Construct and install irrigation delivery and stormwater drainage assets


Application

This unit of competency describes the skills required to construct irrigation delivery or stormwater drainage assets on site and to install both constructed assets and prefabricated components.

This unit applies to those working as field staff with specific responsibility for ensuring that the construction and installation of irrigation or stormwater drainage assets is completed in a safe and timely manner.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to, particularly those related to WHS.

Those undertaking this unit would work under indirect supervision, while performing routine tasks and ensuring minimum damage to the environment, in a familiar context.

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