Integrated wastewater management

The “Integrated Wastewater Management” (ISM) project was conducted in order to develop a model for integrated control for the Berlin wastewater system. The aim was to evaluate a planned wastewater pumping station and mixed water measures.

Through the use of this arithmetic model for the Berlin wastewater pipe grid which was developed from 2000 between Veolia and Berliner Wasserbetriebe and from 2003 within the Kompetenzzentrum Wasser Berlin gGmbH, we were able to carry out emission-oriented investigations into the control potential of the wastewater pumping stations in the catchment area of the Schönerlinde wastewater treatment plant. The aim of these investigations was to evaluate the planning of the construction of a new wastewater pumping station in the radial system with respect to its control potential; it was thereby discovered that additional pumping capacities are not necessary.

Furthermore, a study for expansion of the criteria catalogue for the evaluation of measures for mixed water treatment was elaborated and the order was placed in 2006. The evaluation will in future take into consideration the ecological state of the lakes and rivers on the basis of immission-oriented, location-specific criteria. The water-specific demands, allowing for a practice-oriented application of the water quality models employed in Berlin and the ISM model are used to derive the criteria.
