The performance of detention tanks with different characteristics (volume, on-line and off-line arrangement) has been evaluated according to the results of a continuous simulation.The conceptual simpliﬁed model for sewer system simulation (COSMOSS) model has beenused to simulate the operation of the tanks.The differences between the performance of on-line and off-line tanks and theinﬂuence of the characteristics of different catchments have been examined.According to the results of the simulations detention tanks demonstrated goodperformances in total suspended solids retention and this evenience can certainly helpto prevent water pollution of receiving water bodies in urban areas, even if the differencesbetween the catchments, especially regard to the ﬁrst ﬂush effect, inﬂuence theperformance of the tanks. Anyway considerable good efﬁciencies can be obtained withtank volumes of about 30–50m3/haimp, in terms of number, maximum concentrations andduration of overﬂows, generally not guaranteed only with overﬂow devices.
