besides hygiene, we use water for cooking and cleaning as well. and it's hard to say whether any of that is a truly unnecessary use...
the worst part is that all of the water we use is potable - very few places recycle gray-water or utilise rainwater harvesting. that's a huge expense, to sanitize all this water that's going right back into the ground or someone's toilet.
