Abstract
A correct modeling of instantaneous water demand can be a powerful tool in the
formulation of an optimal control policy of pressure heads aimed at the
minimisation of physical losses in water distribution networks. The results of an
annual monitoring campaign of instantaneous residential water consumption on
82 single-family residences, whose occupants belong to the same socioeconomic
status, are presented here. The parameters intensity, duration and
frequency of water uses have been estimated, in the hypothesis that the
instantaneous water demand can be described by a Poisson Rectangular Pulse
(PRP) stochastic process. Their temporal and spatial variability has been
analysed considering different temporal and spatial aggregation scales.
