irrigation audits

Premier Landscape is a Certified Landscape Irrigation Auditor.

What is an Irrigation Audit? An Irrigation Audit produces detailed information about actual irrigation system performance in the field (as opposed to theoretical performance). This information is then used to prepare detailed irrigation schedules throughout the year. These procedures can be used to evaluate both new and existing irrigation systems.

Why Audit? The best irrigation efficiency is achieved when most of the water that is applied is used by the plants being irrigated. Improved efficiencies may result in:

  • Reduced water use and fewer dollars spent on your water
  • Improved landscape appearance; fewer wet or dry spots
  • Reduction of runoff
  • Reduction of water lost below the root zone (due to over watering)
  • Reduced fertilizer and chemical requirements

When should an Audit take place? Audits should be done periodically to evaluate system performance. An audit conists of a series of field procedures for collecting and compiling irrigation system data.  Then to evaluate the system performance characteristics, such as distribution uniformity and precipitation rates.

What should I expect after an Audit? After an audit, you or the irrigation technician in charge will have an appropriate irrigation schedule specific to your system. With appropriate irrigation scheduling, you will be putting down the right amount of water at the right time. A schedule defines the day or days of the week, the time or times of the day and how long a station or circuit is activated to apply water.

The recommended schedule resulting from an audit is based on the results of field tests and inspection, distribution uniformity and precipitation rate, soil intake rate, plant water requirement, root zone depth, and soil water holding characteristics. The schedule must be able to function within the limits and capabilities of the controllers used to operate the irrigation systems.

Schedules must be modified to accommodate changes in the weather, which change the plant’s need for water. If an onsite technician is not available to make adjustments on a daily basis, a weather station or ET sensor can be installed to do the job. Adjustment is better on a daily basis, as apposed to weekly, monthly, or seasonally.
