Unit of Competency NWPTRT001 - Operate and control water treatment processes
Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills required to operate and control a water treatment plant, to report on water treatment plant system performance and process quality control. The ability to operate water treatment processes in urban and/or rural areas, in compliance with relevant water legislation and regulations and Australian Drinking Water Guidelines, is vital to performance.This unit applies to those working as operational staff in water treatment plants with responsibility for the practical and safe operation of plant, equipment and processes.The skills and knowledge described in this unit must be applied within the legislative, statutory, 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 under supervision, while performing routine tasks, within a familiar context.No licensing, legislative or certification requirements apply to unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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.
