A practical application of integrated urban pollution modelling in Flanders (Belgium): the catchment of Tielt.

In view of a European Innovation Project (DG XIII) on the application of the Urban Pollution Management (UPM) procedure, a European consortium was set up to carry out pilot studies in Belgium, France, Ireland, Italy and Portugal. On the Belgian pilot catchment of Tielt the impact from sewer system and sewage treatment plant (STP) on the receiving water courses was studied for both the existing situation and for a number of possible improvement schemes, using the Intermittent Standards, described in the UPM procedure. The integrated modelling revealed some interesting conclusions on the relative impact of the schemes considered.
