The main challenge in Gliwice is the management of combined sewer overflows and how to better predict and control them. The combined sewer system was designed in the beginning of the previous century and has problems dealing with the more frequent and heavy rainfall events in the highly urbanised city. The rainwater, treated wastewater and combined sewer overflows all end up in the Klodnica river that runs through the city centre. The first step in the solution to the problem is to assess the frequency of combines sewer overflows and their impact on the receiving water. The demonstration in Gliwice will deal with enhanced real time measuring and forecasting technologies for combined sewer overflows in the central historical part of the city, with the aim to better control and safeguard the water quality in the river.
