design idea - watersaver 01

I've been thinking about a series of water saving devices.  It seems such a waste to not use water that is often just running down the plug hole whilst we brush our teeth, wash our faces or whilst showering.  The first simple idea is a hand basin thet fills a toilet cistern.  Once full the water simply overflows and goes down the drain. The cistern would self fill if there was more flushing than hand washing going on.
