A mathematical model able to evaluate water quality variations in complex hydraulic pressure systems has been developed. The model consists of a set of mass balance equations for tanks, pipes and nodes. It has been applied to predict chlorine concentration inside a case-study water network described in literature by using different expressions of chlorine decay coefficients, obtained in laboratory tests and expressed as a function of the residence time of water in pipes, the initial chlorine concentration, the history and temperature of water. The results showed little variations of the chlorine concentrations and the need to calibrate the parameters of chlorine decay coefficients expressions on full scale hydraulic systems.
