Huh? Did Ihear you right? Toilets and showers use up most of the freshwater in a household. A single flush uses up to 3 gallons! With this new filtration system you can save 9 times as much water. The water goes into a chlorine filter and into a holding tank to be filtered again. This water is called gray-water. To me it sounds nasty to reuse your pee water for drinking water.
Soooooo cans toilets save water? YES!
