To achieve this goal most spray head zones (sprinklers that do not rotate) need to run approximately 15 minutes and rotor zones (sprinklers that do rotate) need to run approximately 45 minutes. If you have much slope on your lawn areas you may need to run 2 cycles but with shorter run times on the zones.
Overhead sprinklers waste a lot of water due to evaporation, but if yours is adjustable, be sure to aim it at the base of plants. Allow a garden hose to run a pencil thin stream of water at the base of trees and shrubs for 30 minutes to an hour. This small stream of water soaks slowly and deeply in the soil to the roots. To test how deeply the water goes, stick a trowel, spade, knitting needle or soil probe into the ground.
