A lot of the golf courses around here use reclaimed water (treated effluent). Hopefully data centers aren't using potable water.

They hook into industrial water supplies (usually not potable, unless the utility has no other option)

I would say that is the exception rather than the rule (potable is normal).

You can drink it, but the utilities don't rate it for that / guarantee (complete) treatment, IIRC.

Lake Las Vegas, the biggest user by far, is at 82% reclaimed. The Las Vegas Valley Water Authority's name-and-shame list for water use is still FOIA-able (last year's, obviously). https://archive.org/details/top-commercial-water-users-south...
