Irrigation plans
The most sustainable irrigation approach of all is a water-harvesting system. You don't really need to draw plans for that part of the project. However, you do need to understand how it all works and how to create a system on your property. I cover that thoroughly in Chapter 8.
If you decide to install a permanent irrigation system, there are a couple of ways to determine how it all goes together. For most small systems, an understanding of basic irrigation design principles and a little time out in the yard can be adequate. If your system is large or complex, or if you'll be hiring someone to install it, you may want to draw a detailed irrigation plan or hire a pro to do it for you.
I don't have room in this book to coach you through a short course in irrigation design, but fortunately there's an alternative. All the major irrigation manufacturers have handy design and installation tutorials on their Web sites, and some of them can even create a design for you at a very modest cost. How cool is that? So if you were worried you'd have to become an instant engineer, chill. But just to get your bearings, look at Figure 6-6, which shows you what a finished irrigation plan looks like.
