Even with that incredible waste....we still save more than we promised to. And besides......the casinos aren't paying for the extra high water bill....the tourist are. (seriously, I have a friend that works in engineering at one of the hotels....he says they have three guys that maintain the systems for recycling their grey water for the many water features on property. Its not water you'd want to drink but it isn't fresh, single use water either.)While not exclusive to LV, having those fancy fountains shooting water up into 115-degree air isn't a good visual for sure.
