Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Required skills :

  • identify and report operational problems
  • collect and report system performance information
  • inspect flow regulation, measuring and regulating devices
  • produce reports and logs
  • use communication systems
  • give and receive instructions
  • interpret plans, charts and instructions
  • interpret policies, procedures and standards
  • communicate with customers and other employees
  • use personal protective equipment

Required knowledge :

  • monitoring flow control, measuring and regulating devices' performance
  • system hydraulics
  • system layout
  • relevant utilities and service bodies
  • communication systems
  • materials handling
  • environmental, landscape and ground structure of water distribution and/or wastewater collection systems
  • system and network risk factors and potential hazards
  • equipment operation, capacity and limitations
  • effects of weather and conditions on operation of system and site
  • flow measurement procedures
  • data collection and recording
  • system flow control mechanisms and control systems
  • where relevant, lock out procedures for mechanical and electrical installations

Evidence Guide

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 to monitor the operation of complex flow control, measuring and regulating devices including:

  • interpreting work requirements and selecting appropriate equipment and tools, including personal protective equipment
  • identifying devices and equipment to be monitored and relevant operational specifications
  • collecting and recording information on device performance
  • conducting minor routine maintenance tasks and secure devices
  • identifying and reporting problems and anomalies
  • inspecting system and networks
  • collecting and recording data on system performance
  • taking samples
  • reporting monitoring and inspecting findings
  • identifying and reporting on system performance

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/or 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, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
