Irrigation Efficiency

The District promotes and encourages water conservation for both indoor and outdoor water use. Water use outdoors is generally twice the amount as water use indoors and only about 25% of that water makes its way back to local waterways. The large amount of water used for landscaping purposes, combined with the small amount that returns to streams, makes efficient and conservative water use extremely important. 

Efficient irrigation is very important in water conservation. Many of us are watering more than we need to or have inefficient systems. Here are a few ways to determine if your irrigation system is working efficiently: 

  • Request an irrigation evaluation. Individually Metered Residential accounts are eligible for a free irrigation system evaluation conducted by our certified staff
  • Water less and more efficiently. Adjust your irrigation settings, talk with your landscaper, and water just enough for the plants in your landscaping
  • Use a Smart Irrigation Controller. Replace your current irrigation controller with a Smart one that uses weather data, soil sensors, and rain gauges to automatically adjust irrigation based on plant water requirements. 
  • Upgrade and maintain your irrigation system. Look into upgrading your current system to be more efficient and effective. And yearly maintenance will ensure your system works properly and will help you avoid the cost of replacing it.

FOR NON-LAWN LANDSCAPING

Other types of landscaping usually require less water than lawn or non-native turf grass. In the below tables, vegetation in these areas require only 67% of the water used on lawns. Many types of vegetation will require little to no supplemental irrigation and these tables should be used as a maximum for irrigation. Consult with your landscaper, the CSU extension office, or other trusted resource to evaluate your landscaping needs.
