"Tons of water" is also a pretty pointless metric used only because it sounds bad if you don't engage a crucial thought process. Tons of what kind of water (raw river water for cooling, or drinking water), and where (River, sea, lakes, aquifer, renewing source or not) and what happens to it (returned to the source, contaminated, evaporated, etc). Some places have so much water that they just let it run into the sea. Almost no water is "lost", except when growing food, when a small percentage of the water used is shipped away within the food.
