I don't understand. where does the water go? are they using evaporative cooling?
Depending on the local climate, yes - evap cooling is typically the go. The data centres I work in here in Melbourne use evap free cooling (EFC).
For much of the year, due to our temperate climate, the cooling simply uses (filtered) outside air. During bouts of warmer weather (typically 29C+), we use evaporative cooling. Waste water from the EFCs is discharged into storm water drainage, and reported to our local water authority for billing.
This might be a stupid question, but I wonder why they (datacenters) can't recover the water they use especially if it's in the order of magnitude that it significantly impacts water resources in their area.
I might be missing something big here, but I am imagining water-cooled systems that transfers heat to the water, but the water is otherwise unused. This water might not be able to be fed back (to the water sources in the area) as is, but it can be cleaned up and cooled down, and then be used for other purposes, right?
An excellent question, that I suspect the answer to will vary in many jurisdictions.
We do re-use the water we use in our EFCs, but only a limited number of times. After a specified number of uses, local regulations require that we discharge it into storm water, to mitigate against the risk of things like legionella and other potentially deadly airborne bacteria.
We’re also required to test and treat all stored water monthly.
