CPPWMT3051A
Dispose of waste water to sewer

This unit of competency specifies the outcomes required to conduct batch disposal of waste water to sewer. Waste water may be the outcome of treatment at a waste processing facility, treatment plant or industry source. It requires the ability to apply safe work practices.

Application

This unit of competency supports individuals with responsibilities for conducting waste management activity. It includes contributing to the implementation of developed operational procedures, as well as recognising the need for expert advice.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

This unit of competency could be assessed by observation of practical demonstration in the workplace or in a simulated environment, enabling the disposal of waste water to sewer.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person who demonstrates competency in this unit must be able to provide evidence of the required skills and knowledge specified in this unit.

In particular the person should demonstrate the ability to:

comply with regulators and organisational requirements for the disposal of waste water to sewer

organise equipment and personnel requirements

monitor operation of drainage system during disposal to sewer

maintain disposal system to prevent blockages, contamination and leakages

monitor discharge to alleviate system backlogs

observe OHS requirements.

Context of and specific resources for assessment

Assessment of essential underpinning knowledge may be conducted in an off-site context. It is to comply with relevant regulatory or Australian standards’ requirements.

Resource implications for assessment include:

work plans and approved specifications

forms and procedures manuals.

Method of assessment

The process of disposing waste water to sewer must comply with industry expectations in the particular client environment. If the environment is narrowly defined or is not representative of industry needs, it may be necessary to refer to portfolio case studies to assess competency in the disposal of waste water to sewer.

Assessment methods must:

satisfy the endorsed Assessment Guidelines of the Property Services Training Package

include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

reinforce the integration of employability skills with workplace tasks and job roles

confirm that competency is verified and able to be transferred to other circumstances and environments.

Guidance information for assessment

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

This unit could be assessed on its own or in combination with other units of competency relevant to the job function, for example:

CPPCMN3003A Contribute to workplace safety arrangements

CPPWMT3044A Identify wastes and hazards.
