NWPNET042
Monitor and operate wastewater collection and transfer systems


Application

This unit describes the outcomes required to monitor and coordinate the operation of wastewater collection and/or wastewater transfer systems and to measure and report on the operation of the system. The ability to interpret technical documentation, identify and investigate operational problems and to collect and analyse technical information is essential to performance.

This unit applies to those working as field staff and operators with a specific responsibility for inspecting and measuring the performance of wastewater collection and/or wastewater transfer systems and for ensuring that flows are regulated according to organisational specifications and system demands.

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.

1.3 Collect, analyse and report system performance and usage data.

1.4 Monitor and coordinate sample collection and records.

2. Regulate flows

2.1 Inspect and adjust flow regulating systems.

2.2 Monitor and adjust volumes.

2.3 Monitor flows and diversions required for repair or emergency activities.

3. Operate and control processes

3.1 Control and improve processes to maintain operating parameters.

3.2 Conduct wastewater flow measurements.

3.3 Identify, address and report process faults.

3.4 Optimise process performance.

4. Compile process records

4.1 Compile reports from system data.

4.2 Record the condition of equipment and report faults or anticipated problems.

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.

responding to and correcting operational problems

interpreting plans, charts, service search diagrams, instructions, policies and specifications

controlling system operations

identifying control system faults

monitoring and coordinating the operation of wastewater collection and/or wastewater transfer systems

preparing equipment for monitoring and inspections

monitoring the system and collecting, analysing and reporting data according to organisational procedures

reviewing samples and records

adjusting flow regulating systems

monitoring volumes and flows

controlling, integrating and optimising processes

identifying and reporting process faults

measuring wastewater flows

completing relevant workplace 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.

system hydraulics

coordination and control of processes

system layout and processes

environmental aspects of wastewater collection and transfer systems

infiltration and inflow sources

illegal inflows

discharges

disinfection and chemical use

policies, standard operating procedures and legislation

relevant utilities and service bodies

communication systems

risk factors and potential hazards involved with wastewater pressures and flows

equipment operation, capacity and limitations

effects of weather and conditions on operation of collection and transfer systems

pipes and fittings

gravity systems

pumping and valving systems

control systems

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.
