The above provides a brief description of different categories of Live Sewer Works, its scope and any prerequisite required for entry into different categories covered by this registration scheme.

Please note that non-commissioned sewers and associated structures may still be considered as confined spaces under the definition of the Victoria WorkSafe Code of Practice for Confined Spaces.

Use of Subcontractors

Contractors shall ensure that their subcontractors are registered in the appropriate category for the subcontracted Live Sewer part of the project.

Contractors entering into a subcontract with a subcontractor for which there is no registration category are responsible for the competence of that subcontractor and must therefore satisfy themselves that the subcontractor has appropriate qualifications, expertise and experience.
