Harvesting rainwater is illegal in many places. I wonder why that is?
Most of those laws are really old and had to do with preventing upstream ranchers from stopping run-off from entering the shared stream\river system that downstream farmers\ranchers relied upon. They are way out of date for the most part and make no sense at all in urban areas.
If fact it should be code for residential to have rainwater tanks for use in toilet flushing and lawn care instead of using expensively purified drinking water for those purposes.
It would also save cities a lot of money on storm sewer system that have to handle all that unnatural water-shed coming off the paved cityscape without collection or enough greenery to absorb the rainfall. Instead that massive flow has to be handled by ever bigger storm sewer systems.
But we all know how hard it is to get rid of a law once it's on the books. Up until 1973 it was illegal to carry wire cutters in your vehicle in Texas. A leftover vestige of the range war days.
