Version 1.0 Issue Date: March 2024
This unit supports the attainment of skills and knowledge required for competent workplace performance in councils of all sizes. Knowledge of the legislation and regulations within which councils must operate is essential. The unique nature of councils, as a tier of government directed by elected members and reflecting the needs of local communities, must be appropriately reflected.
This unit covers providing support activity in the construction and maintenance of a water supply reticulation system.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
