- Requirements of liquid waste for classification as waste water.
- Trade waste certificate/permit conditions and requirements.
- Requirements of relevant regulatory body.
- Emergency and PPE requirements for work.
- Potential risks and hazards to waste water disposal.
- Drainage system capacity.

Specific skills needed to achieve the performance criteria
To achieve the performance criteria, some complementary skills are required. These are:
- communication including listening, questioning, following instructions, signalling, report writing
- reading and interpreting job requirements
- reading and interpreting gauges and indicators (including flowmeter)
- hazard identification
- safe and efficient work practices
- use of emergency and personal protective equipment
- working in confined spaces
- following MSDS.
Resources required to assess this unit
The following resources should be available:
- waste water for disposal
- flowmeter
- possession of trade waste certificate/permit
- access to waste water disposal system
- job sheet identifying disposal requirements
- personal protective equipment
- MSDS
- site safety plan.
Gaining evidence to assess this unit
For valid and reliable assessment of this unit, the competency should be demonstrated over a period of time and be observed by the assessor (or assessment team working together to conduct the assessment). The competency is to be demonstrated in a range of situations, which may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.
Evidence of competency is best obtained by observing activities in the field and reviewing the disposal of waste water to sewer. If this is not practicable, observations in realistic simulated environments may be substituted.
Consistency in performance
Assessment requires that strategies meet the objectives of clients and comply with industry expectations in the particular client environment. If the environment is narrowly defined or is not representative of industry needs, it will be necessary to assess the unit within a variety of waste management environments or different client needs to assess competency in the disposal of waste water to sewer.
Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge. (In assessment situations where the candidate is offered a preference between oral questioning and written audit, questions are to be identical.)
Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.
Note: All practical demonstrations must adhere to the safety and environmental regulations relevant to each state or territory.
