    Australian Bureau of Statistics (ABS)

    The Domestic Use of Water and Energy Survey was conducted in Western Australia (WA) in October 2006 as a supplement to the Monthly Population Survey. It presents information on water and energy usage and appliances. Data items include the type and use of heaters and cooling units, use of bores and rainwater tanks, type of hot water system used, type of water using appliances (e.g. washing machine, dishwashers, toilets, showers, baths), details of garden watering systems, whether the household has a pool and/or spa and if so, whether it has a cover and/or is heated and whether the dwelling has an electrical safety switch.

    The Water Corporation requested a repeat of the 2003 Domestic Water Use state supplementary survey to:

    • assess the number of households that have Waterwise products and if households have adopted Waterwise behaviour;
    • assist in their review of the Waterwise rebate scheme in 2007; and
    • forecast water demand based on more current data.

    The Office of Energy, incorporating the Sustainable Energy Development Office and the Electricity Reform Implementation Unit require data to:
    • assist in the development of initiatives in relation to demand management; and
    • gain a picture of the energy efficiency features of WA dwellings e.g. type of dwelling construction, insulation and availability of fuels.

    The Department of Consumer and Employment Protection - Energy Safety Division require data to:
    • understand the extent of household use of unflued gas heaters in response to recent health concerns raised over the use of these appliances; and
    • assist in the development of regulatory and educational programs to increase the safety of Western Australians in their homes.

    Western Power require data to:
    • assist in planning for pressure placed on electricity supplies by increased air conditioner usage and avert another crisis as experienced in WA in February of 2004 with a day of power blackouts.

    Department of Environment require data to:
    • assess the impact of the department's current education programs (Waste Wise and Waterwatch); and
    • assist policy decisions involved in promoting the sustainable use of water and energy.

    Department of Housing and Works require data to:
    • assist in assessing water and energy efficiency strategies for current WA housing constructions;
    • monitor the preference of group housing and how it relates to water and energy efficiencies in dwellings; and
    • assess the types of appliances currently in public housing, in particular gas versus electric.

    The DUWE survey was conducted as a supplement to the ABS Monthly Population Survey (MPS) in October 2006. It was conducted on a subset of the full sample of private dwellings in WA that were included in the MPS. It covered all persons who were usual residents of private dwellings except:
      • members of the Australian permanent defence forces;
      • certain diplomatic personnel of overseas governments, customarily excluded from censuses and surveys;
      • overseas residents in Australia;
      • members on non-Australian defence forces (and their dependents) stationed in Australia; and
      • persons living in sparsely settled areas of WA.

    Coverage rules were applied to ensure that each person was associated with only one dwelling, and hence had only one chance of selection in the survey.
