Arizona Irrigation & Backyard Drainage Guide
Water is scarce in Arizona, but intense storms and irrigation leaks can still damage landscapes. Drainage and watering should be designed together.
Read the existing grade
Identify high and low points, roof discharge, wall openings and the direction water currently travels before adding patios or turf.
Keep water away from structures
Finished grades should support drainage away from the home while respecting neighboring lots, walls and approved discharge paths.
Match emitters to plants and soil
Emitter flow and placement should wet the root zone without creating constant shallow moisture at trunks or foundations.
Inspect, do not just automate
Controllers cannot detect every broken line, clogged emitter or displaced outlet. Walk the system and look for abnormal growth, dry spots and pooling.
