Water Conservation

There are many ways to conserve our natural resources and here is some information to specifically conserve water by using less water inside the home and planting xeric plants, etc.

    "Homeowner's Guide to Household Water Conservation"

Planting Xericscape (drought tolerant plants): 

    "Xeric Trees and Shrubs"

    "Xeric Perennial and Annual Flowers"

    "Xeric Ground Cover"

    "Ornamental Grasses"  

Also, protecting our water quality is just as important as conserving our precious water resource.

    "Homeowner's Guide to Protecting water Quality and the Environment"

Many lawns in the county are comprised of Bluegrass which takes more water than native grasses.  Blue grama is a Colorado native grass, and actually is Colorado's state grass.  This grass prefers a sandy loam soil and does very well without much water and needs to be mowed only once or twice depending on your preference. 

    "Blue grama Lawn from Seed"


Another way to conserve water would be to collect precipitation.  Please read below for the laws on Rooftop Precipitation Collection (Rainwater Harvesting).  

Rainwater Harvesting - Using harvested precipitation to conserve non-renewable ground water.  

 Senate Bill 09-080 was passed by the General assembly and signed by the Governor during the 2009 legislative session.  This bill allows certain property owners who rely on certain types of wells for their water supply, limited collection and use of precipitation, only if:

     1. The property on which the collection takes place is residential property; and

     2. The landowner uses a well, or is legally entitled to a well, for the water supply; and

     3. The well is permitted for domestic uses according to Section 37-92-602, C.R.S., or Section 37-90-105, C.R.S. (generally, this means the permit number will be five or six digits with no              "-F" suffix at the end); and

     4. There is no water supply available in the area from a municipality or water district; and

     5. The rainwater is collected only from the roof of a building that is used primarily as a residence; and

     6. The water is used only for those uses that are allowed by, and identified on, the well permit. 

If you do not meet, at a minimum, ALL of the above criteria, then the change in the law does not affect you and the current restrictions on collecting rainwater still apply.  This law was effective on July 1, 2009.

On June 8, 2013 the Douglas County Conservation District and the Rural Water Authority of Douglas County hosted a rainwater Harvesting Workshop in Castle Rock.  It was a wonderful way to learn about the laws and regulations in the state to collect rain and snowmelt for water conservation.    Sixty nine landowners and Five vendors listened to the four presentations on introduction to rain harvesting, laws and incentives, rainwater collection systems, and estimating runoff, etc.  The Colorado Division of Water Resources website has more information on SB 09-080 at   and the "Rooftop Precipitation Collection System" permit application (Form No. GWS-78) can be found online at
