| Short description: |
The infiltration of groundwater into sewer systems reduces the efficiency of the sewer
networks and may thereby result in a deterioration of receiving water quality. Besides
these widely known impacts of parasite water sewers are serving as drainage
systems during wet-weather periods and flood events and could diminish problems of
increasing groundwater levels. The “efficiency” of this drainage effect is evaluated in
the city of Dresden. The investigations deal with the effects of the Dresden sewer
system during and after the flood event in August 2002, when the groundwater level
rose to a maximum level since data were recorded. To estimate and predict the
drainage effect the hydrological leakage model is calibrated and used. Furthermore,
the leakage of sewers has been assessed.
