Water is great for cooling, but who the hell dumps it afterwards?! I don't think they quite understood what "water cooling" is..

Large scale water cooling systems are open return systems.

Basically they pump in cold water and pump hot water back out.

Cooling the water is expensive and ineffective on large scales.

Beyond that you have evaporative cooling which is used for large scale HVAC systems in this case the water simply evaporates away into the atmosphere.

They dump it because it's not cool anymore and nobody is wanting to buy hot water from them at a cost that makes it worth their while. If they had the capability to cool the water fast enough then they'd use a closed loop cooling system and wouldn't need to pump fresh, cool groundwater.

Well, duh. If I had to pay nothing for water, I would also just run the tap through a radiator all day and save on the AC electricity.

But then I also have a conscience and realize what a gigantic waste that is, so I don't.

Are there any "municipal heating" systems in the U.S.? It's popular in NL, the idea is basically hot (~70 degrees celcius) water being pumped from industrial areas (where it was used for cooling), to residential areas for cheap heating.

Yes, in New York City.

There's one in downtown St. Paul, Minnesota¹, but AFAIK it only serves the downtown, i.e. large government and office buildings and hospitals.

It's how amazon is heating their new buildings in Seattle:

Bang! You're no longer dead! (maybe)

That's exactly what I mean though you posted it with a click-baity lead-in.

Wow, so that's why I've seen steam so often as an element of the NY landscape! Very cool, thank you.

Water has an exceptionally high heat capacity, I get it. But using drinking water to cool our servers (in the interest of seeing the very best ads) seems like an exceptionally short-sighted choice for us to make. If there is a less worthwhile thing for us to be doing with potable water, I can't think of it.

I mean, it's not like the water is being destroyed, or even rendered undrinkable, it's just being warmed...
