I was lucky enough to receive a tour of the Good Hotel (“intended to be the first hotel with a conscience” opening in San Francisco, which I may write more about later). It was there that I first encountered the SinkPositive, a remarakble water saving bathroom fixture – a sink that is placed on top of the toilet tank and allows consumers to use toilet flushing water twice: once to wash their hands and again to flush the toilet. The fixture goes for $109 – $119 plus S&H and replaces your traditional toilet’s tank lid. After every flush, the water that comes from the water supply line comes out of a faucet at the top of the toilet allowing you to wash your hands as it refills the toilet bowl. It looks sort of link a dentist’s sink. The SinkPositive is not meant to replace the bathroom sink, but will eliminate the need to use more water for handwashing post-bathroom visits. Basically SinkPositive creates a greywater system that is easy to install and use, inexpensive, and allows a household to operate without interruption.
