Operate moving sprinkler irrigation systems

Assessment tool

Version 1.0
Issue Date: April 2024


This Unit applies to skilled workers in the irrigation servicing, and food and fibre production industries, and is likely to be carried out under routine supervision within enterprise guidelines.

This Unit covers the process of operating moving sprinkler 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)

Prerequisites

Not applicable.

Employability Skills

This Unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this Unit

The evidence required to demonstrate competency in this Unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

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 environmental hazards

shut down in response to irrigation indicators.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Moving sprinkler systems may include:

specifically hard and soft reel self-travelling irrigators, lateral move systems and centre pivots.

Moving sprinkler system components include:

spans

tower

tower wheels

outlets

emitters

droppers

pressure regulator

irrigation controller.

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 
Regular maintenance is carried out 
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 
Emitter spacing is checked against the irrigation plan 
The transport mechanism is monitored and serviced 
The irrigation controller is checked for programming and efficiency 
All malfunctions, leaks and blockages are corrected or repaired immediately and reported in accordance with enterprise procedures 
The irrigation schedule is applied and soil profile monitored for wetting 
Sprinkler performance is measured using catch cans 
Flow rates are measured using containers of known volume 
Operating pressures are measured using pressure gauges 
The irrigated area is checked for wheel ruts and other signs of waterlogging 
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 reported in accordance with regulatory requirements and enterprise procedures
