| Short description: |
An adequate understanding of the hydraulic interaction between leaky sewers and
groundwater is essential for the sustainable management of both sewer systems and
aquifers in urbanized areas. Undesirable infiltration of groundwater into sewers can
contribute over 50% of the total discharge and is detrimental to treatment plant effi-
ciency. On the other hand, in many European cities groundwater surface levels seem
to be particularly controlled by the drainage effect of permeable sewer systems. However,
nowadays methods for the quantification of these exchange processes are still
subject to considerable uncertainties due to their underlying assumptions. The frequently
used assumption that the night time minimum in the diurnal wastewater hydrograph
is equal to the 'parasitic discharge' has to be reconsidered to today’s patterns
of human life as well as to the long residence time of wastewater in the sewer networks
of modern cities.
