This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Sure whatever. Heat exchanger is heat exchanger.
...until that one breaks.
Then it's a shit storm.
I assume it's relatively clean, but not safe to drink
Edit: I don't think the replies are really getting it. This sounds like a great use of minimally processed water with relatively small risk. It's much better to use this water than potable water for the same purpose, assuming water is going to be used no matter what.
Depends on the amount of treatment steps it undergoes.
Standard procedure is aimed at just removing solid debris and organic matter, to return clarified and chemically balanced water to nature, with no excess nutrients that could feed algae in water streams.
From that point forward, it is just a question of how far the treatment can be taken.
For reuse for cleaning, washing, etc? Maybe it just gets a minute dosage of sodium hypocloride.
Highly sensible areas, like beaches or lakes? UV treatment, maybe followed by micro filtering. Extreme scenarios? Reverse osmosis.
If the protocols in place are strong, it's safe.
