Water Conservation During Drought

May contain: paper and text

In residential areas, the greatest source of water consumption (after that of indoor water use) is your lawn. Nearly 50% of the water consumed for residential use is applied outdoors. Save water by:

  • Not using sprinklers when it is really windy.
  • Not watering when a heavy rain is forecasted.
  • Watering your lawn every third day.
  • Watering during the cool time of the day (6pm to 10am).
  • Determining the proper irrigation amount and duration needed by your vegetation.
  • Adjusting your automatic sprinkler settings to meet your lawn’s needs.
  • Installing drip or micro irrigation.
  • Practicing Xeriscaping.
  • Engage in Routine Water Conservation Practices

Xeriscaping

Xeriscaping (pronounced “Zer-i-scaping”) is landscaping adapted to semi-arid and arid climates. Natural precipitation is limited in our area. Compared to the annual precipitation of 30” in New England and 70” in Mississippi, you can understand why in Colorado (with an average annual precipitation of 17”) we can’t grow the same Kentucky Bluegrass lawns seen in the East without excessive irrigation. When installed correctly, xeriscaping can save up to 30% on a home’s water bill.

Xeriscaping incorporates these basic principles:
  • Limit your turf area. Consider planting grasses known for their drought tolerance and ability to survive with minimal fertilizer. Avoid fine and tall fescue grasses.
  • Maintain taller grasses, and leave the clippings on the lawn to recycle their nutrients.
  • Choose native, drought-tolerant plant species. 
  • Choose an efficient irrigation system. Turf areas do best when watered with sprinklers, but drip irrigation is sufficient for shrubs. Conduct a water audit on your irrigation system.
  • Use mulches liberally. Mulch helps maintain soil temperatures, retain water, and reduce weed growth.
