Elements and Performance Criteria

1. Determine the feasibility of using or up-grading irrigation system
   • Assess water resources and drainage implications to determine suitability for irrigation
   • Determine water quality and treatment requirements
   • Determine water requirements and most suitable application systems for each crop and plant type and area, and for each soil type
   • Determine other water requirements, such as climate control
   • Assess soil types to determine suitability for irrigation and the range of crop and plant types that could be grown
   • Determine drainage requirements in relation to each soil and crop and plant type and type of irrigation system
   • Assess performance data, audit reports, environmental and workplace health and safety data for existing systems
   • Obtain information from irrigation specialists on all relevant aspects of irrigation design
   • Assess and cost available irrigation system types and components and make a decision on the particular system to be used or upgrades to existing system
2. Install or modify an irrigation and drainage system as necessary
   • Determine and acquire materials and equipment making up the system
   • Install irrigation system using advice, as necessary, from irrigation specialists
   • Check that irrigation and drainage systems are supervised to ensure there are no leaks or blockages
   • Confirm that the water is being evenly distributed and that the drainage is effective and the system is in good working order
3. Evaluate irrigation system performance
   • Determine and value plant growth and yield increases from irrigation
   • Calculate the cost of irrigation
   • Determine the cost benefit of irrigation and compare with alternative systems and approaches
