Monitor and report wastewater treatment processes
Assessment tool
Version 1.0
Issue Date: May 2024
This unit supports the attainment of skills and knowledge required for operational staff in wastewater treatment plants with responsibility for monitoring wastewater treatment processes.
This unit of competency describes the outcomes required to monitor and report on wastewater treatment processes within domestic and industrial wastewater treatment plants in urban and rural areas. The ability to monitor processes to ensure that wastewater disposal or re-use meets state or territory licensing requirements is essential to performance.
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 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 tomonitor and report on wastewater treatment processes within domestic and industrial wastewater treatment plants in urban and rural areas including: performing, recording and reporting process measurements and calculations demonstrating procedures for starting and stopping plant and locking out control equipment adjusting process controls according to specific plant procedures recording and reporting faults and breakdowns identifying common process faults and following procedures to rectify these |
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 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 only taken at the point 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 In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |

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.
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: apply policies, procedures and standards recognise and report operational problems use safety equipment and personal protective equipment select, collect and test samples interpret material safety data sheets (MSDS) receive and apply instructions use literacy skills in regard to verbal and written communication in the workplace communicate with other employees and people that interact within the work environment |
Required knowledge: sources of wastewater physical, chemical and microbiological characteristics and operating principles related to wastewater treatment reasons for wastewater treatment types of wastewater treatment plant processes major chemicals and equipment used wastewater treatment plant hazards safety equipment reasons for data and information collection |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts. | |
Wastewater sources may include: | domestic industrial storm ground |
Reasons for treatment may include: | ensuring conformity with legislation, regulations, standards and codes removal of impurities and contaminants to enable discharge or re-use reducing impact of impurities on the environment and public health |
Statutory requirements are defined by: | relevant federal and state or territory legislation and regulations codes of practice, associated standards and guidance material documented organisational policies, manuals and induction programs relevant community planning and development agreements, such as land care agreements |
Wastewater treatment processes may include: | grit removal aeration screening sedimentation disinfection granular and membrane filtration thickening and dewatering suspended and fixed media aerobic bioreactor processes anaerobic processes lagoons and wetlands gas scrubbers biosolids and effluent disposal and re-use dilution chemical dosing nutrient removal reverse osmosis |
Characteristics of wastewater may include: | types of impurities, such as: organic inorganic micro-organisms public health considerations |
Equipment used may include: | pumps, including: centrifugal positive displacement airlift blowers screens control valves electronic digital monitoring systems recording systems chemical testing and analysis equipment communication equipment belt press centrifuge comminutor flow meters flow recorders manual or hydraulic equipment personal protective equipment |
Chemicals and major equipment used may include: | chemicals and lime sodium hypochlorite aluminium and iron coagulants polymers |
Data may include: | instantaneous flow rate flow records temperature sand and grit pH chemical oxygen demand dissolved oxygen settleable solids concentration (cone test) thirty minute settleability test sludge blanket level residual chlorine microscopic examination conductivity |
Process calculations may include: | average dry weather flow peak dry weather flow chemical feed rate and concentration process efficiency |
Wastewater quality parameters may include: | physical chemical microbiological |
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.
