2.5 billion gallons per year.

The US uses about 2 billion gallons of water per day on golf courses.

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)

[matt-p]

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

[nevir]

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...

The more important question in both cases is where the water comes from.

[myaccountonhn]

And how it affects the local area.

An industry report from 2012 puts water use for US golf courses at around 2B gallons of water/day [0].

It's possible they've gotten more efficient in the past 14 years, but it's also possible there are more golf courses today. I haven't looked into it.
