Use 10 times less water per day

As we become increasingly urbanized, it will be difficult to continue consuming and using the same mechanisms without devastating effects on the environment. That's why a husband-and-wife team, consisting of an engineer and a designer, set out to create an eco-responsible apartment, an urban biosphere, all in low-tech, with accessible tools and approaches.

Various choices forced them to think differently about their approach. The question of water is essential, since not only is drinking water used for everything in Western countries, but this over-consumption leads to the risk of water shortages.

For their home, they came up with solutions to cut their daily water consumption by a factor of 10. They developed a 2-liter water heater that requires no electricity. The shower becomes a mister, a method already used by NASA, which consumes much less water. The wastewater from washing is then used to feed a crop of plants that don't need 100% clear water to survive. This avoids wastage.

To wash the clothes, they use a washer that uses minimal water and is powered by a rowing machine. So they can get into shape without using electricity. Finally, their toilet is designed to be dry and divided into two parts. Urine is collected on one side and used to feed plants with nitrogen, and on the other, faecal matter falls into an environment of larvae that feed on it and produce fertilizer.
