I would like to know how many "X" gallons of waste water it takes to make "X" gallons of product water?!? After that, consider some of the other wasteful products in your home such as your wahing machine. We have young children, so we bought a Fisher/Pykel (front load type) washing machine which touts that it uses 14 gallons of water compared to your typical top load wahing machines that use 44 gallons of water. I dump my waste water down the drain. I have often thought of a storage bin right outside which i would use for rlowers and such. For now, I'll let the rain take care of the flowers.
