Rise in Water and Sewage Costs Continues
In Baden-Württemberg, the average cost of one cubic meter of sewage now stands at 2.36 euros, while the cost of one cubic meter of water is 2.72 euros on average [1]. These fees are set by the State Statistical Office, similar to water fees, and have increased at the start of 2025.
The increase in sewage fees is around 5%, higher than the inflation rate of +2.3%, but lower than the increase in water fees, which is approximately 9% [1]. The higher energy and construction costs, as well as investments in climate-resilient infrastructure, contribute to the increase in both sewage and water fees [2].
One of the main reasons for the significant increase in these fees is the addition of advanced treatment stages in wastewater plants. For instance, the Bickenbach wastewater treatment plant has added a fourth treatment stage beyond the customary three, enhancing the purification process but also raising operational costs, which are passed on as increased fees [1].
These wastewater treatment advancements align with efforts to meet higher environmental and sustainability standards in the region, requiring more complex and costly infrastructure [1][2]. Innovations in related environmental technology, such as decentralized waste-to-hydrogen platforms launching in Baden-Württemberg in 2025, reflect a broader context of investment in sustainable utilities and infrastructure, which often leads to increased operational costs reflected in consumer fees [5].
It's important to note that the exact increase compared to inflation and the previous year is not provided in the available information. However, this investment in advanced purification technology, alongside broader sustainability and environmental protection measures, is indicative of cost rises above normal inflation trends.
The fees for sewage and water are both set by the State Statistical Office, not by local authorities. The increase in both fees is a result of the same factors contributing to the increase in water fees: higher energy and construction costs, as well as investments in climate-resilient infrastructure.

The advancements in environmental science within wastewater treatment plants, such as the addition of extra treatment stages, are driving up sewage fees in alignment with industry standards. These increased costs in the environmental-science sector, due to investments in climate-resilient infrastructure, are also reflected in the rise of water fees, much like finance trends.
