What it sounds like is the data centers are using untreated river water, and then are wanting to put that untreated (and now hot) water back.
This is better than using municipal water, which goes through expensive treatment to make it safe to drink.
I would hope they would have a reservoir to cool the hot water before dumping it back into a river. I can't imagine hot water being healthy for life in the river.
It’s called thermal pollution and no it isn’t.
You'd think that once the water is cooled, you could send it through again.
Yes. there are stipulations in the draft water about maximum withdrawal from surface water sources and required continuous monitoring of water temperature of the discharges.
