Graywater is a portion of the water used in a residential, commercial, or industrial building that may be collected after the first use and put to a second beneficial use. Though recent changes to Colorado statues and regulations provide a framework for the use of graywater, graywater use remains subject to compliance with local regulation and Colorado’s water rights system. Jurisdictions at the city, city and county, or county level must create a graywater control program and adopt an ordinance or resolution to allow graywater use prior to graywater use in the jurisdiction. Contact your local government office to find out if your jurisdiction has a graywater program.
Graywater use is subject to compliance with Colorado’s water rights system, including well permit conditions and water supplier restrictions. Please see DWR’s 2011 Administrative Position for Graywater Reuse or contact DWR to learn more about the interactions between graywater use and Colorado’s water rights system.
