In Utah, 65% of our home water use goes on the lawn- and we know for a fact that about half of that water is all waste! Lawns in Utah can take less water (and look better than ever) if you follow this watering guide. The Utah EvapoTranspiration Network (UET-Net) is an effort by the Utah Division of Water Resources to help educate Utahns about the proper way to water their lawns.
There are a few basic concepts to understand about lawn watering. Firstly, stop thinking of it as "watering your lawn", and start thinking of it as "filling the soil reservoir". We can liken the soil reservoir to a gas tank. Beginning with a full soil reservoir, we "drive" the lawn (through weather) and thus expend "fuel" (water). After 1/2-inch of your "fuel" is depleted, then it is time to top-off the tank!
But what is 1/2-inch of water? We usually measure our water use in gallons or cubic feet, so learning about "inches" can be somewhat confusing. In order to explain this more fully, please visit our Residential Lawn Watering Guide section to learn how to make your sprinkler system as efficient as possible, and how to tell how long you have to run your system to apply 1/2-inch of water! Each sprinkler system is different, so this step is highly recommended.
After learning how to apply 1/2-inch of water, you can check UET-Net once a week to find out how many times this week you need to apply 1/2-inch to your lawn in order to "top-off" the soil reservoir! Remember, this site will tell you how much water your lawn used in the past week, so it's important to check this site only once a week. Try picking a day and sticking with it!
So pick the station closest to your home, and enjoy!
