Matched precipitation rate refers to sprinklers delivering what?

• A. The same rate across all sprinklers in the area
• B. Different rates for each sprinkler
• C. Higher rate at edges
• D. Lower rate at center

Answer: (A)

Matched precipitation rate means every sprinkler in the same zone delivers water at the same application rate, typically measured in inches per hour. This uniform rate ensures the entire area receives about the same amount of water, so no spots are overwatered or underwatered. Even if you use different sprinkler head types within a zone, you adjust run times or design so the overall rate is consistent across the area. If the rate varied from head to head, some areas would get more water than others, creating uneven moisture and problems with plant health and efficiency. The goal is a uniform distribution, not higher water at edges or lower water at the center.
