A tonne of water is wasted every day down the john because of one standard flush setting, but the Natura Toilet boasts the ability to deal with three different types of relief and the consequent reduction of water consumption by about 60%.
One way that it does this is by having a pull-down urinal for male urination that involves the same action as lifting and closing the toilet seat. According to Jose Genovés' design, the flue uses a mere half liter to wash it away. When a woman sits down to pee, the toilet paper she uses will be flushed into a secondary chamber with half a liter as well. When someone finally empties his or her bowels into the bowl, between 4.5L and 6L of water are used up to make sure the pipes of the Natura Toilet are rinsed clean.
