Application

This unit describes the skills required to identify and apply to water systems and processes the principles of chemistry, and to select the relevant and effective chemicals required for specific processes.

This unit applies to a range of operational roles within the water industry and is fundamental to all quality monitoring and treatment processes.

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.

Those undertaking this unit would work independently while performing complex tasks within a range of contexts.

No licensing, legislative or certification requirements apply to unit at the time of publication.

These Assessment Requirements were released in NWP Water Training Package release 1.0 and meet the Standards for Training Packages.

  • Assessment Requirements created drawing upon specified assessment information from superseded unit

Performance Evidence

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.

  • interpreting a range of complex and technical documents including relevant:
  • regulatory, legislative, licensing and organisational requirements
  • codes and standards
  • specifications
  • organisational policies
  • analysing and evaluating reports and reference materials
  • performing various calculations to provide data for the analysis and development of options and solutions
  • identifying risks and hazards

Knowledge Evidence

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.

  • standards and workplace policies and procedures determining the use and management of chemical processes
  • chemical concepts relevant to water industry processes
  • chemical reactions
  • range and characteristics of chemicals used in various water industry processes
  • functions of various chemicals in water industry processes
  • factors influencing the effectiveness of chemicals
  • factors affecting the selection of chemicals

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.
