Sinkpositive

A company called Environmental Designworks has created a unique bathroom sink that's made to sit on your toilet's water tank and interface with its existing plumbing.The sink of course only uses the fresh water that is also used to refill the toilet after you flush. The water basically takes a slight detour through the Sinkpositive first and as a result it eliminates the need for additional water usage when you wash your hands afterwards. The other benefit is that since the Sinkpositive only runs while the toilet is refilling there are no extra knobs or handles to touch once your hands are clean.
