Elements and Performance Criteria

1. Ensure the irrigation is prepared for operation
   • Assess staff training needs for carrying out pre-start checks and routine servicing and arrange training for those that require it
   • Program or adjust the irrigation controller to meet the required schedule
   • Develop procedures for adjusting valves and checking filters and emitters
2. Develop and implement start-up and shutdown procedures
   • Develop start-up procedures
   • Develop shut down sequence and isolation procedures
   • Install safety or security lock off devices and signage
   • Provide instructions for flushing the system as required
3. Carry out trouble shooting for faults and blockages
   • Arrange access to faulty components and blockages
   • Remove faulty components and repair or dispose of
   • Select appropriate replaceable components and install
4. Measure performance of the system
   • Identify and record variations in pressures
   • Measure and record water flow rates
   • Identify and record variations in water flow and distribution
   • Measure and record pump performance parameters as necessary
   • Measure and record variations in pump performance parameters where relevant
   • Inspect distribution and delivery systems and identify and fix malfunctions in system and record actions
   • Identify and record factors external to the system that may cause interference
5. Review system performance status
   • Record system pressures and variations
   • Record system flow rates and variations
   • Calculate and record distribution uniformity and mean application rates
   • Determine and record watering depth
   • Calculate energy use and water efficiency and compare to industry benchmarks
