Now this is a wild take.

being used as a scare tactic by groups opposed to data center construction
It isn't a scare tactic. It's a real concern. They need to be either air cooled, geothermal cooled ( lol ) or raw water cooled. Raw water cooling is tits, it just restricts available locations dramatically. It also drives up land cost, because there's usually more people and consequently higher cost where there is water.
For the record, I do (indirectly) end up with money in my bank account that is directly tied to data center construction. I benefit from it. The uproar over water usage is a good thing. There is uproar over power usage as well, also totally valid. The talk of powering them with nukes is great, except that also can consume colossal amounts of water, depending on how it's done.

Raw water sucks as coolant.
Several power plants in the are use raw water as a once through cooling source. The idea of a radiator is pretty interesting, in the river direct or sitting into a diversion tank or something. There's something there.

That's how large equipment is cooled on ships. It's extremely efficient. It's basically the only type of cooling on earth where you get an infinite heat sink that does not require any type of forced fluid movement on the sink side. Even in stagnant water, you get convection current over the cooler.
It's called keel cooling in the boat world.

This doesn’t mean that their water use is nil. What is actually being used to reject the heat to? Air?

Well let's just say this, water doesn't magically disappear from earth.

im conservative and a capitalist and In tech who makes money with ai and even I think this is moving to fast. its not just water it’s electricity and noise pollution. these things have a constant hum

But but but it all goes back into the water cycle
Yeah...that's always been a silly argument. The existence of the water cycle doesn't mean that municipalities can't have real water shortage issues.

will data centers that use way more water than that be placed under the same restrictions ?
90% of water usage in CA is agriculture or industry. Yet the only ones who get throttled are homeowners. What do you think is going to happen?
If a data center is going in near your house you might as well start planting “native” plants.

I attended a Q&A session last week with a Meta rep about the DC they are putting up by Monroe. The question of water usage was brought up by several people and at no time did the rep ever mention any of the points you bring up. Never mentioned closed loop systems for water effeciency, in fact did bring up speciffically that they were working with local entities to upgrade waste water facilities to handle what the DC would generate.
You would think if this was such an important issue to people, Meta would want to let them know how effecient they plan on being with the water supplies.

It certainly does not magically re-deposit into the aquifer either.
The whole "water cycle" argument is ridiculous.

Man, you solved the problem.
We'll just build all the data centers on barges and float them out into the blue stuff and use the blue stuff as a heat sink!
They can be accompanied by barges of solar panels to power it all!
It can all go far enough out into the blue stuff to where the people can't see it!
It's a hippies wet dream!
It'll totally work great!
I love how global warming and rising sea levels is all of a sudden totally not a concern for anybody anymore

That we're going to accelerate the melting of the ice caps???
I know what you were getting at, but I feel like the ice caps is a more funner discussion to have.

One of the data centers in Louisiana will have 3 power plants built to support it. Payoff on those plants is 45 years and the company is only paying for 15 of them.

Why? The data center is going up no matter what. Neither Meta nor the local government officials that are bound by NDA give a shite what the people want.

META just upped their infrastructure investment from $650 million to $2.65 billion, pending PSC approval. Honestly that goes a long way towards easing my worries.

Everything I’ve read is that Entergy claims the new deal with Meta will “deliver approximately $2.65 billion in total customer benefits over two decades” (quote from WBRZ article). Not that Meta is investing $2.65 billion in infrastructure.
I don’t really know what “delivering $2.65 billion in customer benefits” means. Do you? It’s all deliberately obscure. Even if that were Meta’s actual contract value with Entergy, I’m not sure how anyone could possibly determine whether that’s good or bad for the rate-paying public without the full details being released.
