Unit Descriptor
This unit of competency describes the outcomes required to plan, prepare and conduct an inspection of gravity sewer or stormwater conduits, using specialised CCTV camera and transport systems, and reporting on observed defects and other features of the conduit in accordance with the industry code and job specifications. The ability to interpret technical information, identify and assess hazards, operate and maintain specialised technical equipment and produce computer generated reports on the condition and features of the conduit inspected are essential to performance.
Application of the Unit
This unit supports the attainment of skills and knowledge required for operators with a specific responsibility for: inspecting and reporting on the condition of operational gravity sewers and stormwater conduits and new or rehabilitated sewers or stormwater conduits; and operating and maintaining specialised CCTV inspection equipment in compliance with organisational and statutory requirements. This unit may also be applied to the inspection of other types of conduit system.
