In the state of Colorado, those with water rights already have dibs on the rain that falls on your property, unless you have your own well (and even that has limits).
If you use municipal water, you can’t use a rain barrel or cistern to collect rain that would otherwise run off or disappear into areas where it’s not needed. Having a private well may grant you a permit to use rainwater for irrigation, but not if the well is already restricted for household use.
(There is currently a Colorado pilot program to test rainwater catchment systems in new housing developments, but that won’t do anything for most of us today.)
Still, you don’t have to be resigned to the status quo.
Yes, there are legal ways to keep more and “harvest the rain” for yourself, as the title of a new book proposes. Not only is it in the best interests of a community to sustain itself on local water, but our waterways need help to keep soil and contaminants from flowing into them after rain slides off our roofs.
So says author Nate Downey, owner of a Santa Fe landscape design firm who writes on permaculture for the Santa Fe New Mexican newspaper. His Harvest the Rain is published by Sunstone Press and available on his website (www.harvesttherain.com/index.html), as well as the usual book outlets.
“Conservation only puts off the problem in the sense that throughout the Southwest and much of the world our water resources are depleted,” says Downey. “We have to do more than conserve.”
For example, the Ogallala Aquifer, which extends from South Dakota to Texas — the High Plains’ lifeblood for all uses — is losing out to demand instead of seeing sustainable restoration from rain and snowmelt.
And global climate change is making reliable supplies of clean water that much more problematic.
Fortunately, current and future water shortages can be alleviated with better utilization and technology — if we demand it and act on it.
All water — even the kind considered “gray” or even “black” by purity standards — can be cleaned to the point of being safe to drink. However, current technology is not yet cost-effective enough for this to become widespread practice, says Downey. In the meantime, there’s still valuable usage left in “wastewater” for irrigation and other needs.

And for a more hands-on kind of how-to, there are local classes to check out.
Transition Colorado and Real Earth Design! are offering weekend workshops April 16-17. The cost is $65 each day.
