Urinating in the shower saves water and paper waste, also reduces point-source pollution (“the solution to pollution is dilution”, allowing for natural environmental processes to break it down.  I’m not sure I could do it though.

Kids at East Anglia University in England are promoting this – it would save swimmingpoolsfull of water each year.

Where I live now we have a well and septic system that basically puts the water right back into the ground.   The well uses quite a bit of electricity to pull the water up 100s of feet from the ground, this could be a money saver as well as a time saver.
