Figured it was the government. Thanks.
Averages are funny things.
Obviously everyones habits are different, and thus their water consumption. I am quite sure an environmentalist who only flushes after #2 and has a cactus instead of a lawn uses less water than a guy with a big green lawn who takes baths and runs the water when he shaves.
But I haven't met many illegal alien environmentalists... so I am going to guess they are at least average in their water consumption.
