WATER EFFICIENT TOILET
design for sustainability
Company: TU Delft + European Union.
Project: Project developed for my Master´s Graduation in the "Design for Sustainability" department of TU Delft. // Guided by Ruud van Heur and Daphne Geelen (TU Delft).
The Living Green project is an European cooperation with the objective to demonstrate technologies, methods and strategies for sustainable renovation. I focused my thesis on making the toilet more water efficient, since water is becoming a scarce resource while a standard toilet consumes 15 times more drinking water per day than a human being does. The result is Natura.
HOW DOES IT WORK?:
Each type of human waste requires different amount of water to be flushed away. Natura makes difference between toilet’s performances and discharges the right amount of water for each one of them:
A.- Natura provides a male urinal integrated into the toilet design. The urinal will dispose the urine with only half a liter of water, saving 30% of the water used by conventional toilets for the same purpose.
B + C.- Natura also has a separating bowl that disposes liquid and solid waste independently. The bowl has 2 drainages, a standard one using 6 liters of water to dispose the solid feces, and an extra mini drain that only uses half a liter to flush the urine.
