Open day: Böblingen invests millions in clean water!

Last Sunday, June 30, 2025, the Böblingen-Sindelfingen sewage treatment plant opened its doors to interested citizens. In bright sunshine and summer temperatures around 30 degrees, visitors were able to take a look behind the scenes of wastewater treatment. They found out about the fascinating path of the wastewater through rotten towers, dripping bodies and promotion basins. Such events are not only informative, but also promote awareness of the valuable process of water treatment, which plays a central role in our region. The stuttgart news reported on the exciting insights that were offered to visitors.

It is particularly noteworthy that the operators of the Böblingen-Sindelfingen sewage treatment plant are planning one of the largest investments in the history of the system. The wastewater treatment plant, which has been operated together by Böblingen and Sindelfingen for over 60 years, reacts to the increasing demands on wastewater treatment and the increasing importance of environmental protection. The merger, which began on April 19, 1959, shows how important the sustainable handling of water is for the quality of life in the region. The Zweckverband Klärchage emphasizes that the sewage treatment plants in Böblingen-Sindelfingen and Dagersheim-Darmsheim are not only modern, but also sustainable.

sustainability and technological progress

In recent years, the sewage treatment plants have been further developed beyond the legal requirements. Always greater technical progress have revolutionized the type of wastewater treatment. In 2011, for example, with the support of the EU, a fourth cleaning level was introduced, which enables trace substances such as drug residues, hormones and industrial emissions from the waste water. Microplastics can now also be filtered for the most part. This is an important step to lead our water sustainably and environmentally friendly to the swippe. According to the special-purpose association , a system is also set up at the Dagersheim-Darmsheim location.

But why is all important? Water and wastewater management are crucial for quality of life and environmental protection. The increase in water shortages and environmental pollution increases the need to use modern technologies and to promote sustainable water management. The Fraunhofer institute calls adapted technologies as well as the reuse and recycling of water resources as essential for the future. The key to success lies in the integration of environmentally friendly practices in the water and sewage circuit.

In conclusion, it is important to thank the employees of the sewage treatment plant for their excellent work. They make a significant contribution to protecting the waters and improving the quality of life in the region. Her committed work ensures that the water supply and cleaning will continue to meet the highest demands in the future.
