I didn't even think it was illegal in any state to collect rain water that comes from the sky.
I just looked up about being illegal to harvest rainwater and it's stupid that there are even laws on this.
Rain water is water given to us and is not owned by anyone.
That's a violation of your human rights that you can't collect and use rain water. That's government controlling us.
I'm not sure about the State of Kansas but I'd say go ahead and put out some rain water barrels and if they say you're illegally harvesting rain water then I'd take it to court and fight it out.
