Coordinate and monitor the operation of wastewater collection systems

Assessment tool

Version 1.0
Issue Date: April 2024


This unit supports the attainment of skills and knowledge required for staff with a specific responsibility for ensuring that the operation of wastewater collection systems complies with organisational and statutory requirements. The level of responsibility may vary according to the size and complexity of the system.

This unit of competency describes the outcomes required to coordinate and monitor wastewater collection networks to ensure system performance, planning and maintenance conforms to targets outlined in the wastewater system management plan.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.

Employability Skills

This unit of competency contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

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

The candidate should demonstrate the ability to coordinate and monitor the operation of wastewater collection systems including:

interpreting the wastewater collection system management plan and confirming data to be gathered

identifying, analysing and addressing issues that impact on drainage systems, such as stakeholder requirements and environmental factors

accessing historic system information

conducting system performance monitoring and testing

analysing and reporting test results

investigating system faults and breaches of the wastewater collection system management plan and reporting results and recommendations

monitoring budgets, programs and targets, evaluating data and investigating and reporting on deviations from the wastewater collection system management plan

submitting recommendations to improve system performance and/or customer service standards.

Context of and specific resources for assessment

Access to the workplace and resources including:

documentation that should normally be available in a water industry organisation

relevant codes, standards, and government regulations.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.

Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
