Elements and Performance Criteria

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. 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.


Plumbing design and fixtures may include:
Pipes, e.g. copper and poly
Indoor and outdoor taps
Bath, shower
Water trough
Hand basin
Kitchen sink
Toilet cistern
Stop cock or cistern cock
Breech piece to connect hot and cold water

Leaking water supply pipes or valves because of cracks, corrosion or poor installation
Broken down or worn out pumps
Corrosion, cracks and leaks in water/storage tanks
Excessive organic matter/sludge collecting on the bottom of tanks
Broken lids on tanks
Aggressive water supply, particularly in tropical areas, e.g. may need special plastic fittings and more maintenance of all parts of the water supply
Leaking taps
Leaking toilet cisterns
Non functioning hot water service


Identify strategies within the workers own roles and responsibilities may include:
Education/health promotion to householders and community members as part of job role
Repairs and maintenance to household and community plumbing and fixtures, e.g. fixing leaking taps, maintaining toilet cisterns, etc.
Monitoring water supply and checking for signs of possible contamination either at the source such as a river or bore, in storage such as elevated tanks, or in the pipe system which delivers water to the user
Maintaining water supply system, i.e.: ensuring that all joints in the pipe system are maintained free of leaks and that any leaks or broken pipes are reported/repaired as soon as possible. Ensuring that community water tanks or domestic rain water tanks have proper fitting lids, be clean, not leaking and free from animals such as frogs, etc.

Report may be:
Verbal in either first language or English

Written correspondence, i.e.: fax, letters, etc.
Photos of the problem/issue
Video recording the problem/issue


Problems that may be outside of the workers area of responsibility include some of the following:

Septic tanks and leach drains that have been installed too close (less than 100m) from the water supply
Low water pressure as a result of inappropriate water system design, or an increase in housing development in the community


Key people or agencies may include:
Community council
Environmental Health Officers

EVIDENCE GUIDE

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 this Training Package.

Critical aspects for assessment and evidence required to demonstrate this competency unit:
The individual being assessed must provide evidence of specified essential knowledge as well as skills
Consistency in performance should consider the workers ability to be able to monitor water supply and water supply systems and check for signs of potential problems
This needs to occur more than once and over a period of time


Access and equity considerations:
All workers in the health industry should be aware of access and equity issues in relation to their own area of work
All workers should develop their ability to work in a culturally diverse environment
In recognition of particular health issues facing Aboriginal and Torres Strait Islander communities, workers should be aware of cultural, historical and current issues impacting on health of Aboriginal and Torres Strait Islander people
Assessors and trainers must take into account relevant access and equity issues, in particular relating to factors impacting on health of Aboriginal and/or Torres Strait Islander clients and communities


Context of and specific resources for assessment:
This unit is best assessed on the job or in a realistic workplace setting
Access to:
a phone and fax when required
tools, materials and equipment for basic repairs and maintenance tasks if necessary
simulation of realistic workplace setting for assessment
