“Irrigation Performance” is often used to describe the combination of Uniformity and Efficiency
Irrigation performance is affected by how well the irrigation system is designed, installed, maintained and managed. Irrigation friendly planting areas (size, shape and slope) that maximize irrigation performance will improve plant health and lower plant water needs.
Sprinkler systems are inefficient; rarely are they maintained to operate above 50% Distribution Uniformity (DU) for spray sprinklers and 60% DU for rotating sprinklers. Fixed arc spray sprinkler nozzles have better DU than adjustable arc nozzles. Strive to use only fixed arc nozzles for spray sprinklers on your property.
