To assess water savings in households using efficient devices and to understand how savings vary between different socio-demographic groups in the community, high resolution end use water consumption data is required (i.e. disaggregating water use for showers, toilets, clothes washers and garden irrigation etc.). This paper reports selected findings from the Gold Coast Residential End Use Study (Australia), which focussed on the relationship between a range of socio-demographic and household stock efficiency variables and water end use consumption levels.
