Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills required to maintain a variety of water distribution assets including storages, pumping stations, dosing stations and pipelines.

This unit applies to those working as field staff with specific responsibility for ensuring the repair and maintenance of water assets.

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.

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

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
