Combined Sewer Overflows into the Crati River (Cosenza, Italy) and Retention Storage Sizing
The paper aims to contribute to the CSO pollution mitigation by retention storage, taking into account the observations carried out in an experimental catchment in Cosenza, Italy. A few observed events allowed simple simulation of pollutant buildup and wash-off, serving to obtain average wet-weather flow pollutant concentrations. Consequently, for 23 observed events, volumes, masses and pollutant concentrations in overflows were computed. Assuming five different sizes of retention storage, from 50 to 250 m3/ha, volumes, masses and concentrations of final overflows into the receiving water body were evaluated. A retention capacity in the order of 100–150 m3/ha reduced overflows to 1 to 3 events per the time period studied. The values of pollutant masses and concentrations in overflows, in relation to the flow and ambient water quality in the receiving water (river), should serve to choose the correct storage size.
