Irrigation Installation Best Practices

  1. Zone/Station Sizing: When installing an irrigation system it is important that the Gallons Per Minute used by each zone does not exceed the Gallons Per Minute provided by the water source. When a Zone/Station is not properly sized the heads will not operate at optimal performance. This will result in the spray patterns of the heads not properly covering the landscape assigned to that Zone/Station.
    NOTE: Pressure regulated heads along with properly sized Zone/Station will increase the efficiency of your sprinkler system by up to 25%.
  2. Matched Precipitation: Head to Head coverage with properly sized nozzles is recommended for proper coverage. In high wind scenarios the coverage should overlap by as much as 10%. When sprinkler placement is stretched beyond the recommended settings the result is dry spots. Frequently the owner will increase watering to solve this problem. This results in wasted water and possible disease in other spot being overwatered.
    NOTE:  A system with improper head placement cannot be properly managed by a Smart controller. Smart Controllers can save up to 40% on your water usage.
  3. Zone Breaks: Besides the restrictions of Gallons Per Minute and PSI, Micro-Climates must be considered. What is a Micro-Climate? EXAMPLE: A large front yard that is 1/2 full sun and 1/2 shade. The zones should be separated to reflect this as they will each need to be watered differently, OR A side yard that runs along the driveway and between your house and the neighbor’s house. You might have enough Gallons Per Minute and PSI, but along the driveway is full sun and between the houses is shade.
    NOTE:  A system not zoned properly cannot be properly managed by a Smart Controller. Smart Controllers can save up to 40% on your water usage.
  4. Topographical: When installing a sprinkler system features such as the grade of the property, Soil make up, turf type, landscape material, must all be considered as factors to the type of zone, sprinkler head, drip set up, and more. these factors will impact the proper function of your sprinkler system. Soils absorb water differently, sloping causes runoff, trees and large shrubs will block sprays, different types of vegetation needs different amounts of water.
    NOTE: A Smart controller will make these and more calculations for you daily resulting in up to a 40% water savings.
