Abstract: In an urban water supply network, the chlorine is used as a disinfectant. Its absence involves the risk of microbial contamination which can degrade the quality of water. According to the standards of World Health Organization, the residual chlorine content in water shouldn’t be lower than 0.25 mg/l. Chlorine reacts with many compounds and thus undergoes degradation throughout its transit in the conduct of the network. This degradation is the result of several physical factors (age of conduct, matter, flow, speed…) and bacteriological (germs, coliform, biofilm…). In this paper, we use a mathematical model for mapping the degradation of the Chlorine along the water supply network. The concentration of chlorine in each control is also performed. We used an algorithm of Hierarchical Classification taking into account some characteristics (nature of conduct, speed, flow). Results shows that degradation of Chlorine calculated matched well with the measured one. This model allowed us to have a real-time data about the Chlorine content and thus to overcome the problem of the measure of the chlorine due to the non accessibility of the conducts.
