In the summer months, most water used in residential areas is applied to landscapes. Uniformity means every plant or soil surface receives the same amount of water. Irrigation uniformity is achieved through proper spacing and placement of sprinkler heads. By spacing sprinkler heads closer together than design specifications require, you can reduce water use and enhanced plant quality. Another factor to adjust in your irrigation system is water pressure.
Proper pressure helps minimize wind effects.
Excessive water pressure creates small particles of water which are easily moved away from the planned application pattern by wind. Distorted patterns mean some landscape area will require additional watering, even after sufficient water has gone through your system. By watering just after sunrise when wind is minimal, you can reduce the effect of wind. However, your system should be designed for the highest wind speeds expected during the growing season. Efficient irrigation systems also include a way to reduce runoff.
