Version 1.0
Issue Date: April 2024


This unit applies to workers in irrigated farming systems and is likely to be carried out under routine supervision within enterprise guidelines.

This unit covers the process of operating pressurised irrigation systems and defines the standard required to: read and follow operations manual and irrigation schedules; carry out pre-start checks; operate and inspect the system; measure and interpret flow rates and pressures; identify adverse environmental impacts of irrigation activities and take appropriate remedial action; shut down in response to irrigation indicators.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Checks of water, power, fuel and lubricants ensure that all are available and the control system is operational. 
Pumps are primed, if necessary, and valves and controls are open or closed as directed. 
Pressure and flow testing equipment are calibrated and available as required. 
Other pre-start system checks are carried out in accordance with manufacturer's requirements and enterprise procedures. 
Start up sequence is implemented in accordance with operations manual. 
All malfunctions, leaks and blockages are corrected or repaired immediately and reported in accordance with enterprise procedures. 
Pressure at the headworks and control valves is checked against design specifications 
Water distributed is checked for even coverage over the targeted areas with minimal wastage and run-off. 
Water is applied for sufficient time to achieve required soil moisture levels in accordance with irrigation schedule, environmental considerations and allowing for weather conditions. 
System components are shut down and drained in sequence in accordance with manufacturer's specifications and enterprise procedures. 
Drainage and treatment systems are checked in accordance with enterprise procedures. 
Irrigation activities are recorded and in reported accordance with regulatory requirements and enterprise procedures.
