Think Opposite: Foot Pedal Water Faucet Controls
This makes so much sense, I don't know why more people aren't using these. Usually found in hospitals or industrial kitchens, foot pedal water facets are not only more hygienic, but also have the potential to reduce wasted water use by 50%.
At a sink, you control the flow of a faucet with a pedal much like the accelerator in a car. It’s easier to turn off the faucet when you are brushing your teeth, shaving, or doing the dishes. In a four-person household, the use of pedal controllers in the kitchen alone can save up to 7500 gallons of water annually, as well as conserve the energy needed to heat those gallons.
