Information on new rainwater collection law in CO

There is a new law coming into effect on July 1, 2009 which regulates the use of rain barrels to collect precipitation running off roofs. There has been some confusion as how exactly the water can be used. The Colorado Division of Water Resources has put together a pdf document outlining the new rules.
In short: Here are the criteria, all of which must be met, for using rainwater:
1. The property on which the collection takes place is residential property, and
2. The landowner uses a well, or is legally entitled to a well, for the water supply, and
3. The well is permitted for domestic uses according to Section 37-92-602, C.R.S., (generally, this means the permit number will be five or six digits with no “-F” suffix at the end), and
4. There is no water supply available in the area from a municipality or water district, and
5. The rainwater is collected only from the roof, and
6. The water is used only for those uses that are allowed by, and identified on, the well permit.
Check the full pdf for all the details!

Basically, if your well isn't permitted for use in watering a greenhouse or hoophouse-you can't use the collected rainwater for this purpose. And you will need to submit an application for rainwater collection! If you use municipal water, then you're out of luck too, as this only applies to residential properties serviced exclusively by a well. Please contact the Colorado Division of Water Resources for all the nitty-gritty details!
