NWPNET005
Optimise network systems


Application

This unit describes the skills required to coordinate, monitor and optimise system performance and maintenance planning in potable water distribution systems.

This unit applies to those working as staff members with a specific responsibility for ensuring that potable water systems comply with organisational and statutory 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.

Those undertaking this unit would work independently or in a team, and may be responsible for the coordination of an operational team. They will perform complex 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. Evaluate potable water distribution system performance

1.1 Review existing distribution system performance data against relevant organisational and legislative requirements.

1.2 Identify the impact of the distribution system on water quality.

1.3 Identify and coordinate any additional sampling and testing required for valid evaluation of current process performance.

2. Investigate water distribution system issues

2.1 Review existing system fault reports and relevant water quality information.

2.2 Identify and record links between operational problems and maintenance activities.

2.3 Investigate the operational status of system components with reference to manufacturer and supplier specifications.

2.4 Carry out distribution system configuration investigations to identify potential deficiencies.

3. Plan optimisation of potable water distribution system

3.1 Identify potential hazards to the distribution system.

3.2 Select appropriate preventive measures.

3.3 Develop and validate a system optimisation plan.

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.

producing optimisation reports

analysing problems and recommending appropriate remedial solutions

identifying risks and hazards

identifying opportunities for improved distribution system management

participating in the provision of appropriate information to inform workplace processes

optimising system performance and maintenance planning

assessing distribution system performance and impacts on water quality

investigating system faults and deficiencies and assessing the status of system components

conducting hazard assessment and proposing prevention strategies

producing and monitoring a potable water distribution system optimisation plan


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.

relevant legislation, standards, policies and procedures

customer expectations and requirements

system hydraulics

incident management processes

system layout, processes and operations

risk factors and potential hazards involved in water systems

equipment operation, capacity and limitations of control system

forces including gravitational, valve operation, hydraulic and pumps


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.
