Popis: Residential water consumption reductions resulting from water efficiency measures has received much research attention in recent years; however, research into the contribution of such measures in reducing hourly water demand and subsequent benefits to urban water service infrastructure efficiency is still in its infancy. In an attempt to address this issue, this study examined the degree of influence that differing water stock (e.g. taps, shower heads, clothes washers) efficiency in 191 households, participating in an Australian smart metering study, had on average day (AD) diurnal consumption patterns. Sub-sample clusters used for analysis were formed by a weighted household water stock efficiency star rating classification method. Results showed a statistically significant reduction in AD peak hour water consumption in households with stock of a higher composite star rating. Paired comparison between households with a composite efficiency rating greater than or equal to (≥) three stars and those of a composite rating less than (
