In combined sewer systems suitable reaches are selected where overflow devices are located so that only a certain fraction of the maximum discharge is allowed to continue towards the treatment station. Over the last decades two storm sewage overflows have been favoured: bottom openings and side weirs.

Abstract
In combined sewer systems suitable reaches are selected where overflow devices are located so that only a certain fraction of the maximum discharge is allowed to continue towards the treatment station. Over the last decades two storm sewage overflows have been favoured: bottom openings and side weirs. Although several studies have been made on these structures, currently there are still gaps in the knowledge of their working. In this paper, both theoretical and experimental analysis, addressed to a better understanding of the hydraulic features of these devices, are presented. Guidelines for their design are also given.File in questo prodotto:
