Rainwater project in Charlottenburg: Green oases for Berlin!

Rainwater project in Charlottenburg: Green oases for Berlin!

On June 20, 2025, the district office Charlottenburg-Wilmersdorf and BIM Berliner Immobilienmanagement GmbH signed a pioneering fundamental agreement on rainwater management. This partnership focuses on two neighboring properties: Württembergische Straße 6, which is managed by the BIM, and the Prussian park, which is subject to the district office. The main goal of this project is the storage and use of the rainwater that arises on Württembergische Strasse.

The rainwater collected is saved in a cistern on the property on Württembergische Strasse and transferred to another cistern in the Prussian park via a pressure pipeline. There the water is used to irrigate the public green areas. This initiative is seen in response to the growing challenges related to more frequent and longer dry periods in Berlin, and is intended to help protect the drinking water resources. About a hectare area can be decoupled to relieve the sewage system.

model project for the future

District City Councilor Oliver Schruoffeger emphasizes that the Prussian park is converted into a climate -adapted park. The project is considered a model for future construction and urban development projects, while the BIM managing director Dr. Mathias Hardinghaus emphasizes responsibility for innovative and sustainable solutions. The fundamental agreement thus sets an important milestone for the integrated rainwater management in Berlin.

One of the challenges lies in the legal area of ​​cross -property rainwater use, but the project is professionally supported by the Berlin rainwater agency. The construction start is planned for 2026, which shows that this approach of the sponge city strategy is taken seriously. The concept aims to hold back rainwater on site, to use it sensibly and to have it seep away during extreme weather events.

context of society as a whole

The strategy for climatic adaptation is not only limited to Berlin's projects. According to the Federal Environment Agency, adaptations to climate change must be made in all areas. The progress report on the German adaptation strategy to climate change (this) contains measures and fields of action that also include strategic concepts for rainwater management and urban heat provision.

Leipzig is another example that shows how cities use innovative approaches to cope with climate challenges. Due to deflected areas and decentralized water management systems, urban areas are strategically designed in such a way that they can absorb, store and release water. Similar measures and the promotion of urban biodiversity are also sought in Berlin to increase resilience compared to climate changes.

Overall, the fundamental agreement between the district office and the BIM illustrates the progressive effort for sustainable urban development and improved rainwater management. The combination of natural and technical solutions not only improved the city climate, but also raised the general quality of life of the Berlin population.
