Test and commission wastewater collection systems

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the outcomes required to plan and implement the testing and commissioning of wastewater collection systems. The ability to interpret technical information, identify and assess hazards and perform technical testing procedures is essential to performance.

This unit applies to those working as field staff and operators with specific responsibility for commissioning wastewater collection systems, post-installation or repair, and for ensuring that the functioning of the system complies with relevant specifications and organisational requirements.

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 WHS, and manufacturer specifications.

Those undertaking this unit would work under indirect supervision, while performing routine tasks in a familiar context, ensuring minimum damage to the environment.

No licensing, legislative or certification requirements apply to unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 testing and commissioning

1.1 Identify and interpret the system operation requirements.

1.2 Confirm and schedule testing and commissioning tasks.

1.3 Identify and assess potential hazards and take required preventative measures.

1.4 Select and use tools and equipment.

1.5 Check testing equipment for accuracy and correct malfunctions.

2. Conduct pipeline and access structure testing procedures

2.1 Select and install tensioning and measuring equipment.

2.2 Select and fit gauges of the correct range to test equipment.

2.3 Carry out testing procedures.

2.4 Locate failed pipes, joints and fittings and reschedule reporting and testing.

2.5 Locate and report failed maintenance holes, inspection shafts, maintenance shafts or other access structures and reschedule further testing.

3. Commission the wastewater collection system.

3.1 Ensure the system is operational.

3.2 Restore the work site.

3.3 Check, maintain and store equipment tools and materials.

4. Record and report results

4.1 Maintain workplace and calibration records and certificates.

4.2 Collect and store all testing and compliance results.

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

monitoring work processes and ensuring safe work practices

identifying, reporting and recording hazards and risks

using personal protective equipment

participating in ensuring compliance with standards, regulations and policies

maintaining and checking records and documents

planning and implementing the testing and commissioning of wastewater collection systems

interpreting the testing requirements of the system from relevant plans and documentation

preparing and checking testing equipment

assessing risks and hazards and taking appropriate preventive measures

using testing equipment

applying testing procedures

identifying and reporting faulty system components

making the system operational and conducting post-commissioning checks

restoring the worksite

completing relevant documentation

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.

WHS on work sites

the risk factors and potential hazards of test procedures

characteristics of pipes, materials and fittings

an overview of wastewater system and water industry operations

layout and construction of wastewater collection systems

testing procedures for wastewater systems

relevant definitions, terminology, symbols and language

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.
