Isn't most of this water reused and recycled through the cooling systems, therefore making the actual water usage much lower?
> City officials were ordered by Google to argue in court that Google’s use of scarce public water was a “trade secret”. After more than a year of proceedings, city officials were forced to tell their own citizens how much public water Google was using.

Idk. If the water was reused it sounds like something you'd brag about it as part of a sustainability marketing campaign.

If the water wasn't reused it sounds like something you'd try to bury.

There are even places where water use is, really, not a big deal. My city pulls 100% of its water from a river. Sewage, after treatment, goes in the same river. Unless we suddenly grow by an order of magnitude, we are not putting any stress on the system.
Its about the water-meter before the datacenter. So 1000 liters in - thats 1000 liters of "use". If you re-cycle it a 1000 times, still only a 1000 liters on the meter.

Since water isn't pure from public system, well, you can create "life" if you keep it warm just long enough. So you better replace/mix it with fresh water. So another 500 liters? Now we're at 1500 liter total.

Rinse and repeat.

1. A good bet "potable" isn't a requirement for whatever spent water is discharged from data center cooling systems (only potable water should be in drinking water pipes anyway). 2. Warmed water holds less oxygen, which negatively impacts the water source's ability to sustain life.
