Increase in costs for water and waste water confirmed
In 2025, residents of Baden-Württemberg saw an increase in their water and sewage fees. The rates have been on the rise, outpacing general inflation, due to various factors such as infrastructure investment, enhanced wastewater treatment requirements, and climate-related impacts.
The increase in water fees was approximately 9%, while sewage fees saw a rise of around 5%. This marks a slight acceleration of the trend observed in previous years, where rising costs reflect the need to maintain and upgrade water infrastructure amid environmental challenges.
One key contributing factor to the fee increase is the investment in sustainable and resilient infrastructure. Financial frameworks, such as that of LBBW, emphasise the importance of sustainable water and sewerage operations to comply with evolving environmental standards.
The impact of extreme weather events, like heavy rains and storms, has also played a role. These events have caused sewer overflows and infrastructure strain, as seen in the July 2025 train derailment linked to an overflowing sewer that triggered a landslide. Such events necessitate costly emergency responses and system upgrades to handle climate volatility.
Technological and environmental advancements, such as decentralized waste-to-hydrogen plants, are planned for Baden-Württemberg in 2025. While promising sustainability gains, these innovations can contribute to higher fees due to implementation and operation costs.
Advanced water treatment measurement and technology to combat issues like legionella and maintain water softness also add operational expenses.
It's worth noting that the increase in water and sewage fees was lower than in some previous years. However, the increases still outpaced the inflation rate of 2.3%. On average, sewage in Baden-Württemberg now costs 2.36 euros per cubic meter, and a cubic meter of water now costs 2.72 euros.
Unfortunately, no specific information about the change in fees for individual cities or municipalities was provided. The increase in fees is primarily due to higher energy and construction costs, as well as investments in climate-resilient infrastructure.

The financial framework of LBBW highlights the importance of investing in sustainable water and sewage operations, which is one of the key contributing factors to the rise in fees. In the face of environmental standards and challenges, this investment allows for the maintenance and upgrade of water infrastructure.
Despite the rise in fees, advanced water treatment technologies are planned for implementation in Baden-Württemberg in 2025. These technologies, while offering sustainability benefits, will likely contribute to higher fees due to their implementation and operation costs.
