CANYONS SCHOOL DISTRICT IRRIGATION PROCEDURES

• Canyons School District has set up their irrigation controllers to water based on the evapotranspiration rate (ETo). ETo is the combined total water that is evaporated from the plant leaves and soil surface and the water that is transpired, or moved through, the plant.
  • 1. Due to the sizable acreage at each facility, nightly irrigation occurs during the Governor’s water window. If the District did not water nightly, there would not be enough time to replenish the water lost through ET. Play fields and grounds would become hard and unsafe for student activities and  sporting events.
• Canyons School District irrigates to a matched precipitation rate. Precipitation rate is the rate at which the irrigation water reaches the ground surface, usually measured in inches per hour. Matched precipitation rate means that each head is emitting water at the same rate.
• Canyons School District utilizes Calsense smart controllers to irrigate to the ETo. Where there are rain cans the controllers shut down irrigation if .1″ of rain falls. When there is not a rain can, the controller applies the rain amount to the next irrigation cycle and may reduce the following days irrigation cycle.
• Grounds are inspected weekly to evaluate turf and plants. Adjustments are made if changes are required due to over or under watering.
