Jose Genovés designed the Natura, a toilet which adapts to male and female urination and defecation, lessening water usage by up to amazing sixty percent. The designer created it having in mind the fact that different kinds of waste require different amounts of water. For defecation, it increases the water consumption from 4.5l all the way to six to flush away stored toilet paper. For female urination, the urine is disposed through a separate environmentally-friendly siphon that uses just a 1/2l of water. For male urination, it provides a male urinal built-in into the design. The urinal disposes the urine with just a 1/2l of water, saving thirty percent of the water used by standard bathroom toilets for the very same purpose.
