In irrigation terms, what does a higher PSI indicate?

A higher PSI, or pounds per square inch, indicates greater water pressure in an irrigation system. This increased pressure is essential for various functions within the system, including the ability to deliver water over longer distances and to operate more than one sprinkler or emitter simultaneously.

When pressure is increased, the velocity of water moving through the pipes also increases, which can enhance the distribution of water across the landscape being irrigated. It allows for a more effective and uniform coverage, which is essential for maintaining healthy plants and efficiently using water resources.

While higher pressure can contribute to improved efficiency in some cases, it is not automatically indicative of system efficiency or reduced water usage; it primarily relates to the capability of the system to deliver water under such pressure. Thus, understanding the relationship between pressure and irrigation performance is crucial for effective system management.
