End use water consumption in households: impact of socio-demographic factors and efficient devices

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 irr...

Description
Summary: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. A mixed methods approach was executed using qualitative and quantitative data. The study provided evidence as to the potential savings derived from efficient appliances as well as socio-demographic clusters having higher water consumption across end uses. The payback period for some water efficient devices was also explored. The study has implications for urban water demand management planning and forecasting. [Display omitted] ► Household water consumption compared in four suburbs of the Gold Coast, Australia. ► Main water uses are showers, clothes washers, faucet, toilets, irrigation. ► Paper tests influence of installing efficient devices and socio-demographic factors. ► Higher status group irrigates more; lower status groups use more in bath and shower. ► Savings from efficient shower 11.3 kL/person/yr; efficient clothes washer 14 kL/person/yr.
