The demands on urban water networks are constantly growing due to increasing populations, urbanization, and changing climate conditions, where the current climate crisis also leads to more and more extreme weather events. In Berlin, peaks in the load currently require the utilities to relieve about seven billion liters of combined wastewater into the surface waters of the city each year. These combined sewage overflow events lead to an acute surface water pollution and massive fish death. Yet, an expansion of the 150 years old underground sewers would be extremely expensive, if not entirely impossible. Therefore, ways need to be found to maximize the utilization of the existing infrastructure.
The joint project “OPTIMA” aims to develop a predictive control system for wastewater pumps that anticipates heavy loads. Data from various sources will be used to predict loads in the sewage system. These predictions will allow to optimize the use of the existing retention room of wastewater networks. This way, both damaging backwater and combined sewage overflow events are to be reduced.
The project is funded by the ProFIT program of IBB/ILB and a collaborative effort between partners in Berlin and Brandenburg.
