Water Efficient Irrigation

From November 1st – March 31st, watering is limited to once a week, however, it is usually sufficient to water once every 15 – 20 days. Please adjust your irrigation controller or switch it to OFF to avoid potential pipe damage from freezes and fees associated with code violations. Turning your irrigation off can be completed at either the controller box located in the garage or the double check in the ground.

Water is the most important resource to sustain life and as the Earth's population grows, the need for water grows. Water is being used and wasted faster than it can be replenished.

Irrigation Efficiency

  • Lawn irrigation can be 40 to 60% of your water bill
  • Watering less than two times a week is usually sufficient
  • Brown grass does not mean dead grass
  • Frequent watering promotes shallow roots instead of deep long-lasting roots

What Can You Do?

  • Option 1: Set your controller properly to water your yard and adjust it with the seasons.
    • Check your current controller settings! The controller for your sprinkler system is in your garage on the wall.
    • Be sure it is set to the correct date and time
    • Program A is usually sufficient. Program B and program C can be switched to “OFF”. These two programs are for the same zones, they will just set the zones off a second time at a different time.
    • Choose your start time for each zone. Between 3 AM – 6 AM is best. If programs B & C are both off, be sure they have no start times. Why between 3 AM – 6 AM?
      • Less water loss from evaporation.
      • Least chance of attracting mosquitoes
      • Least chance of developing root rot
  • Set your time for each zone within your programs.
    • 💧 means it will run.
    • 🚫 means it will not run.
    • Between 3 – 7, minutes is usually sufficient. We suggest 3 minutes for the lawn and 4 minutes for the trees. If you have a soaker hose, refer to your manufacturer’s recommendations for a run-time.
    • Choose the days your system will run.  We suggest either once a week, like Wednesday, or twice a week, Monday, and Thursday. That way you have 2-3 days between each watering.
    • Twice a week is all that’s permitted between April 1st – October 31st. A maximum of once a week is permitted from November 1st – March 31st. Every 15-20 days is usually adequate during the winter.
  • Option 2: Shut your water off!
    • Manually turning your sprinklers on or hand watering gives you complete and total control of your landscape, lawn, and garden.
    • Allowing your plants to stress a little can be helpful in acclimating them to the weather and soil as it promotes deep root growth and ultimately reduces water run-off.
    • Saves the most water, meaning you spend less!


  • Plant native and drought-resistant plants that require less watering
  • Taller grass holds water more efficiently, don't cut more than one-third of the grasses length at one time
  • Buy or make a rain bucket to water your plants, AgriLife Extension has resources on the roof-water collection and rain barrels here.
