy to give a popularist argument against anything you don't like - "how does it benefit me?!". Well it need not, but others use the products.
On a side note: I'm glad to live during times where we respect pluralist values. I hate football and find it mind numbing. But its great that those people can have their fun and joy without having to convince me. And I can have mine with League of Legends.
I always imagined the HN server running on a single machine in some basement, running a magically efficient Lisp program that easily handles millions of requests per second.
HN supposedly currently runs via M5 Hosting according to https://news.ycombinator.com/item?id=45750668 (comment from late 2025), though I think it ran on a single server over a decade ago.
Does dang run HN on a single server? Why does HN use Algolia for search and Firebase for its API?
"Using an old phone or laptop as server means you'll end up with a single digit annual electricity bill for that."
The largest possible single digit annual electricity bill would be $9. That's almost enough to run a 3W device 24x7 for a year. Do you know any old phone or laptop that can serve as a reliable Jitsi server yet draws an average of 3W or less?
Is it really that expensive to not do stuff like this?
I guess 'turning the entirety of the American public against data centers' is not something they factor into the cost analysis.

Everyone saying stop talking about data center water use is missing the entire point as this article shows.

Discharge, is part of "water usage". Arguing otherwise is embarrassing.

You can have a “closed loop system” but you need to shed heat somewhere and that is either by air cooling drawing tons of electricity, or evaporation that draws tons of water.
From the links in the article, it looks like this DC runs giant heat exchangers to dump the heat to air.
I’m pretty sure that “closed loop” in this context would mean that the water is recirculated and not evaporated.
