In the sandy lowlands of Brandenburg, a quiet reckoning is unfolding between the ancient logic of water and the urgent logic of industry. Around Baruth and Grünheide, residents watch their gardens wither and their aquifers recede while beverage giants and electric-vehicle factories draw from the same diminishing reserves under contracts written in a wetter era. The crisis is not yet catastrophic, but it is clarifying — forcing a region, and by extension a civilization, to ask who water truly belongs to, and who decides when there is not enough.
Brandenburg's water crisis: Industry expansion threatens region's dwindling groundwater
Residents face water restrictions and garden irrigation challenges; future water scarcity could limit schools and kindergartens; potential displacement or hardship if industrial demands continue unchecked.
If everything is legitimate, why hide it?
Mark
Why does a town of 4,300 people have contracts that give ninety-two percent of its water to two beverage companies?
Mimi
Because those contracts were signed thirty years ago, when the assumptions about water availability were different. The companies needed reliable supply for industrial production. The town needed revenue and jobs. Nobody expected the climate to shift the way it has.
Mark
But couldn't they just update the contracts?
Mimi
That's what residents and researchers are asking. The problem is that the old data still informs current decisions. The authorities say everything is legal and transparent, but they redact the monitoring documents. It's hard to renegotiate when you can't see the full picture.
Mark
What happens if Tesla and Red Bull both expand at the same time the copper mine opens?
Mimi
You have three major industrial operations competing for water in a region that's already struggling to recharge its aquifers. Residents get asked to conserve. Schools don't get built. The river downstream carries less water. It cascades.
Mark
Is there actually a solution?
Mimi
Artificial groundwater recharge could work in some places—storing water from rainy periods for dry ones. But it only works if you have water to store. The real solution is deciding what matters more: industrial growth or water security. Right now, that decision is being made quietly, with redacted documents.
Mark
Who's making that decision?
Mimi
That's the question nobody can answer because the information isn't public. The companies won't comment. The authorities release partial data. The residents are left watching their trees dry out.
El Pulso
- Brandenburg's groundwater has not recovered since the 2018 drought, and rising temperatures are making natural replenishment slower and less reliable with each passing year.
- Red Bull and Rauch hold rights to 92% of Baruth's licensed groundwater extraction — enough to supply 57,000 people — while the town's 4,300 residents receive just 8%, and monitoring documents are handed to the public with large sections blacked out.
- Tesla's Gigafactory already holds a permit for 1.4 million cubic meters annually and is expanding, while schools and kindergartens in the region have been delayed for lack of water — residents face restrictions first because they are the easiest to limit.
- A planned copper mine in Spremberg threatens to discharge saline, sulfurous water into the Spree River, and when lignite pumping ends in 2038, the river could carry 75% less water in dry summers, with consequences stretching all the way to Berlin.
- Researchers and citizen groups are pushing for independent hydrogeological assessments and artificial groundwater recharge as partial remedies, but both require policy decisions that authorities have so far been reluctant to make transparently.
- The underlying question — how to distribute water among residents, agriculture, nature, and industry during prolonged dry periods — is not unique to Brandenburg; it is arriving everywhere as the climate shifts.
In the sandy lowlands of Brandenburg, a quiet reckoning is unfolding between the ancient logic of water and the urgent logic of industry. Around Baruth and Grünheide, residents watch their gardens wither and their aquifers recede while beverage giants and electric-vehicle factories draw from the same diminishing reserves under contracts written in a wetter era. The crisis is not yet catastrophic, but it is clarifying — forcing a region, and by extension a civilization, to ask who water truly belongs to, and who decides when there is not enough.
Petra Liesenfeld notices her garden absorbing less water than it used to. The trees around Baruth, a small town sixty kilometers south of Berlin, are drying out. The landscape is changing in ways that feel both gradual and sudden — the kind of shift you only catch when you stop to look.
