There has been a sewage treatment plant at Wassmannsdorf for around 130 years. The plant at Schönefeld in Brandenburg keeps clean water flowing for the citizens of Berlin and the surrounding areas while also helping to protect the environment. By 2024, the capacity of the plant will be expanded to 2.1 million citizens. Alongside additional purification stages, the plant will gain a new mixed water tank with a capacity of 50,000 m³. A powerful water treatment solution for decades to come.
The Wassmannsdorf project is currently the largest and most comprehensive ongoing project in the portfolio of the Berlin water authority. The operator is investing around 275 million euros in future-proofing the sewage treatment plant. The commissioning process will take place in stages between 2019 and 2024.
High-level water treatment: Wassmannsdorf sewage treatment plant is to be expanded in two phases by 2024. The expansion will enable the plant to handle water treatment for up to 2.1 million citizens based on the latest technology and biological developments, creating the ideal conditions to secure a long-term, high-output water supply for the residents of Berlin and the surrounding areas — with environmental protection in mind at all times.


The expansion of the Wassmannsdorf sewage treatment plant is an exciting but complex project that aims to deliver cutting-edge public utility services.
