Shopping malls in Las Vegas are heavily restricted from using local water in their fountains, so some of them have been trucking water in from faraway (at great cost) just for their fountains. Somehow, this does not surprise me.
The best section of the article though, is this little tidbit of Las Vegas suburban lifestyle:

"I'm a water hog myself. I let the water run when I'm brushing my teeth and stuff," said 24-year-old Valerie Brown. A cocktail waitress, Brown had just completed a shopping run at Boca Park and was waiting for her SUV at the valet stand, outside a Cheesecake Factory restaurant and a boutique called Hottie.

"They should have more fountains," Brown said. "It's a desert, after all. It's nice to break it up."
