Abstract An urban water demand model at a water supply distribution zone level is developed. The model is based on a previous proposition that water use is made up of base use determined from winter consumption and as a function of day of the week, rainfall and temperature and of seasonal use assumed to be composed of the potential use that is dependent on temperature in the absence of rainfall, and of the short effects of climatic factors. Daily data of East Doncaster zone from April 1991 to December 1999 are used in the regression model and is evaluated based on R2 and standard error. The model is tested independently using data collected from 2000-2001.
