This is a pretty cool idea, and it makes sense. I wonder how hard it would be to DIY?

Closed-loop futuristic recycled water shower reduces bills by $1,300 (Video)

In a standard shower, a mere 10 minutes can use up to 150 litres (40 gallons) of water. Building upon the idea of designs used for space travel, where astronauts will reuse the same water over and over again, OrbSys is a closed-loop system that cuts down on water consumption by purifying shower water that drains at the bottom to drinking standards, and is cycled up to the shower head be used again.

The system uses only about 5 litres (1.3 gallons) of water for a 10-minute shower, or 90 percent less water and 80 percent less energy, potentially translating to over $1,300 worth of savings each year.
