Rainwater Collection laws in Colorado
Colorado has historically regulated water rights very strictly due to its arid climate. However, in recent years, the state has relaxed some regulations regarding rainwater harvesting for residential use. The current framework allows homeowners to collect a specific volume of rainwater, provided it is used for approved purposes such as outdoor irrigation on the property where it was collected. This limited permission aims to balance water conservation efforts with established water rights. Any collection beyond the specified limits or for unapproved uses may be subject to legal consequences. The regulatory approach emphasizes that collected rainwater is not considered a new water right but rather fall under existing water management principles. Therefore, while collection is permitted under certain conditions, it is not an open-ended right. The intent is to encourage water conservation while preventing impacts on downstream water users who hold established water rights. Specific guidelines are in place regarding the number of rain barrels and the total collection capacity allowed per household.
