Elements and Performance Criteria

1. Measure irrigation system performance
   • System pressures are measured and recorded in accordance with Occupational Health and Safety (OHS) and enterprise policy and procedures.
   • Variations in pressures are identified and recorded in accordance with enterprise policy and procedures.
   • Water flow rates are measured and recorded in accordance with enterprise policy and procedures.
   • Variations in water flow and distribution are identified and recorded in accordance with enterprise policy and procedures.
   • Pump performance parameters are measured as necessary and recorded in accordance with enterprise policy and procedures.
   • Variations in pump performance parameters are measured where relevant and recorded in accordance with enterprise policy and procedures.
   • Distribution and delivery systems are inspected and malfunctions in system are identified, fixed and actions recorded in accordance with enterprise policy and procedures.
   • Factors external to the system that may cause interference are identified and recorded in accordance with enterprise policy and procedures.
2. Monitor supply of equipment and spare parts
   • Supply and part usage are recorded in accordance with enterprise policy and procedures.
   • Spare parts meet demand.
   • Purchases are within budget constraints.
   • Parts requirements outside of budget constraints are reported.
   • Purchases and orders are recorded in accordance with enterprise procedures and systems.
3. Record and report system performance status
   • System pressures and variations are recorded in accordance with enterprise policy and procedures.
   • System flow rates and variations are recorded in accordance with enterprise policy and procedures.
   • Distribution uniformity and mean application rates are calculated and recorded in accordance with enterprise policy and procedures.
   • Watering depth is determined and recorded in accordance with enterprise policy and procedures.

Evidence Required

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 apply measuring and testing techniques measure pressures flows and distribution uniformity of an irrigation system calculate pressure differentials flow rates and water usage record and report system performance
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
