Application

This unit of competency describes the skills and knowledge required to interpret the irrigation design for an installation site.

It applies to individuals who analyse information and exercise judgement to complete a range of skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

Pre-requisite Unit

  • mark out procedures
  • interpret technical drawings and site plans
  • calculate pressures, flows, velocities and friction losses
  • determine efficiency of the system with varying system components

Knowledge Evidence

The candidate must demonstrate knowledge of:

  • principles and practices of irrigation design interpretation
  • erosion control and design principles
  • how to interpret plans and general and technical specifications
  • hydraulic calculations
  • levels and levelling
  • principles of native topsoil conservation and protection
  • pumps and pumping system components
  • relevant work health and safety and environmental requirements
  • selection of water pumping and distribution components delivery based on specifications and requirements

Assessment Conditions
