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 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 Use 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 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.
using safety equipment and personal protective equipment
interpreting plans, service diagrams, charts, specifications, policies, standard operating procedures and plumbing and drainage standards
monitoring inflows
operating computerised equipment
identifying control system faults
investigating and reporting on odour and infiltration problems in the wastewater collection and transfer systems
inspecting and selecting tools and equipment
scheduling inspections
collecting and recording wastewater samples
investigating and reporting odour sources
integrating processes
managing flow regulations, diversions and isolation of the site
identifying, addressing and reporting illegal inflows or discharges
reviewing and addressing investigation results
completing required 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.
system hydraulics
monitoring processes
system layout, processes, operation
environmental aspects of wastewater collection systems and infrastructure
infiltration and inflow sources
policies, standard operating procedures and legislation
relevant utilities and service bodies
communication systems
environment, landscape and ground structure of work area
risk factors and potential hazards involved in wastewater collection systems equipment operation, capacity and limitations
effects of weather and conditions on operation of collection infrastructure
pipes and fittings
pumping and valving systems
gravity and control systems
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.
