This paper points out that the ideal chlorine concentration range to be maintained within distribution systems is very narrow and could be centered on a value of 0.1 mg/L. Due to chlorine consumption, the maintenance of this residual throughout the distribution system is very difficult. To reach this objective, it is necessary to reduce the main parameters responsible for the chlorine consumption (organic matter, chlorine demand, corrosion) and to implement the tools which allow a real management of chlorine residuals such as water quality modeling, on line monitoring and rechlorination booster station.
