Hm, how about reversing "toilet-to-tap" into "tap-to-toilet"? I guess its too complicated to flush toilet with water from shower or dishes.

  Those "Tiny" houses do it already. We have the technology.

    It was pretty common in soviet Czechoslovakia. Another "high tech" communist trick is to put flush reservoir to ceiling, higher pressure requires about 30% less water.

  When I visited Japan, I saw many toilets that had a little faucet/sink built into the toilet lid, so you could wash your hands with it before it was used to fill the tank. However, I'm not sure how practical that kind of thing would be to do at house-scale. You'd need to have extra set of plumbing, plus storage tanks for the greywater (and probably pumps to get it there), among other extra things.
