We don’t know how much water data centers use. We just know it’s a lot

Why would a data center need to continously consume water to cool itself? Leaks?

[–] [email protected] 4 points 1 year ago (3 children)

When calculating water use, it's important to not only look at the water used directly to cool data centers, but also at the water used by power plants to generate that 205TWh.

The researchers also tracked the water used by wastewater treatment plants due to data centers, as well as the water used by power plants to power that portion of the wastewater treatment site's workload.

They compare it to residential use and I wonder if they add all those sources for that when comparing?

[–] [email protected] 1 points 1 year ago

For California at least, residential use is about 10% of all water usage iirc. So if data centers are dwarfed by that...not a big concern in the big picture.

The issue I guess is when data center usage sucks up all the local supply. State and region wide they don't use much but they do use a lot in one small area.
