Question 2

Which WaterSense program label applies specifically to irrigation professionals who demonstrate water-efficient design and management knowledge?

Accepted Answer

WaterSense Irrigation Partner (IrrigationPro)

Answer

The EPA WaterSense Irrigation Partner program (formerly IrrigationPro) recognizes irrigation professionals who have passed a qualifying third-party exam, such as the IA Certified Irrigation Technician (CIT) exam.

Question 3

Landscape water use efficiency (WUE) is expressed as the ratio of:

Accepted Answer

Water beneficially used to total water applied

Answer

WUE = beneficial water use / total water applied × 100%; the goal is to maximize plant water use and minimize waste from runoff, deep percolation, and evaporation.

Question 4

In a water budget approach to irrigation management, the maximum allowed water use (MAW) is based on:

Accepted Answer

A calculated ET-based water allowance for the landscape area

Answer

A water budget sets a maximum allowable water use tied to the landscape's ET requirement, incentivizing efficient scheduling to stay within the budget.

Question 5

Which certification exam does the Irrigation Association offer that is most focused on landscape irrigation system installation and maintenance?

Accepted Answer

Certified Irrigation Technician (CIT)

Answer
