Refurbishment of the Zöbingen sewage treatment plant: City council is making pioneering decision!

In the municipal council of Unterschneidheim, important decisions were recently made to renovate the Zöbingen sewage treatment plant. This facility, which dates from the 1970s, is urgently needed. Mayor Johannes Joas reported that an application for an 80 percent state subsidy should be made. A previous application for the construction work was rejected in September 2023. The estimated costs for the renovation amount to 5.415 million euros.

The plans include the construction of a new clarification basin, the implementation of a phosphate falling, a mechanical pre -cleaning and the construction of a new company building. Udo Bäuerle from the B&P office explained the technical details of these measures, which are to be realized from 2026 to 2028.

criticism and discussion

Anton Joas expressed concerns about the increase in costs, which was originally valued at two million euros, instead called for the construction of a central sewage treatment plant to avoid increasing wastewater fees. This is supported by Michael Schimmle, Vitus Thorwart and Steffen Joas, who spoke out for the existing wastewater concept. Udo Bäuerle noted that the increase in costs was due to the increased construction prices and that a new building would be associated with higher costs.

The possibility of an 80 percent state subsidy was emphasized by Johannes Hammele as an advantage. Nevertheless, there was a vote against Anton Joas when the municipal council finally decided to submit the application for the grant as soon as possible.

decentralized wastewater disposal as a future model

In parallel to the discussions about the sewage treatment plant, the concept of decentralized wastewater disposal is becoming increasingly important. According to dau GmbH , the conventional central wastewater treatment shows a significant need for changes. Central systems are often costly and environmentally harmful, while decentralized alternatives, such as small sewage systems, clean sewage directly at the generation location.

These decentralized systems offer numerous advantages: they are inexpensive and economical, reduce high investment costs and avoid additional operating and maintenance costs. Many municipalities and companies are now relying on these sustainable solutions. However, regular maintenance and professional know-how are necessary to operate the systems efficiently and to receive approval by the authorities.

The discussion about the renovation of the Zöbingen sewage treatment plant shows that both traditional and new approaches to remove wastewater must be carefully weighed. iwu provides further information about the legal and technical aspects of the decentralized sewage disposal, which could be important for future planning.
