Description
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.
Notes
Elements and Performance Criteria
1 Carry out pre-start checks
  • 1.1 Checks of water, power, fuel and lubricants ensure that all are available and the control system is operational
  • 1.2 Pumps are primed, if necessary, and valves and controls are open or closed as directed
  • 1.3 Pressure and flow testing equipment are calibrated and available as required
  • 1.4 Regular maintenance is carried out
  • 1.5 Other pre-start system checks are carried out in accordance with manufacturer’s requirements and enterprise procedures
2 Inspect and operate the system
  • 2.1 Start up sequence is implemented in accordance with operations manual
  • 2.2 Emitter spacing is checked against the irrigation plan
  • 2.3 The transport mechanism is monitored and serviced
  • 2.4 The irrigation controller is checked for programming and efficiency
  • 2.5 All malfunctions, leaks and blockages are corrected or repaired immediately and reported in accordance with enterprise procedures
3 Monitor the irrigation operation
  • 3.1 The irrigation schedule is applied and soil profile monitored for wetting
  • 3.2 Sprinkler performance is measured using catch cans
  • 3.3 Flow rates are measured using containers of known volume
  • 3.4 Operating pressures are measured using pressure gauges
  • 3.5 The irrigated area is checked for wheel ruts and other signs of waterlogging
4 Shut down the system in response to irrigation indicators
  • 4.1 Water is applied for sufficient time to achieve required soil moisture levels in accordance with irrigation schedule, environmental considerations and allowing for weather conditions
  • 4.2 System components are shut down and drained in sequence in accordance with manufacturer’s specifications and enterprise procedures
  • 4.3 Drainage and treatment systems are checked in accordance with enterprise procedures
  • 4.4 Irrigation activities are recorded and reported in accordance with regulatory requirements and enterprise procedures
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.
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.
