Because that's expensive to build on this scale. They'd have to cool the water back down again.
It's cheaper to just run cold tapwater in at a fast rate, and dump the hot water intothe sewer.
Which is why we need laws that go after industries that use insane amounts of water, if we don't it causes shortages and everyone's rate to go up
There should be a cost to corporations using municipal water supplies for purposes unrelated to direct consumption for drinking, cooking, washing, toilets. You shouldn't be able to use it for cooling only, and you shouldn't be able to bottle and resell it.

We should make it exponentially more expensive the more you use.
There's probably some alternate uses for the heat if these things were well designed. There's some building in denver that is near a major sewer and in the winter they use a heat exchanger to extract that energy and use it to heat the building.
Nah, it's because of the volume.
You don't cool down hot water with the same amount of cool water. You use a shit ton of cool water, because the larger the difference in temps the faster the heat exchange.
So the discharge isn't water that's really hot. It's just warmer than when it went in.
Maybe 5-10 degrees, which is enough for a negative environmental impact if constantly discharged into a lake/ocean/river, but not hot enough to be good for anything.
They could do large underground reserve for cold water, cool their servers with it, then dump it into a second tank that eventually cools and is added to the reserve. It's not complicated, but it is a huge upfront cost.
Companies aren't going to do it when they can pay a fraction of the cost even tho it fucks over everyone else. This is capitalism, we need regulations forcing them to do the right thing over the cheap thing.
I suppose that's very true. But it could be done - if a data center needs megawatts of cooling and is in an area where buildings need to be heated in the winter, then there should be a legal obligation to not just dump that heat.
Pumping 80 degree water outside of a building in winter isn't going to help anyone...
That's right in the range for subfloor heating, obviously a question of whether or not you can get it somewhere that you need it
