You ever notice how many ponds are on a golf course? Any excess water from sprinkling drains to those ponds, instead of off of the course. That is then reused.

There are also reservoirs under tee pads used to keep evaporation down.

And finally, very nice courses use underground systems like SubAir that pull excess water away, oxygenating the soil to promote growth with less water and saving the excess water for later.

Golf courses try very hard to prevent water loss from evaporation. It’s why you see so many damn sprinklers on a golf course. The more sprinklers reduce the distance the water has to travel, reducing evaporation, and also results in more even coverage meaning less water loss to runoff. Golf courses aren’t tech companies. They don’t just throw money away trying to capture entire countries markets, they have to function in society in a very visible way as being seen as wasting a lot of water.

Data centers don’t have to do any of that, and big tech companies get free passes to do whatever the fuck they want no matter how bad they’re fucking the environment.
