An irrigation audit – essentially –  is an evaluation of an irrigation system’s performance.   The results provide a road map on how to improve irrigation performance.

It takes a trained professional, knowledgeable in irrigation and the audit process, to develop an effective irrigation audit.

There are three steps in developing an irrigation system audit.

Step one – is to test the system to confirm that all of the irrigation system components are functioning properly.  Often times, significant water savings are achieved by simply fixing and adjusting the existing irrigation system.

Step two –  is to field test each zone of the irrigation system. Each irrigation zone is operated. The precipitation rate and efficiency of each irrigation zone is collected under actual operational conditions.

Step three – in an irrigation audit is to calculate irrigation schedules that are based on plant type, soil conditions, weather patterns, and field test results.

Gardeners’ Guild has had many years experience doing irrigation audits.  In fact, we’ve been a pioneer in the area of water management and have been recognized for numerous awards by the Marin Municipal Water District (MMWD).  We’ve played a leading role in the development of the Turf and Landscape Irrigation Best Management Practices.
