I found this bit of an article by Korey King on the Urban Renewal Think Tank site which has a lot of good forums on a lot of good ideas and news on progress.http://urbanevolution.org
any system of any size in use on your property (however, the materials themselves aren't illegal -- it's just against the law when it rains). This is what's commonly known as Batshit Crazy Capitalism -- in this case private corporations or municipalities lay claim to the rain itself, make it illegal for you to use it, and/or tax you to build more stormwater infrastructure so they may resell the rain.
some areas may provide Permits For You To Use Rainwater (for a fee). Check with your local rainwater racketeers for details.

Much rainwater collection is already illegal or at least highly regulated in WA state. And in most areas with agriculture I would bet there are similar laws or some sort of legal protection for farmers to buy access to water for irrigation. But our state gov’t has said they will not prosecute home owners who are simply installing rain barrels for personal use, they are more interested in regulating commercial use.
"Colorado Water Law requires that precipitation fall to the ground, run off and into the river of the watershed where it fell. Because rights to water are legally allocated in this state, an individual may not capture and use water to which he/she does not have a right."
As well as some good ideas for things to ask local (Especially Colorado) legislators. These were submitted as quotes which is a great attribute of the Urban Renewal Think Tank [http://urbanevolution.org]
"If I collect rainwater in a barrel that means I’d be stealing from the state. But what about my lawn and flower beds? They absorb some of the water before it runs off into the rain gutter, so is my lawn breaking the law? Do I need to put a big tarp over my house and direct all the rainwater into the gutter for fear of prosecution?"
"If the rain belongs to the State, it’s effectively the property of the State. In that case is the State liable for damages caused by their property such as water damage and flooding? If they’re not liable for damages caused by their property, is it right that they hold you liable for damages caused by your property?"And of course, i had to join this think tank and forum and put my two cents in:
On the Good News side of things, some states are moving toward a more sane and progressive approach to rainwater harvesting:
