Here in the United States we use more water per person than anywhere else in the world. The EPA estimates that the average water consumption per person is around 114 gallons a day. While in some less affluent countries the average is about 2 or 3 gallons a day! And in some drought stricken areas fresh water isn't even available without carrying it for miles. It's great that we are blessed with such an abundance in the US, but using this abundance wisely takes conscious attention. It doesn't seem to make much sense to spend huge amounts of fossil fuel based energy to purify our drinking water only to then flush large amounts of it down our toilets and send countless gallons down our drains only to end up at a sewage treatment plant or or shortening the lifespan of a septic system if you live in the country.
