In the developed world we mostly take it for granted that if we need water for something we can get it by simply turning a faucet. But that's not true for everyone, and it's completely possible that in the future it won't be true for anyone.
Washit addresses the issue of water conservation head-on, with a device that recycles shower water and uses it to clean clothing. The innovative product was created by four industrial design students, Ahmet Burak Aktas, Adem Onalan, Salih Berk Ilhan and Burak Soylemez. Their device is a still being developed, but the device has already won a 2012 iF concept award.
The sleek white shower pod works using a filtration system that takes in used shower water and filters it using a grey water system before cleaning your clothing with the recycled water. The Washit filters water cheaply and effectively, removing bacteria, oil, soap and hair.
Washit's creators believe their device could be used in private homes as well as in public in settings including gyms, festivals and even airports. Imagine stepping into the shower fully clothed during a layover in airport, removing your clothes and placing them directly into the washing machine. When you're done showering you clothes will be clean and read to wear.
More info on how it works, from Washit:
Washit has a closed plumbing system with 2 water pumps, 3 filters (carbon, organic and chemical) , 1 heater and a water storage unit. While user is having a shower, Washit gather graywater from shower cabinet to the water storage via filters. So all the water in storage is cleaned and ready to be used again either for showering and washing clothes. After the shower, user can take back his washed clothes or leave them there for Washit to dry. Washit refills itself from water main in case of water loss.
