Before You Design

To insure the most efficient irrigation system design, use a professional irrigation designer and installer. The Irrigation Association (IA) at www.irrigation.org certifies irrigation designers. The Oregon Landscape Contractors Board certifies irrigation installers.

If you decide to do it yourself, follow the steps below:

  • Call your local water provider for water pressure in your neighborhood. Knowing the site’s static water pressure is very important in the design of an irrigation system that works properly.

  • Determine the flow rate where the valve assembly will be connected.

  • Know your soil type. Different soils have different watering procedures.

  • Call your water provider for annual rainfall data, conservation materials, and many water-saving ideas for your garden.
