The dual system is one of Colorado’s largest, and it includes separate irrigation and potable water systems that provide water for about 33,000 households and businesses. The irrigation system includes its own set of alluvial wells and completely separate infrastructure from the potable drinking water supply system. Each system includes separate pipelines, pump stations, and reservoirs used to deliver the different supplies. The dual system allows the District to maximize their water rights and ultimately supply more homes efficiently.
Mandatory Irrigation Schedule
Irrigation shall not occur between the hours of 10:00 am and 6:00 pm.

Using the SystemIt is important to understand that the entire separate irrigation system is a non-potable system, not for drinking. Customers served by the District's dual irrigation system will need to maintain their system's components including the Pressure Vacuum Breaker (PVB) assembly installed on the irrigation system. A link to the Operation and Maintenance Manual showing the PVB assembly is provided here.
Spring Start-up Instructions
The District begins charging the irrigation water transmission line the week of April 15th. Once the lines are charged, property owners will be able to access irrigation water to their separate irrigation system by completing the following instructions:
Follow the Startup Instructions to turn your system on, and be sure to turn it off each winter.
Check for broken sprinkler heads and irrigation system pipes that are broken and causing puddling in the lawn. Turn your system off at the “stop and waste” valve until the leaks are repaired.
Adjust sprinklers for head-to-head coverage, and make sure they are spraying on landscaped areas, not streets or sidewalks.
Adjust your time clock to irrigate your lawn appropriately for each zone, please follow the mandatory watering schedule.
If you hire a professional to provide irrigation start-up and shut-down services, be sure they are knowledgeable about the separate irrigation system and familiar with the District’s Rules and Regulations.
