Application
This unit describes the outcomes required to plan leak detection activities and to locate, identify and report leaks in water distribution networks (pressure mains).
This unit applies to those working as field staff with a specific responsibility for planning and implementing leak detection activities.
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.
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.
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 for leak detection | 1.1 Determine work site boundaries and leak detection requirements from plans, specifications and instructions. 1.2 Select and check equipment. 1.3 Plan for leak detection using site inspection and service search diagrams according to work site requirements. |
2. Operate leak detection equipment and report work | 2.1 Determine and mark work site boundaries from plans and service search diagrams. 2.2 Select, fit and use personal protective equipment. 2.3 Operate leak detection equipment. 2.4 Mark the location of leaks. 2.5 Expose leaks and arrange repair according to testing outcomes and organisational and statutory requirements. 2.6 Review, record and report work. |
Evidence of Performance
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.
analysing data to take remedial action
interpreting plans, specifications, policies and procedures
providing maintenance records for equipment
identifying safety risks and hazards
planning leak detection activities
locating, identifying and reporting leaks in water distribution networks
operating leak detection equipment
locating and marking leaks and arranging repair activities
completing documentation
Evidence of Knowledge
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.
basic calculation
identification, repair, lock out procedures
system hydraulics
system layout
environmental aspects
relevant utilities and service bodies
landscape and ground structure of work area
risk assessment and the identification of potential hazards
equipment operation, capacity and limitations
effects of weather and conditions on site or plant
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.
