The supply of quality potable water to the customers’ branch pipe of the distribution network represents a major responsibility for the water supply system operators. There are circumstances when the quality of the water produced in the water treatment plant is palatable, but the same water distributed to the consumers might be altered (from quality point of view) due to its transport through the distribution network. For that purpose, the present article describes the analysis application to the way the residual chlorine concentration evolution is performed in a regional water distribution network. The numerical model of the distribution network was carried out through the program EPANET 2.0, and the simulation of the network’s performance was performed for a 72 hours period, with the aim at control the residual chlorine concentration in terms of flows passed through. Keywords: chlorine concentration, distribution network, water quality, EPANET.
