Residential Water Use in New Zealand Homes

The study brings together survey and high-resolution water meter data collated by BRANZ and analysed by BRANZ and the University of Auckland. The results of this study provide information on seasonal and diurnal peaks, water end use, average dwelling and residential water use and minimum night flows. These results are valuable for applications such as infrastructure sizing, water efficiency programme design, and water demand forecasting.

Join Dr Colin Whittaker of University of Auckland and Building Physicist Andrew Pollard of BRANZ for a summary of the report and their findings.

This project has been funded by BRANZ, The Water Services Managers Group and Wellington Water, with the support of 29 Councils.
