Resumen:
Residential water demand behavior is one of the variables with highest uncertainty in the hydraulic analysis of water distribution networks. It has been recently shown that water demand at residential level has a stochastic character and different methodologies have been developed trying to represent its variation. There are two outstanding methods to represent the high variability of residential demand within water distribution systems: Poisson Rectangular Pulse (PRP) method and Neyman-Scott's Rectangular Pulses (NSRPM) method. Each of them offers advantages and disadvantages in the generation of systematic water demand series. The PRP supports its theory on measurements with one second registry interval, and on the other hand NSRPM can generate time series with different registry intervals which allows to carry out temporal aggregation and disaggregation processes. Based on Fourier analysis, this paper develops and implements a tool for disaggregation of water demand series and gets the optimal recording interval. © 2010 Taylor & Francis Group, London.
