Urban surface water run-off may generate considerable pollution loads to watercourses in certain types of basins. Stormwater run-off dissolves and picks up materials forming urban surfaces (roads, roof tiles, etc.) or that are deposited on the same, and carries these to the drainage networks and potentially to water bodies. The problem presented in...

The urban runoff contains a significant amount of pollutants. Due to CSO limitations and WWTP’s biological processes, wastewater discharge must be regulated not only in quantity but also in quality.
