Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Equipment used includes:
personal protective equipment
electronic digital monitoring and metering systems
basic hand and power tools
valves, pumps and flow meters
mechanical meters and flow devices
hydrants
recording systems
communication equipment, including:
two-way radio
telephone
fax
lifting and winching equipment
on- and off-road vehicles
Processes to ensure flows are monitored, measured and recorded may require:
interaction and communication with other employees, other authorities and general public
visual observation
implementation of reporting procedures that may also include procedures for implementation of by-laws, organisational policies and statutory requirements
Designated locations and systems may include:
urban locations
rural locations
ground and surface water source systems
wastewater collection and transfer systems
trade waste systems
Flow regulation may involve operation of:
valving systems, including:
sluice
blade
gate
non-return
pressure reducing
supervisory control and data acquisition (SCADA) systems
pumping systems, including:
centrifugal
Archimedes screw type
submersible
positive displacement
electronic and manual controlling systems
service reservoirs
Legislative and organisational requirements may include:
relevant federal and state or territory legislation and regulations
codes of practice, associated standards and guidance material
documented organisational policies, manuals and induction programs
relevant community planning and development agreements, such as land care agreements

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The candidate should demonstrate the ability in water and wastewater treatment network systems to:
identify flow requirements
prepare for and conduct flow monitoring
identify and report operational problems
adjust and regulate flows according to organisational requirements
complete records and reports
Context of and specific resources for assessment
Access to the workplace and resources including:
documentation that should normally be available in a water industry organisation
relevant codes, standards and government regulations
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.
