SewerNetOpt

Within urban development areas domestic and trade wastewater as well as extensive quantities of rainwater dependent on the percentage of impermeability accrue. Since the middle of the 1970s real-time control has been applied to manage systematically existing drainage assets and thus to utilise the maximum of the systems capacities. The development of the integrated control of sewer network and wastewater treatment plant has been furthered in the last decade. However, the operational application on large and complex systems is still rare. Due to that reason, the research project EVA is carried out in Berlin aiming at the implementation of a decision support system for the global control of sewage pump stations. SewerNetOpt is a subproject within the joint project EVA.

Goal of the subproject is the derivation of strategies for the control and dynamic distribution of wastewater to different treatment plants during rain. Definition of the control strategies is carried out by mathematical optimisation based upon an algebraic modelling system.
