Application
This unit describes the skills required to construct and install wastewater collection assets.
This unit applies to those working as field staff with specific responsibility for ensuring that wastewater pipelines are constructed and installed 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 manufacturer guidelines and WHS.
Those undertaking this unit would work independently or in a team using own familiar resources, while performing routine tasks in a range of familiar contexts.
No licensing, legislative or certification requirements apply to unit at the time of publication.
Elements and Performance Criteria
ELEMENTS | PERFORMANCE CRITERIA |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section. |
1. Plan and prepare construction and installation of collection pipelines | 1.1 Determine work requirements for construction and installation from plans, specifications and instructions. 1.2 Perform site check to prevent damage to other utilities. 1.3 Select and check equipment and tools required to meet safety requirements of task and site. 1.4 Identify potential risks to public and environment, and take appropriate steps to minimise and eliminate risks. |
2. Construct and install collection pipelines according to specifications | 2.1 Select, fit and use personal protective equipment. 2.2 Excavate and prepare trenches. 2.3 Lay bedding or foundation. 2.4 Select and lay or join pipes and fittings to grade. 2.5 Backfill excavations. |
3. Review construction and installation of collection assets | 3.1 Check constructed or installed collection pipes and fittings to ensure specifications are met. 3.2 Check, maintain and store equipment, tools and materials. 3.3 Restore work site to meet environmental and organisational requirements. 3.4 Complete workplace records as constructed drawings and process. |

Assessment Conditions
Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
