Rainwater Collection#
In 2016, Gov. John Hickenlooper signed legislation allowing rainwater collection in Colorado.
Rainwater collection, or rainwater “harvesting,” is the process of collecting, storing and putting rainwater runoff to use.
This change in legislature came after a study by Colorado Stormwater Center showed that rainwater collection does not take water away from the supply available to agriculture and other water-rights holders. The study also showed that nearly all of the water collected would be absorbed in the ground by the downspout or in the garden.
