Water Recycling Showers
If you've ever felt guilty about using too much water in the shower, a water recycling shower setup may be the answer to your prayers. It's more than just a plain old showerhead: It's a showering system that will let you spend as much time as you want rinsing away your troubles without remorse.
With this system, you shower as you would normally, but when you get to the rinsing part, you activate a reservoir that recirculates the rinse water. You get more H2O at big water savings because you're using the rinse water a couple of times (or three or four) before it actually goes down the drain for good. Instead of settling for a stingy low-flow showerhead, you can have plenty of guilt-free water at your disposal. In development in water-conscious locales like Australia, water recycling showers may be the wave of the future.
