One of the most effectiveness solution for the control of pollution in river caused by combined sewer overflows (CSOs) is to introduce storages in sewer system in order to retain a part of the storm waters. This paper refers about the analysis of quali-quantitative control of emissions from overflows by means of tanks designed using historical rainfall series and genetic algorithms. The tanks are also equipped with mobile gates, real time controlled with a fuzzy logic approach. The work can be summarized in three phases. The first, consisted of defining the problem and, in particular, the set of rules applied to the control. In the second the system was subjected to a historical rainfall series and assessed by means of an appropriate objective function. A genetic algorithm was used to define the most appropriate management logic and the minimum volume to assign to the tanks. In the third phase, of validation, the optimized model was checked on the basis of another historical rainfall series. This work is characterized by a real time control based, not only on water level, but also on pollutants concentration. The results lead to tanks with a mean volume of about 30 m3/haimp for the virtual sewer network analyzed.
