The new mantra of "let it mellow" for all urine deposits should be adhered. That's right do not flush. Better yet, shut the water valve off on your toilet and fill the tank with dirty bath or sink water.

Come to think of it, why do toilets use "fresh" water anyways? Wouldn't it make sense to have your toilet fill with your drain water? Doesn't this seem like a complete waste of resources?
This guy has got the right idea.
