It always cracks me up to hear about water "usage". Nobody takes water. We just borrow it for a little while...
I had a salesman try to sell me on a very expensive washing machine that only used 2 oz of water for a full load. Ok, maybe a slight exaggeration... But my point was that my washer is on the same drain line as a toilet, far away from the "central" line, so I wanted one that used a lot of water to keep my line clean, just in case. He wasn't sure what to say about that.
I also told him that the quicker we used it, the quicker we returned it to the hydrological cycle, and the quicker it would come back to us. Circle of life kind of thing... I like playing with salesmen...
