In this study, a total of 22 storms was surveyed in two separated sewer systems in the town of Luxembourg during the period from August 2003 to February 2004. For each storm event, both runoff and quality parameters were analysed. Inter-storm and intra-storm variability were determined for both sewers, and the relationships between Event Mean Concentrations (EMC) and runoff patterns analysed. The magnitude of the first flush effect was calculated through the dimensionless curves representing the variation of the cumulative pollutant mass ratio in relation to the cumulative volume ratio. The presence of illicit sanitary inputs in one of the sewers produces a significant first flush effect in its storm runoff as well as higher EMC for all the pollutants related to suspended solids.
