How does my soil type impact my watering times?

If your yard is comprised primarily of sandy soil, water will drain rapidly through the root zone. In a yard containing clay soil, water will run off quickly. In both cases, if water is put down on your lawn for an extended period of time, turf grass will be unable to use all of the water. We recommend using the “cycle and soak” method in which water is put down in small amounts over a period of time. For example if you need to water for 15 minutes, it is better to put down the water in three 5-minute intervals with a 45 to 60 minute break between each cycle. This will allow the water to be effectively absorbed by the soil around the root zone.

Sample Weekly Watering Minutes Calculation

Suppose you have pop-up heads that have a precipitation rate* of 1.5” per hour and the “Amount to Water” this week is 1.25”. According to the table, you need to run your automatic sprinklers for 50 minutes over the entire week. If we are recommending you water 2 days a week, then you will need to set your zones to water for a total of 25 minutes each day you water.

* To figure out your precipitation rate either perform a catch-can test on your system, sign up for a free irrigation assessment from Aurora Water Conservation by contacting 303.739.7195, or use this table to determine average precipitation rates for automatic sprinkler system types.

Advanced Assessments

To get an even more accurate assessment of your watering needs incorporating soil moisture content and/or distribution uniformity you can use the Designated Watering Day Schedule (more advanced) or the Soil Moisture Bucket Irrigation Schedule (most advanced) worksheets.
