I believe evaporative cooling is the norm (thus my "possibly many times that" remark doesn't apply) however theoretically they could provide hot water as a utility or (as you say) just dump it into the sewer. If located next to a river or the ocean they could conceivably dissipate it that way but I'm not aware of any examples.
It's the sort of externality that could be solved with a well placed megaproject. A related question to my mind is why we're building such expensive strategic assets in the open rather than under a mountain.

> under a mountain
Delved too greedily and too deep learning!

Evaporated. Given how the water cycle works, it should be expected it will be precipitated back as rain.
With the catching being of course that it won't end up where it was being pulled from.
