I find it weird how this becomes problem for datacentres specifically, as if they are the driver behind this. As a rough calculation, if every datacentre in the world moved to Florida and relied on evaporative cooling, water consumption would be 1/3 of its agriculture or 2x its lawn irrigation.

Datacentre water consumption 500 TWh/y divided by 2.2e6 J/liter latent heat. 500 TWh based on IEA Flroida usage from this doc, table 1 pubs.usgs.gov/sir/2019/514...
