The objective of this study is to develop new operational management practices for detention basins during rainfall events in order to limit flooding risk and, at the same time, to reduce pollutant discharges by optimising the settling process. For this work, a methodology was developed to study the integration of the stormwater treatment into existing detention structures. In this article, it was applied on two experimental sites. The current operation of the basins and “on/off” regulation studies were first carried out to quantify the freedom to act to change the control schemes. Relying on the support of these studies, new operational rules based on the current or “on/off” principle were then elaborated and tested on the experimental basins using a hydraulic model. Finally, their efficiency to protect against flooding and to reduce pollutant discharges was assessed.
