The Hanseatic town of Seehausen (Altmark) is planning to create a digital rainwater concept for the urban area. Many stormwater sewers date back to the 1970s and have so far only been incompletely documented. Information on diameter, gradient or flow rates is often missing. Against the backdrop of increasing heavy rainfall events, the performance of the existing drainage system is to be examined more closely in future.
As part of the project, the manholes and pipes are surveyed and the sewers are inspected to record their condition. This is followed by a hydraulic calculation of the network. The aim is to digitally depict the location, size, flow direction and condition of the stormwater sewers. The concept serves as a basis for future renovation measures as well as for heavy rain and flood prevention.
The project is funded through the promotion of measures to adapt to climate change in the state of Saxony-Anhalt (Climate III). The total costs amount to 309,269.10 euros, of which 278,342.19 euros are co-financed by the European Union.
