Version 1.0
Issue Date: May 2024
This unit supports the attainment of skills and knowledge required for operational staff in water treatment plants with responsibility for monitoring and reporting on water treatment processes.
This unit of competency describes the outcomes required to monitor and report on water treatment processes within potable community and industrial water treatment plants in urban and rural areas.
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 monitor and report on water treatment processes within potable community and industrial water treatment plants in urban and rural areas including: identifying characteristics and importance of water quality establishing organisational water quality standards checking and recording water quality characteristics applying safety procedures in a potable water treatment plant collecting and recording routine data on water treatment plant processes. |
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: operating principles of water treatment processes basic water chemistry water uses and demands, both domestic and industrial physical, chemical and microbiological characteristics of water within the water treatment process water quality guidelines reasons for water treatment types of treatment plants and processes major chemicals and equipment used physical and chemical hazards 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. | |
Reasons and requirements for water treatment include: | ensuring conformity with standards and guidelines, including Australian Drinking Water Guidelines removal of impurities, contaminants and pollution impact of impurities on water treatment processes relevant water and environment legislation and regulations hazard analysis critical control point (HACCP) operational philosophy. |
Water treatment processes may include: | screens coagulation and flocculation sedimentation clarification dissolved air flotation granular and membrane filtration disinfection aeration and oxidation fluoridation reverse osmosis ion exchange activated carbon adsorption calibration of dosing equipment softening backwash water treatment. |
Water quality characteristics may include: | physical chemical microbiological. |
Equipment used may include: | pumps, including: centrifugal positive displacement airlift blowers and compressors mixers and chemical batching facilities control valves electronic digital monitoring systems recording systems chemical testing and analysis equipment communication equipment manual or hydraulic equipment personal protective equipment. |
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.
