What is the minimum pressure requirement for distribution lines in a drip irrigation system?

The minimum pressure requirement for distribution lines in a drip irrigation system is fundamental to ensuring the effective operation of the system. A pressure of less than 10 psi is typically sufficient for drip irrigation, as it allows for the proper functioning of emitters and the even distribution of water without creating excessive force that could lead to the unwanted splashing or runoff. This low pressure is crucial since it helps maintain a slow, steady flow of water, which is ideal for deep penetration into the soil and reduces the risk of erosion.

Drip irrigation systems are designed to operate under low pressure, which is one of the key aspects that differentiates them from other irrigation methods. Higher pressure levels are not only unnecessary but can also lead to inefficiencies in the system. Thus, maintaining a pressure below 10 psi is both a practical and effective approach for the operation of drip irrigation systems.
