Abstract

Temporal and spatial aggregation in modeling residential water demand R. Guercio, R. Magini & I. Pallavicini Dipartimento di Idraulica, Trasporti e Strade, Universita di Roma 'La Sapienza', Italy 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. 1 The use of instantaneous water demand models in the
