Quench Water-Recycling Shower - Guilt-Free Indulgence? : TreeHugger
Good link
Ive been thinking about this for years
Typically Im a 2 minute showerer like everyone else
But sometimes I just want to sit there and relax
The Quench Shower system, originating in Australia, involves a two-step process – the first being a regular shower where you soap up and rinse off, and the second in which you allow the shower basin to fill up and then let the Quench system recycle and reheat that water perpetually. So you can enjoy as long a shower as you like without using any more water.
