Hydraulic testing of the renovation work on a rainwater basin and the construction of a new drop shaft using a 3D-CFD simulation.

Upper figure: Deflection of the dry weather runoff into the pipe to the sewage treatment plant. Lower figure: Filling process of the rainwater basin during rainy weather. The water surface is shown with the flow velocities.
