NWPTRT073
Operate and control wastewater sedimentation processes

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills required to monitor and operate non-chemically assisted sedimentation processes within domestic and industrial wastewater treatment plants or stormwater systems. The required outcomes also include reporting on the sedimentation system performance and process quality control within these systems.

This unit applies to those working as operational staff with responsibility for checking that sedimentation processes comply with organisational performance requirements.

The skills and knowledge described in this unit must be applied within the legislative, 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 in a range of familiar contexts.

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

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


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.

ELEMENTS

PERFORMANCE CRITERIA

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section.

1. Plan and prepare for work

1.1 Determine work requirements as outlined in the standard operating procedure.

1.2 Select and check equipment required to meet safety requirements of task and site.

1.3 Select, fit and use personal protective equipment.

2. Monitor and operate sedimentation processes

2.1 Carry out sedimentation process inspections according to type of plant.

2.2 Collect process samples and conduct standard tests.

2.3 Monitor processes to maintain parameters of operation.

2.5 Identify and report process faults and operational condition of plant.

2.6 Carry out basic system adjustments to enhance system performance.

3. Complete documentation

3.1 Collect and report process data.

3.2 Report observations outside defined parameters for further action.

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

performing system calculations

applying procedures and standards

giving and receiving instructions

identifying control system faults and operational problems

using verbal and written communication in the workplace

sampling and testing products

monitoring, operating and reporting on sedimentation processes

conducting routine plant inspections

reporting process and structural faults

performing system adjustments

completing system performance monitoring documentation

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.

principles that form the basis of sedimentation processes

system layout

lockout procedures for mechanical and electrical installations

policies, procedures and legislation relating to wastewater treatment

communication systems

risk factors and potential hazards

basic system calculations

equipment operation, capacity and limitations

effects of changes in hydraulic load on sedimentation processes

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
