Description
This unit of competency describes the skills and knowledge required to determine irrigation water needs, assess water quality of water source, determine cost and availability of alternative water sources and complete water sourcing or acquisition arrangements.The unit applies to individuals who apply specialised skills and knowledge to evaluate water supply for irrigation. 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. Determine water needs for irrigation
  • 1.1 Determine the water needs of plants to be irrigated
  • 1.2 Calculate the permeability of the soil and deep drainage losses
  • 1.3 Calculate evapotranspiration rates through the growing season
  • 1.4 Calculate soil water deficits throughout the season based on expected rainfall
  • 1.5 Calculate the amount of irrigation water required through the growing season
2. Assess a water source for water quality
  • 2.1 Test and record water source for electrical conductivity and analyse results
  • 2.2 Collect water samples for testing and interpret results
3. Determine cost and availability of alternative water sources
  • 3.1 Evaluate water availability and access requirements for water sources
  • 3.2 Cost capital expenditure requirements
  • 3.3 Cost operating expenditure requirements
  • 3.4 Investigate regulatory requirements for sourcing irrigation water and incorporate into business planning
4. Complete water sourcing or acquisition arrangements
  • 4.1 Make contractual arrangements for sourcing of water
  • 4.2 Plan for short term purchasing or selling of water depending on seasonal conditions if necessary
