Abstract: In the last few years many mathematical models have been developed for the evaluation of space and time variabilities of water quality parameters in water distribution systems. The differences between these models stem mainly from the flow conditions and phenomena considered and also the nature of the substances examined. Most of these models refer to a steady state condition and the transportation of substances in the pipes is usually considered to be due only to advection while molecular and eddy diffusion tend to be ignored. Furthermore, the substances contained in the water are divided into two classes: conservative and non-conservative For the former, variations in concentration are due exclusively to the mixing, in every node, with the water flows deriving from the pipes flowing into the node itself: whereas the latter are subject to reactions causing their transformation, to decay phenomena and to volatilisation processes in the tanks located along the system.
