Basically, what are jurisdictional issues.
Here’s the skinny. My city is very anal about enforcement. If you are clearing brush and leave it out front overnight, you get a citation. If your car is on the front lawn, you get a citation.
Now I know that the federal government outlaws using “grey water” viz sink, dishwasher, and clotheswasher runoff. Assuming my city does not have a law against it, if I get caught using my grey water to water my plants, what can the city do?
