Abstract: Climate change and the associated intensification of the hydrological cycle pose ever greater challenges to our cities. At the core, this almost always concerns the infrastructure, especially that which lies beneath our streets. This often dates back to the middle of the last century and is not designed to meet constantly changing challenges. On the one hand, drainage systems are often unable to fully absorb runoff from heavy rainfall events, which can lead to flooding; on the other hand, falling groundwater levels during long dry periods lead to bottlenecks in the drinking water supply. As the Resource: Mannheim project shows, water-sensitive urban development can not only make an important contribution to the sustainable handling of more extreme climatic conditions and the relief of the infrastructure, but can also lead to a higher quality of life and stay through the creation of pleasant recreational space and effective microclimate regulation. This contribution shows the results of microclimate and hydraulic sewer system relief modelling of a cascaded grey water and stormwater runoff reuse system integrated in a residential open space.
