The only answer I can give you on that is:
If you are a land owner and want collect rain water than do that. If someone wants to prevent you from doing it go to court and search for support.
I don't care for cases I never will have the chance to be an active part of a support group or becoming physically present.
I care exactly for those cases, environments I can get my foot in and be effective in what I think is ethical acceptable.
Pick your theme. Spare me general themes from which I cannot recognize who you are and what you actually do.
