The impulse project serves to demonstrate blue-green solutions as a concrete option for the Stuttgart Rosenstein quarter to be developed. Innovative storage and treatment options and green systems integrated into the design of the site show that even in inner-city neighborhoods, measures of integrated blue-green planning can be successful in a confined space. The entire project was developed through a transdisciplinary process to align water availability and demand.

In the direct vicinity of temporary worker housing for the Stuttgart 21 infrastructure project, the graywater produced in the showers and hand-washing sinks is treated by a constructed wetland and used in conjunction with rainwater to irrigate green facades on the housing containers.

The temporary shelters are particularly well suited for greywater use: the installation is easily accessible, and there is little need for complex and expensive interventions in the building structure or for earthworks.

The pilot project is part of the research project Integrated Strategies for Strengthening Urban Blue-Green Infrastructures (INTERESS-I), which is developing concepts and measures for improving settlement and building structures based on urban climate requirements, water availability and quality, and open space concerns.
