Assessment tool
Version 1.0 Issue Date: April 2024
This unit of competency describes the skills and knowledge required to design irrigation, draining and water treatment systems.
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.
