It would be nice if it could be cooled using water from the Columbia river instead of from the aquifer...

I only live like 3miles from the data center but am on a different water source. Still, with increasing drought conditions it might contribute to increased costs and availability in the future. I already pay $75/m for water...

It evaporates, the heat is used to evaporate the water.

Do they heat it that much to evaporate a lot of it? I've read about one water cooled DC, don't remember which one exactly. But I do remember they were drawing water at around 15C and returning back to the river at 20C.

They're using evaporative cooling. It isn't just a basic heat exchanger.

Seems like a waste of chlorine & flouride. Why Dalles & not say Hood River 24 mi downriver?

Local resident here: there's a hydroelectric facility that provides a lot of the power for the data centers in The Dalles. More generally, land is more plentiful and cheaper there than in Hood River.

Wildly off-topic but it’s the holidays and there’s a certain sense of community in the air so why not: Howdy neighbor!

This article makes several disingenuous statements to paint an entirely false, emotion provoking narrative. First: Google is not "consuming" water any more than a water wheel or dam turbine "consumes" water as it passes by in a river. This is an objectively absurd framing. Second: Even if the water were consumed, which it isn't, 25% of a town of 16k is not a significant amount of consumption. Third: This article talk…

Where's he water that passes through the facility go? Does it go into the fresh water reservoir for the city, or the sewer, or into a river? If it isn't going directly to the city's residents in some fashion without needing to be treated, I think it's pretty reasonable to say "consumed". To say it more succinctly: the water you flush down the toilet in your house is, in fact, "consumed".

But not consumed in the sense it's gone. It's then cleaned, and reconsumed, and then cleaned and ...

It goes back into the river, of course.

Every drop that evaporates from the reservoir, that would not have from the naked river, is consumed. Every drop pumped out of the reservoir to irrigate desert farms, that could not have been without the dam, is consumed.

And if more evaporates from the resevoir, less outflows to the ocean directly.

None of the Colorado River reaches the sea. In the past, it fed a delta of two million acres of prime wetland, key habitat for migrating birds. Today that is all desert.

The Sacramento River feeds the Sacramento delta, a thriving ecosystem. None of the water that reaches the sea was wasted.

It uses evaporative cooling.

That is water that isn't being released back to the river, or reservoir, or aquifer (from which it came).

edit another source, though a bit old: https://www.datacenterknowledge.com/archives/2008/10/01/goog...

> Data center cooling is usually the area where the greatest savings can be realized. That's true for Google, which describes its use of evaporative cooling techniques, and provides a diagram of the workings of one of the cooling towers at its data center in The Dalles, Oregon.

Still, the evaporative cooling towers are the things that are there and take water from the ground and turn it into steam, released into the air.

Lots of comments here suggesting that the water use is no big deal, but please note that Google is not using river water, they’re currently evaporating 29% of the municipal water, which comes from the aquifer, in a very dry region. The aquifer in question was being depleted prior to agriculture moving to river water and the local aluminum smelter shutting down, but it’s now healthy. Google’s planned use threatens to overdraw the aquifer. To offset Google’s use, the city plans to pump treated water into the aquifer.

But not because of hydroelectric. 0% of the water is "consumed" by hydropower, even if a huge percentage of the water passes through its turbines.

The water is siphoned off elsewhere for irrigation.

Yeah, it looks like some (most?) water is evaporated -- but a significant portion is also returned to the river.

I saw elsewhere that google "consumes" around 4x as much water for hydroelectric power generation as they use for cooling. Hydroelectric will return essentially all the water back to the source.
