If you took it to a quarter car wash here they would shut down the hose and have the environmental people here before you knew it. The same for spraying under the body in winter.
When you mention recycling the water think about all that old salty water that came off someone else's car in the winter and is now being sprayed on your car's body.
I once presure washed my rabbit cage and took it out of the trunk. The TV camera could not pick up what I was spraying behind my car and the operator was there in a heart beat.
