Chris Hadfield Explains Water Recycling on the International Space Station

The water recovery system on the International Space Station was instrumental in allowing larger crews to board the craft, thanks to the reduced need to be resupplied from Earth. Water is a precious resource on board the ISS, as Canadian astronaut Chris Hadfield showed while he was commander. In this video, he demonstrated how 93% of the water used on board gets reclaimed.
