Who specifies the number of drip emitters per linear foot in a drip irrigation system?

The manufacturer specifies the number of drip emitters per linear foot in a drip irrigation system. This is crucial because manufacturers design their products based on specific parameters, including the flow rates and spacing of the emitters, to ensure optimal performance and efficiency. By providing guidelines for the number of emitters, the manufacturer helps ensure that water is distributed evenly throughout the intended area while taking into account factors like the type of plant being irrigated, soil type, and system pressure. Proper adherence to these specifications allows for effective irrigation management, leading to healthier plants and more efficient water use.

While local health departments or engineers may have oversight regarding regulations and system design, they do not define the technical specifications for the products themselves. Installers rely on manufacturer specifications to set up the systems properly, following these recommendations to avoid issues such as under or over-watering.
