A method for regulating the residual free chlorine in drinking water, characterized in that the regulation is carried out by introduction of a quantity of chlorine determined as a function of the chlorine demand at 'the head' of the line, that is upstream of the water treatment or storage line, while obtaining in the distribution network, water having an acceptable residual free chlorine content. The chlorine demand of the water at the inlet of the treatment, or storage line is rapidly determined by accelerating, the reactions tied to disinfection by heating so as to obtain over a short period (from 5 to 10 minutes) water having a residual free chlorine content corresponding to the required value.
