The design of water and wastewater supply systems is traditionally based on maximum water demand which is a function of multiple factors. Understanding these factors and how these affect maximum water demand will lead to the estimation of appropriate peak design factors for a more cost effective design of water and wastewater supply systems. This paper describes the maximum water demand of four separate residential suburbs in Greater Melbourne, Australia with populations ranging from 1000 to 20,774. The study involves the analysis of water consumption data recorded at five-minute intervals over one year. The effects of population and the sampling interval on the peak factor have been analysed. From a set of data collected at five-minute intervals, further data sets at 10, 20, 30 and 60 minutes have been derived. New equations to estimate the peak flow demand for a small number of the population have been developed. Results also show that at five-minute intervals, a more accurate peak design factor has been estimated.
