Application
This unit describes the skills required to construct and install water distribution assets.
This unit applies to those working as field and operational staff with responsibility for ensuring that water distribution assets 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 specifications, environmental requirements, WHS, construction and disinfection.
Those undertaking this unit would work independently or in a team using own familiar resources as required, while performing routine tasks in range of familiar contexts, ensuring minimum damage to the environment.
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 for construction and installation | 1.1 Determine work requirements for construction and installation of water distribution system pipes and assets from plans, specifications and instructions. 1.2 Perform site checks to prevent damage to other utilities. 1.3 Select and check equipment and tools to meet safety and work requirements of task and site. 1.4 Select, fit and use personal protective equipment. |
2. Construct and install distribution assets, pipes and associated fittings | 2.1 Excavate and prepare trenches. 2.2 Lay bedding or foundation. 2.3 Inspect pipes and fittings, and lay or join them. 2.4 Install or place prefabricated components. 2.5 Backfill excavations according to specifications. |
3. Confirm work quality | 3.1 Check constructed and installed distribution assets, pipes and fittings to ensure that specifications are met. 3.2 Check water quality testing results to ensure that organisational requirements are met. |
4. Finalise work | 4.1 Check, maintain and store equipment, tools and materials. 4.2 Restore work site. 4.3 Complete workplace records and as constructed drawings, and process as required. |
