Set Up a Base Watering Schedule

Summer runtimes are defined as having a 100% watering index value. Why? Because summer is the peak season for plant water demand. You can use your existing summer schedule that you may have already set up.

Alternatively, you can use the watering calculator to figure out the runtime for each zone (also called a valve or station) in your sprinkler system. Use our watering calculator to set up a custom watering schedule for your yard based on plant type, sprinkler type, and soil type (SMWD typically has clay loam soil). You will be given a chart of watering times as shown below:

Grass | Clay Loam | Sprinkler

Month January February March
May June July August September October November December
Watering Days per Week
1 1 1 3 3 3 3 3 3 3 1 1
Minutes per Cycle
8 5 8 7 8 8 5 8 7 5 5 8
Cycles per Day
1 2 2 1 1 1 2 1 1 1 2 1

Use the July runtimes for your 100% watering index setting. For example, using the Grass chart above, July says to water 3 days per week, with 2 watering cycles that water for 5 minutes in duration. You can schedule runtimes for all your sprinkler valves based on plant and sprinkler type associated with each valve.
