UNIT TITLE

Manage pool water quality

APPLICATION

This unit describes the performance outcomes, skills and knowledge required to determine pool water maintenance, monitoring and treatment requirements using operational and regulatory specifications as the basis. It covers skills to monitor test data, and treat water on an ongoing basis. It requires the ability to evaluate water quality problems and contamination incidents, and to respond with corrective chemical treatments.

 

This unit applies to public aquatic facilities including those operated by commercial, not-for-profit, community and government organisations.

 

It applies to senior technical and operational staff and managers who work independently or with limited guidance from others, taking responsibility for their own work functions and outputs.

 

The skills in this unit must be applied in accordance with Commonwealth and State or Territory legislation, Australian standards and industry codes of practice.

 

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