In this two-day course, students learn how to conserve water through landscape irrigation auditing. The course covers the steps of auditing, including prioritizing audit sites, conducting field tests to measure system performance, calculating irrigation schedules, and producing audit reports.
Topics include
- the use of potential evapotranspiration (PET) for determining turf water requirements,
- the effect of soil type and root zone depth on irrigation frequency, and
- calculation of irrigation system run times based on plant water requirements and system performance.
Students gain "hands-on" experience by performing two actual audits that include system troubleshooting, testing individual station performance, and identifying soil type and effective root depth.
Registration and completion of course includes copies of the LIAM software and manual. The software is only available to students upon completion of the class and is not for sale.
