Description
This unit of competency describes the skills and knowledge required to prepare a surface irrigation system for operation, develop and implement start-up, shutdown and isolation procedures, trouble shoot for faults and blockages, and measure and review surface irrigation system performance.The unit applies to individuals who apply specialised skills and knowledge to the management of surface irrigation systems and have responsibility for the output of others. This includes applying and communicating non-routine technical solutions to predictable and unpredictable problems.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1.Prepare surface irrigation system for operation
  • 1.1 Assess staff training needs for carrying out pre-start checks and routine servicing and arrange training for those that require it
  • 1.2 Program or adjust the irrigation controller to meet the required schedule
  • 1.3 Develop procedures for adjusting valves and checking outlets
2. Develop and implement start-up and shut down procedures for a surface irrigation system
  • 2.1 Develop start-up procedures for the system
  • 2.2 Provide training in priming pumps and setting gates to commence irrigating
  • 2.3 Develop shut down sequence and isolation procedures
  • 2.4 Specify soil conditions for operation and maintain tracks to reduce compaction
3. Measure performance of a surface irrigation system
  • 3.1 Identify and record variations in pressures at the head works and control valves
  • 3.2 Measure and record water flow rates according to workplace procedures
  • 3.3 Identify and record variations in water flow and distribution
  • 3.4 Measure and record pump performance parameters as necessary
  • 3.5 Measure and record variations in pump performance parameters where relevant
  • 3.6 Inspect distribution, drainage and water measurement systems
  • 3.7 Identify and repair system malfunctions and record actions
  • 3.8 Identify and record factors external to the system that may cause interference
4. Review system performance status
  • 4.1 Record system pressures and variations
  • 4.2 Record system flow rates and variations
  • 4.3 Calculate and record distribution uniformity and mean application rates
  • 4.4 Determine and record watering depth
  • 4.5 Measure quantity and quality of tail water, and amount of reused water
  • 4.6 Calculate and compare energy use and water efficiency to industry benchmarks
