Yeah the thing about the closed loop systems is that they pump a shit ton of chems to kill anything in the water. However no matter what shit grows in the loop. So they end up flushing the loop and dumping the water and chems into the sewer, before repeating the process.

So no, closes loop DCs aren't great.

And i literally work in one. Just the other week the DC manager told me they had a leak. A stupid amount of water was lost.

But because water is so cheap for commercial metro users it was more a oops then a wake up. Bare min repairs and bam, back up and running.

The point is these "closed" systems aren't perfect and shit happens. Especially as they age out.

That's only if the system doesn't use evaporative cooling, which most of them do since it requires a lot more cooling infrastructure to not rely on evaporation. Instead of the water evaporating in the cooling tower it'd have to sit for much longer in a cooling tank to allow the heat to radiate away, and that's a very slow process.

Are you a bot? Or just a paid shill? You can just do a miniscule amount of searching to find closed loop systems are extremely rare in America due to the costs. Its much easier to just steal and polute potable water

Le sigh.

Large data centers can consume up to 5 million gallons per day, equivalent to the water use of a town populated by 10,000 to 50,000 people. -source
