Elements describe the essential outcomes. |
Performance criteria describe the performance needed to demonstrate achievement of the element. |
|
1. Ensure the surface irrigation system is prepared 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 filters and emitters |
|
2. Develop and implement start-up and shutdown 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 Record variations in pressures at the head works and control valves 3.2 Water flow rates are measured and recorded in accordance with enterprise policy and procedures 3.3 Measure and record water flow rates 3.4 Identify and record variations in water flow and distribution 3.5 Measure and record pump performance parameters as necessary 3.6 Measure and record variations in pump performance parameters where relevant 3.7 Inspect distribution, drainage and water measurement systems and identify and fix malfunctions in system 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 water reused 4.6 Calculate energy use and water efficiency and compare to industry benchmarks |
