Irrigation system maintenance is necessary to ensure the most efficient use of the water that is being applied. Efficient irrigation is important because over two-thirds of the total water used in the average Utah home is applied to the landscape. With the natural drought cycles that occur in Utah and the growing population, efficient water use is critical. These maintenance recommendations will help you evaluate your irrigation system before using it each spring and also throughout the growing season.
