ITRC: Basic Hydraulics
Intermediate | Landscape | 3 CEUs
This module details the core principles of how and why water moves in an irrigation system. In this module you will learn some of the basic terms as you study static and dynamic conditions. You will also learn about the equation that is used to account for the energy in a system and some basic design considerations. This class qualifies for 3 New Jersey CECs/WC AND 2 North Carolina CEs.

ITRC: Basic Soil-Plant-Water Relationships
Intermediate | Landscape | 2 CEUs
This module explains the basic relationships between water, plants and soil. Topics include soil moisture content terms, available water-holding capacity, management allowable depletion, soil moisture depletion and soil water potential. This class qualifies for 2 New Jersey CECs/WC and North Carolina CEs.

ITRC: Distribution Uniformity & Precipitation Rate
Intermediate | Landscape | 1.5 CEUs
Two of the most important concepts in landscape irrigation are distribution uniformity and precipitation rate. DU refers to how evenly water is applied to a landscape. It is used to measure the performance of an existing irrigation system and is determined through a catch can test. Precipitation rate identifies the rate at which irrigation water reaches the ground surface, and it is affected by sprinkler flow rate and area of coverage. PR is an important value that is used in both system design and irrigation scheduling. This class qualifies for 1½ New Jersey CECs/WC and North Carolina CEs.

ITRC: Evapotranspiration
Intermediate | Landscape | 1 CEU
A plant’s evapotranspiration rate defines how quickly water is transpired through the plant and evaporated from the soil surface. The ET rate varies based on a variety of different factors and is an important component of a good irrigation schedule. This class qualifies for 1 New Jersey CEC/WC and North Carolina CE.

ITRC: Irrigation System Components
Beginner | Landscape | 3 CEUs
The success of an irrigation system design depends on an understanding of the components of an irrigation system and how they work within the system. Irrigation systems vary by location, size and type, but there are several general categories of components that you will need to be familiar with before designing a system. This class qualifies for 3 New Jersey CECs and North Carolina CEs.

ITRC: Landscape Irrigation Auditor
Intermediate | Landscape | 4 CEUs
Irrigation auditing is a method for inspecting and measuring how effectively sprinklers are working to apply water evenly within an irrigated area. This module goes over the five basic steps of preparing for and performing an audit on a landscape irrigation system. This class qualifies for 4 New Jersey CECs/WC and North Carolina CEs.

ITRC: Landscape Sprinkler Design
Advanced | Landscape | 8 CEUs
This module outlines the nine basic steps of creating a workable landscape irrigation system design. The program begins with collecting site data and covers computing component sizes, choosing locations for components and calculating runtimes. This class qualifies for 8 New Jersey CECs/WC and North Carolina CEs.

ITRC: Scheduling for Auditors
Intermediate | Landscape | 2 CEUs
The Irrigation Association provides three simple worksheets to help an auditor create an irrigation schedule: the simple schedule worksheet, the designated watering days schedule worksheet and the soil moisture irrigation schedule worksheet. This module goes over each of the three worksheets and gives an overview of what to expect from the system controller. This class qualifies for 2 New Jersey CECs/WC and North Carolina CEs.

ITRC: Scheduling for Sprinkler Design
Advanced | Landscape | 1.5 CEUs
This module contains four tutorials that discuss scheduling irrigations after you have designed a system. The course teaches when to water, how much to water and what to expect from a system controller. This class qualifies for 1½ New Jersey CECs/WC and North Carolina CEs.
