Seminar Description:
A successful irrigation system begins with understanding the available water supply. In this seminar, participants will learn how to evaluate water availability by working through a practical design capacity worksheet. The session will cover how to calculate system design capacity in gallons per minute (GPM), determine the available pressure at the point of connection (POC), and estimate the pressure at the worst point in the irrigation system.
By the end of the seminar, participants will have a repeatable process for determining whether an available water source can support their irrigation design and will be able to apply these methods to future irrigation projects.
Learning Objectives:
1. The importance of knowing how much water you have available.
2. Selecting the proper emission devise based on GPM and pressure.
3. Properly sizing irrigation components on a Landscape project
