I use ONR, so when I wash my car I use MAYBE a gallon of water at most, and barely anything drips off the car. I wipe clean and then dry, and I use a separate bucket for the dirty water that I just dump down the drain in my garage, which feeds into the home drainage and not the run off drains. So it's no different than if I dumped it down the toilet.
