Colorado passes law to allow rainwater harvesting
via Boing Boing by Mark Frauenfelder on 6/29/09
In March I pointed to an LA Times story about people in Colorado who were breaking the law by collecting and saving rainwater from their roofs to water their gardens during dry spells.
Holstrom's violation is the fancifully painted 55-gallon buckets underneath the gutters of her farmhouse on a mesa 15 miles from the resort town of Telluride. The barrels catch rain and snowmelt, which Holstrom uses to irrigate the small vegetable garden she and her husband maintain.
But according to the state of Colorado, the rain that falls on Holstrom's property is not hers to keep. It should be allowed to fall to the ground and flow unimpeded into surrounding creeks and streams, the law states, to become the property of farmers, ranchers, developers and water agencies that have bought the rights to those waterways.
But the NY Times reports that Colorado passed a couple of laws to make this practice legal.
A study in 2007 proved crucial to convincing Colorado lawmakers that rain catching would not rob water owners of their rights. It found that in an average year, 97 percent of the precipitation that fell in Douglas County, near Denver, never got anywhere near a stream. The water evaporated or was used by plants.
But the deeper questions about rain are what really gnawed at rain harvesters like Todd S. Anderson, a small-scale farmer just east of Durango. Mr. Anderson said catching rain was not just thrifty — he is so water conscious that he has not washed his truck in five years — but also morally correct because it used water that would otherwise be pumped from the ground.
