Abstract

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 been used to simulate the operation of the tanks. The differences between the performance of on-line and off-line tanks and the influence of the characteristics of different catchments have been examined. According to the results of the simulations detention tanks demonstrated good performances in total suspended solids retention and this evenience can certainly help to prevent water pollution of receiving water bodies in urban areas, even if the differences between the catchments, especially regard to the first flush effect, influence the performance of the tanks. Anyway considerable good efficiencies can be obtained with tank volumes of about 30-50 m 3/haimp, in terms of number, maximum concentrations and duration of overflows, generally not guaranteed only with overflow devices
