Flushed with Pride!
Rich Hua stashed this in Just Plain Cool
The SinkPositive is a fixture with a basin and faucet. It replaces the lid of your toilet reservoir. When you flush, water streams through its faucet for handwashing and drains directly into the toilet reservoir, filling it up for the next flush.
The upshot: You use the water twice, first to wash your hands and then to fill the tank, and substantially reduce water use.
Despite a long-term shift to high-efficiency toilets, which use a quarter of the water a traditional toilet does, American toilets are clean-water guzzlers. Some 30 percent of household water consumption is used for flushing, according to the EPA. That amounts to about $5 billion worth of water down the tubes.
