Elements and Performance Criteria

  1. Plan and organise the assessment of household water use.
  2. Gather data on household water use and costs.
  3. Analyse data on household water use, costs and emissions.
  4. Assess opportunities for rainwater harvesting, greywater use and other water conservation measures on the property.
  5. Report outcomes of water use assessment.

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also collect and analyse information on household water use and provide advice on ways to improve water efficiency and conservation in two different residential buildings. The buildings must be drawn from the following classes of buildings under the National Construction Code (NCC): Class 1 buildings, sole occupancy units (SOU) in Class 2 buildings, or Class 4 buildings.

In doing the above, the person must:

assess opportunities for incorporating rainwater harvesting, greywater technologies and other water conservation measures into the residential building

comply with work health and safety (WHS) requirements when conducting the household’s water assessment

apply knowledge of:

trends in household water use and costs

ways of gathering information on household water use and costs

ways to improve household water efficiency.


Knowledge Evidence

commonwealth, state or territory, and local government legislation and regulations impacting on household water use and management relating to:

environment protection

household rainwater harvesting, greywater use and other water conservation and restriction measures

privacy

water restrictions

WHS

government rebates and other assistance programs relating to improving water efficiency in residential buildings

greenhouse gas emissions:

relationship between water use and greenhouse gas emissions

ways of reducing greenhouse gas emissions through improving water efficiency

household internal and external water services

household water use:

non-metered water measurement techniques and tools

trends in household water consumption and factors impacting on those trends

sustainable domestic water use

units of measurement

water bills

water consumption

water restrictions

water tariffs

impact of attitudes, behaviour and preferences of household members on water use

options for improving efficiency of household water use:
