Here’s another interesting toilet upgrade that can help you save water in the long run.  The Sink Positive is a toilet tank lid replacement that could help you use less water and encourage healthy hand washing.  The lid replacement includes a small sink that turns on after you flush the toilet.  As the water runs out of the tap and down the drain, it refills your toilet bowl.  It’s a simple idea that could be effective and essentially refills your toilet using grey water.  Apparently the design has been popular in Japan for some time now but is just now catching on in the U.S.

I personally think the sink would make more sense if you could turn it on whenever you wanted but nonetheless it’s a smart idea.  To find out more about the Sink Positive, visit their website.
