The advantages of applying a stochastic residential water demand scheme in a distribution network water quality model are presented. Two water quality models were implemented on a real water distribution network in which chlorine concentration tests were carried out. In the first one the water demand was represented by synthetic stochastic series generated by the Neyman-Scott Rectangular Pulse Method and in the second a deterministic Hourly Demand Variation Curve was employed. Compared to field-measured data, the first model presented differences with an average of 23%, and the second one differences with an average of 67%. © 2013 The Authors.
