Context

In settlement areas domestic and industrial waste water as well as, depending on the surface impermeability, significant quantities of rain water accrue. Since the middle of the seventies real time control of urban drainage systems has been applied chiefly in the USA, later on in Europe too. The objective is to manage systematically existing drainage facilities and thus to utilize the capacity of the formerly static system as extensively as possible. The development of integrated control of sewage network and waste water treatment plants has progressed during the last 10 years. Nevertheless, an operational implementation of the concepts for huge, complex systems has hardly been realized. This was an obvious reason to initiate the project "Integrated Sewage Management" in Berlin.

Objectives

The ISM project aims at the development of strategies for the integrated management, as well as the initialization of decision support tools for the planning and the operation of the Berlin sewage system. Eventually, the implementation of local controls and an integrated global control of the system is sought.
By integrating the subcatchment model into the operational decision-making process an optimized utilization of storage- and treatment-capacities of the overall system shall be achieved. Thereby a reduction of the impact on watercourses will be effected.

Implementation

The project is divided into 4 main phases. Each of these phases consists of one or more specific studies:

  • Technical analysis of available methods and models for the integrated mapping and simulation of sewage systems. Review and analysis of the Berlin drainage system including the subsystems sewage networks, pressurized network and waste water treatment plants and the corresponding interfaces.
  • Analysis and evaluation of different models for the simulation of sewerage and treatment processes. Realization of comparative calculations for two catchment areas in Berlin-Köpenick (Germany) and Grand Couronne (France) and evaluation on the basis of measurements.
  • Examination and evaluation of the control potential of the Berlin drainage system. Application of combined methods for the development of management strategies and decision support tools for the planning and the operation of a subsystem of Berlin (subcatchment wwtp Ruhleben).
  • Definition of methods for the urban Berlin watercourses that allow for evaluating measures of combined water treatment on the basis of immission criteria.

Phases I to III have been conducted from the end of the year 2000 to the year 2002 by the companies Veolia Water (formerly Vivendi Water) and Berliner Wasserbetriebe within the framework of a preliminary project. From the year 2003 on the project is incorporated into the Kompetenzzentrum Wasser Berlin. The project is funded by Veolia Water and Berliner Wasserbetriebe.
