Welcome to Irrigation System Maintenance and How to Do a Performance Audit

An irrigation system audit is performed to determine the water application uniformity of the system. The audit confirms a good system design and good system operation. The audit may show that there are problems with the system; however, good maintenance should be done to the system before an audit so the audit is done when the system is at its best. Therefore, the procedure for doing an audit is to first check the system for maintenance to be done, complete that maintenance, and then do the audit to confirm good operation.

As background there is discussion of irrigation system design, irrigation efficiencies, application patterns, matched nozzles, water pressure, distribution uniformity and other topics related to irrigation system maintenance and good operating performance. These are all importance to understanding what makes a good operating system.
