Release 1. This is the first release of this unit of competency in the NWP National Water Training Package.

This unit involves the skills and knowledge required to operate and control chloramination processes.

It includes monitoring chloramination processes, measuring and reporting on system performance and process quality control. It also includes identifying faults, determining and applying technical adjustments.

This unit applies to operational staff with a specific responsibility for chloramination processes. Those undertaking this unit would work under appropriate supervision, while performing routine tasks, within a range of familiar contexts.

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

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all the requirements of the elements and performance criteria and includes knowledge of:

• chloramination process theory
• chlorine and ammonia dosing equipment
• control systems
• equipment operation, capacity and limitations
• microbiological aspects of water quality
• operational problems including nitrification
• reasons for chloramination
• risk factors and potential hazards associated with chloramination processes
• workplace policies and procedures, legislation and industry codes of practice

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

• relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry
• applicable documentation including legislation, regulations, codes of practice, workplace procedures and operation manuals.
