It is estimated that as much as half of the water applied to the landscape is wasted due to significant inefficiencies in watering practices and over-watering. Proper installation of irrigation systems obviously reduces the amount of waste that occurs but it is perhaps more important that an irrigation system is well maintained and its watering schedule tightly managed. In recent years, irrigation system audits that measure and evaluate irrigation systems have become increasingly popular among water providers, professional irrigators and users to address wasteful watering. They have also proven to save valuable plant material, hardscapes and equipment, while enhancing the aesthetics and resources used to maintain the landscape.
