Landscape Irrigation Design Manual
Introduction
Properly designed, installed, maintained and managed landscape irrigation systems greatly reduce the volume of irrigation water that is wasted every year. In some water short areas, we have seen the beginnings of planned water conservation efforts. In time, these could become the basis for a coordinated national policy toward water conservation. Today many municipalities require home or business owners to submit irrigation designs for approval prior to construction.
This manual is part of the effort to promote properly designed landscape irrigation systems. It is our goal to present the material as simply as possible while explaining some theory behind the process. Understanding the basic hydraulics material in the first section of the manual is very important, especially to new students of irrigation design. Even intermediate level design students may find it helpful to “brush up” on hydraulics before going on to further studies. With that said, please turn the page to discover some facts about the nature of water.
