Abstract: This paper reports some results of an ongoing project conducted in the City of Culiacan, Mexico, to obtain stochastic residential water demand parameters and use them in a large scale hydraulic and water quality network model. Instrument packs were installed on the service lines of 4 homes, and the water demand was monitored with a one-second time resolution for 101 days. The frequency (utilization factor), intensity, and duration statistics of the registered demand pulses were obtained. A Poisson Rectangular Pulse (PRP) model was used to generate water demands for individual homes and for other portions of the distribution network. Three levels of detail in the distribution network were analyzed: all-pipe model, all-pipe model excluding dead-end mains; and sources, tanks and global water demand model.
