Irrigation Checklist

Design

Visit the site and study the layout. Do not go only off the plot plans to design the irrigation system.
Take plant growth including trees and shrubs into account when designing and placing sprinklers and mirco-irrigation to help reduce future maintenance problems.
Make sure the irrigation design strives for ZERO over spray onto streets, driveways, sidewalks, enterances, parking areas, etc.
Design spacing of sprinkler heads with a minimum of "head-to-head" coverage
Use separate watering zones for areas with different water use needs
Work to avoid surface runoff. Different areas such as sloped areas may need different equipment or watering cycle times
Where appropriate use drip irrigation to save water

Installation

Contact appropriate local utility company to locate underground cables, telephone, gas or electric lines, etc.
If the irrigation design changes from the design plan or job requirments, discuss the changes with an irrigation system designer for any system or equipment adjustments
After installation – Test the system
