Irrigation audits are a key step in checking the efficiency of an irrigation system. Efficiency is achieved when most of the water from an irrigation system is actually used by the plants in the irrigated landscape. Conducting an irrigatin audit and the resulting irrigation efficiency results in several benefits.
* lower water use and lower water costs
* improved landscape appearance
* fewer wet spots and dry spots
* less water runoff
* less water lost below the plants roots
* less fertilizer needed
Irrigation audits should be done to evaluate an irrigation system's performance immediately after installation. Doing so will mean that any shortcomings found from the audit will more likely be addressed instead of waiting months to survey the installation.
