Description
This Unit covers the process of managing a moving sprinkler irrigation system and defines the standard required to: develop procedures for system operation; troubleshoot faults and blockages; measure performance of the system; and benchmark energy and water efficiency of the system.
Notes
Elements and Performance Criteria
1 Ensure the moving sprinkler irrigation system is prepared for operation
  • 1.1 Staff are trained in carrying out pre-start checks and routine servicing
  • 1.2 The irrigation controller is programmed and/or adjusted to meet the required schedule
  • 1.3 Procedures are established for adjusting valves and checking filters and emitters
2 Develop and implement start-up and shutdown procedures for a moving sprinkler irrigation system
  • 2.1 Start-up procedures for a sprinkler irrigation system are developed according to system specifications and technical manuals
  • 2.2 Shut down sequence and isolation procedures are developed according to system specifications and technical manuals
  • 2.3 Soil conditions for operation are specified, or tracks maintained, to reduce compaction
3 Carry out trouble shooting for faults and blockages
  • 3.1 Access to faulty components and blockages is arranged
  • 3.2 Faulty components are removed from the system, according to system specifications and technical manuals, and repaired or disposed of in an environmentally responsible way
  • 3.3 Replaceable components are selected from manufacturer catalogues and procured using enterprise procedures
  • 3.4 Replacement components are installed to meet system specifications according to technical manuals
4 Measure performance of a moving sprinkler irrigation system
  • 4.1 Variations in pressures are identified and recorded in accordance with enterprise policy and procedures
  • 4.2 Water flow rates are measured and recorded in accordance with enterprise policy and procedures
  • 4.3 Variations in water flow and distribution are identified and recorded in accordance with enterprise policy and procedures
  • 4.4 Pump performance parameters are measured as necessary and recorded in accordance with enterprise policy and procedures
  • 4.5 Variations in pump performance parameters are measured where relevant and recorded in accordance with enterprise policy and procedures
  • 4.6 Distribution and delivery systems are inspected and malfunctions in system are identified, fixed and actions recorded in accordance with enterprise policy and procedures
  • 4.7 Factors external to the system that may cause interference are identified and recorded in accordance with enterprise policy and procedures
5 Review system performance status
  • 5.1 System pressures and variations are recorded in accordance with enterprise policy and procedures
  • 5.2 System flow rates and variations are recorded in accordance with enterprise policy and procedures
  • 5.3 Distribution uniformity and mean application rates are calculated and recorded in accordance with enterprise policy and procedures
  • 5.4 Watering depth is determined and recorded in accordance with enterprise policy and procedures
  • 5.5 Calculations are made for energy use and water efficiency and compared to industry benchmarks
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 irrigation systems may include:
moving sprinkler irrigation systems describe specifically hard and soft reel self-travelling irrigators, lateral move systems and centre pivots.
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.
