The mere fact that in the Earth every second person is an urban citizen brings along serious water management consequences and the handling of them requires non-traditional professional knowledge, methods and principles. In an urban area the natural watershed lines have been basically changed by man made intrusion and this resulted in basic changes in the qualitative and quantitative properties of the water, that is of the hydrological cycle. Runoff and the peak flow were drastically increased in comparison to the natural ones of the given site, while the time of concentration and the time to peaking were reduced (Figure 1). Along the surface runoff route the water receives pollutant inputs from the construction sites, from transportation and traffic from the littering and from many other sources. This pollutant washoff is especially high after longer dry periods. To this pollution comes the scouring
