What does GPM stand for in irrigation?

GPM stands for Gallons Per Minute, a critical measurement in irrigation. This unit quantifies the flow rate of water being delivered through an irrigation system, which is essential for determining how much water is available to irrigate plants effectively over a specified time. Understanding GPM allows irrigators to assess whether the system can meet the water demands of the landscape being serviced and helps in planning appropriate watering schedules. For instance, if a certain area requires a specific amount of water per week, knowing the system's flow rate in GPM enables the irrigator to calculate how long to run the system to meet that requirement.

Other options such as Gallons Per Month, Gallons Per Measurement, and Gallons Per Manifold do not accurately represent how irrigation systems are typically assessed for their efficiency and effectiveness. Gallons Per Month would not provide the timely data needed for irrigation planning. Gallons Per Measurement isn’t a recognized term in water delivery contexts. Gallons Per Manifold could imply a specific component of a system but does not convey the overall flow rate critical for effective irrigation management.
