Wayne,
I will see what I can do about letting the authorities know that you need a water meter.
Here they have a small white car that drives around every day all Summer looking to see if anyone has water going in their yards or is washing a car. They stopped here once a year or so ago when I was washing my car, but once they saw how I do it they said that was ok. I never use a hose or soap. Just get a bucket with about a gallon of water and an old T Shirt and wipe it off then dry it with an absorber. Once I got the wet paint on it, that is all I have ever used to wash it.
