Sprinkler Watering Tips

Learn how to use your sprinkler system in
the most effective way possible.

Some lawns require more or less water, depending upon the type of grass you have. Adding or removing one minute from the watering time will change the amount of water you use by 25 percent.

Use the cycle and soak method of watering. For each assigned day of watering, water your lawn 3 times a day, 4 minutes each watering. Schedule start times at least one hour apart.

When to Water

Water between midnight and sunrise from May to October to minimize water lost to evaporation. Water during the warmer part of the day during winter months to prevent water from freezing on your landscape.

Monitor how many minutes you can run your sprinkler system before water starts to run off the property. Stop the run cycle at that point. Allow the water to be fully absorbed before beginning the next cycle.

Other Tips:

  • Warm-season grasses, such as Bermuda, require about one-third less water.
  • If you have rotating sprinklers, water for 12 minutes each watering, rather than 4 minutes.
  • Don't water when it's windy or rainy.
  • Water your lawn on a separate schedule from your plants, trees and shrubs.
  • Test, adjust and repair your sprinkler heads and drip emitters weekly in the summer and monthly in the winter.
  • Always check your sprinkler system for malfunctions after mowing.
  • Modify spray patterns from sprinkler heads by re-adjusting for better direction or installing variable arc nozzles.
  • Replace your irrigation clock with a "smart" clock. Use an SNWA instant rebate coupon and save both water and money.
  • Visit one of the many desert demonstration gardens around the valley for landscape ideas.
  • Replace your water-thirsty grass with a water-smart landscape and you may qualify for a rebate.
