Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1Monitor distribution system performance. | 1.1 Conduct routine inspections of supply networks and report faults according to organisational procedures. 1.2 Select equipment and inspection methods to meet task and site safety requirements. 1.3 Collect data on system performance and usage and report according to legislative and organisational requirements. |
2Monitor water quality. | 2.1 Collect and record water samples according to organisational requirements. 2.2 Monitor water quality according to organisational requirements. |

Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: identify and respond to operational problems produce reports and logs use safety and personal protective equipment use tools and machinery follow plans, instructions and policies perform system calculations apply inspection and testing procedures and standards communicate with employees and customers use communication equipment give and receive instructions work effectively as part of a team identify system faults use literacy skills in regard to verbal and written communication in the workplace identify hazards. |
Required knowledge: system hydraulics basics system layout system calculations environmental aspects of maintenance lock-out procedures for mechanical and electrical installations relevant utilities and service bodies communication systems hazardous materials handling landscape and ground structure of work area risk management principles risk factors and potential hazards of inspection processes equipment operation, capacity and limitations effects of weather and conditions on system operation and plant control systems pipes and fittings. |
Evidence Required
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 inspect water distribution systems, detect faults and report on water distribution system performance including: monitoring and reporting on performance of water distribution systems, including water quality identifying and reporting leakages or damage to system components identifying and reporting operational conditions falling outside performance specifications processing consumer complaints. |
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 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. 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. |
Range Statement
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. | |
Routine inspections may include: | interaction and communication with other employees, other authorities and general public visual observation implementation of reporting procedures that may also include procedures for implementation of by-laws, organisational policies and statutory requirements. |
Supply networks may include: | distribution system pipe work, including: polyvinyl chloride (PVC) polyethylene mild steel cement lined ductile iron cement lined cast iron cement lined asbestos cement copper glass reinforced piping structures, including: meter pits person access chambers or pits valve chambers regulators erosion barriers head walls thrust blocks pumping stations consumer services meters fittings, including: hydrants sluices valves scours main taps jointing systems for pipe types, e.g. gibault tapping bands tension bands solvent cement joints compression ring joints bolted flanges electrofusion butt welding backflow prevention devices cathodic protection. |
Equipment may include: | hand and power tools lifting equipment mechanical excavation equipment electronic monitoring and metering systems recording systems motorised equipment on- and off-road vehicles communication equipment breathing apparatus gas detection equipment rescue equipment appropriate personal protective equipment. |
Legislative and organisational requirements may include: | 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. |
System faults may include: | loss of pressure leakage odour turbidity and colour loss of flow. |
