While it is possible to calculate water use over a fairly short period of time, this only yields a single value for peak use. It does not give a comprehensive understanding of the frequency, duration and magnitude of these events. These additional characteristics of peak demands are investigated. In addition to determining the characteristics of peak use periods in the system, the study also developed diurnal demand curves which explain water use as a function of time of day. These demand curves can be used as input to an extended period simulation model of a water distribution network, the results of which can be used in pipe, pump and tank sizing.
