What is the desired relationship between sprinkler heads in a well-designed system?

The desired relationship between sprinkler heads in a well-designed irrigation system is that they should overlap to achieve full coverage. This overlapping arrangement is essential because it ensures that there are no dry spots in the irrigated area, providing uniform water distribution across the landscape. When sprinkler heads overlap properly, it helps to compensate for variations in water pressure, wind, and evaporation, all of which can affect irrigation effectiveness. By creating a network of overlapping spray patterns, the irrigation system can work more efficiently and effectively, promoting healthy plant growth and conserving water resources.

Other arrangements, like maintaining specific distances apart, may lead to gaps in coverage, while a circular pattern may not be the most efficient layout for all landscaping configurations.
