How efficient are stormwater control measures for micropollutant management? Feedback from Matriochkas, MicroMégas and Roulépur projects

Abstract : The pooling of results from three French projects (Matriochkas, MicroMégas and Roulépur), within the framework of a working group on methodological harmonisation, makes it possible to analyse the performance of a wide range of stormwater control measures (SCMs) in terms of micropollutant load reduction. Data covers 12 management systems, in 9 different urban contexts. The results highlight the diversity of runoff contamination levels and of their distribution between dissolved and particulate phases. They show significant reductions in particulate pollutants for all filtration-based systems, and less for those that only allow sedimentation. Performance is more limited for the dissolved phase, for which concentration reduction is limited and significant load reductions are only achieved due to a reduction in runoff volumes in structures promoting evapotranspiration.
