Understanding the Effect of Household Rainwater Tanks on Hourly Residential Water Use
A lack of understanding surrounding the interaction between residential water use and household rainwater tanks (RWT) restricts the ability to assess the performance of these systems accurately. To improve the understanding and facilitate the inclusion of RWT in future sustainable water planning and water supply system design, this study examined hourly mains water use data from 100 households, half with RWT in the eastern suburbs of Melbourne, Australia, between 2010 and 2012. Average diurnal patterns of residential water use for households with garden watering and without for each season were developed and compared. The analysis revealed that the introduction of RWT resulted in an average overall reduction in daily water use of 3.1%. The diurnal patterns showed that the maximum hourly water use shifted to the morning peak and increased the maximum hourly demand factor by 12%–26% depending on season, with increases in the peak hour factor of 50% in some property subcategories. The analysis also suggested that the introduction of RWT had a greater effect on outdoor water use at these households than on indoor water use (even on properties without garden watering). While the analysis was preliminary and requires further studies, the results would benefit water authorities and water resource planners in future designs of water supply systems and water conservation measures.
