Gray is also Green

Thanks to a dear friend of mine, I was just introduced to this brilliant gray-water system, which exemplifies how simple engineering and a little bit of design sense can make an environmentally friendly, aesthetically pleasing, functional, every day piece of equipment. It's taken us enough time, but finally we have developed a modern way to reuse waste water from washing our hands to feed the basins of our toilet bowls. This sink and toilet combo by Roca seems to do the trick! Scoot over dual flush toilets, you've got some green-market competition...
