Water conflict around the German capital

In the vicinity of Berlin, a growing water conflict has emerged around the German capital. In the small town of Baruth, located roughly 60 kilometers south of the city, residents have observed a decline in groundwater levels over the years. This has led to increased watering of gardens and the drying out of local trees. Two beverage companies, Red Bull and Rauch, are planning to expand their production in the area by constructing a new canning factory and additional facilities.

Currently, the town's waterworks are licensed to extract a limited amount of groundwater each year – around 8% of which is used for the town's roughly 4,300 residents. The remaining 92% is reserved for the beverage companies, enough to meet the drinking water needs of 57,000 people. However, the exact amount of water consumed by the companies is not publicly disclosed, which has raised concerns about transparency.

Hydrogeologist Irina Engelhardt from the Technical University in Berlin believes the contracts, which are around 30 years old, are based on outdated information and may be overestimating the available water volume. She is calling for new, independent assessments and greater transparency. Despite the lack of transparency, Germany and Brandenburg are still considered water-rich regions.

However, the water balance is changing due to factors such as higher temperatures, increasing evaporation, and inadequate groundwater recharge. The drought researcher Andreas Marx emphasizes that water is a public commodity and advocates for open communication regarding decisions and contracts related to its use. Meanwhile, Tesla's Gigafactory in Grünheide, which is planning to expand production, faces restrictions on water extraction to ensure sufficient supply for residents.

Further south, a planned large mine in Spremberg could exacerbate the water situation, as the extracted mine water is highly saline and sulfurous, requiring extensive treatment. The proposed treatment plant is insufficient for this task. Artificial groundwater recharge, where excess water from periods of high rainfall is stored underground for later use, is being researched as a potential solution to the water problems facing the region.