Baruth has bottled mineral water since the 1990s. The operation is now controlled by Red Bull and the Austrian company Rauch, who want to expand their facilities. The timing is difficult. Groundwater levels across Brandenburg have been falling for years, and since the severe drought of 2018, the aquifers have not recovered. Ninety-five percent of Brandenburg's drinking water comes from groundwater. The math is becoming hard to ignore.
Of the water the Baruth waterworks are licensed to extract, just eight percent supplies the town's 4,300 residents. The remaining ninety-two percent is reserved for Red Bull and Rauch — enough to serve 57,000 people. The former mayor sees nothing wrong with this; the contracts are legal, and industrial operations simply require more water. But those contracts are thirty years old. Hydrogeologist Irina Engelhardt from Berlin's Technical University argues they rest on outdated assumptions about recharge rates and available volumes. She and a citizens' initiative are demanding independent assessments and real transparency. The authorities have released some monitoring documents, but large sections are redacted. Liesenfeld asks the obvious question: if everything is legitimate, why hide it?
Drought researcher Andreas Marx considers the opacity troubling. Water is a public commodity by law, he says — it cannot be privately owned, and every decision about its use should be open to scrutiny. Germany remains water-rich overall, he notes, but the challenge is managing dry periods that can now stretch two or three years.
The pressure is felt elsewhere. Tesla's Gigafactory in Grünheide holds a permit for 1.4 million cubic meters annually and is planning further expansion, while residents have been repeatedly asked to conserve and local schools have been delayed for lack of water. Marx observes that when resources tighten, residents face restrictions first — they are simply the easiest to limit.
Further south, a large copper mine is planned in Spremberg. Geotechnical engineer Michael Pfeifer warns that water drawn from depths of up to 1,200 meters will be highly saline and sulfurous, and the proposed treatment plant cannot clean it to safe discharge standards. The Spree River, already carrying the legacy of lignite mining, could run seventy-five percent drier in summer once that mining ends in 2038 — with consequences reaching Berlin.
Artificial groundwater recharge — storing wet-season water underground for dry periods — offers partial relief, and Engelhardt is mapping where it could work. But it requires enough available water to begin with. For Marx, the deeper question remains unanswered: when dry periods persist, how should water be shared between residents, agriculture, nature, and industry? It is not a problem unique to Brandenburg. It is a question every region will soon have to face.
Petra Liesenfeld watches her garden struggle. The trees around her hometown of Baruth, a small town sixty kilometers south of Berlin, are drying out faster than they used to. She waters more often now, but the ground seems to drink less. Around her, the landscape is changing in ways that feel both gradual and sudden—the kind of shift that catches you only when you stop to notice it.
Baruth has bottled mineral water since the 1990s. The operation is now controlled by Red Bull and the Austrian beverage company Rauch, who want to build a new canning factory and expand their facilities. The timing is awkward. The region is running dry. Groundwater levels across Brandenburg, the state that surrounds Berlin, have been falling for years. Since the severe drought of 2018, the aquifers have not recovered. Higher temperatures and increased evaporation make it harder for deep soil layers to replenish themselves. Ninety-five percent of Brandenburg's drinking water comes from groundwater. The math is becoming difficult.
The Baruth waterworks hold a license to extract a fixed amount of groundwater each year. Of that total, just eight percent supplies the town's roughly 4,300 residents with drinking water. The remaining ninety-two percent is reserved for Red Bull and Rauch—enough water to serve 57,000 people. How much the companies actually use is not disclosed publicly. Peter Ilk, the town's former mayor and a champion of regional industrialization, sees nothing wrong with this arrangement. The contracts are legal. They prioritize the population's needs, he says, and it makes sense that industrial operations require more water than a small town. The ratio of consumption, he explains, works out to roughly one to ten.
But the contracts are thirty years old. Hydrogeologist Irina Engelhardt from the Technical University in Berlin points out that they rest on outdated assumptions. Groundwater levels have changed. Recharge rates have changed. Land use has changed. The volume authorities believe is available is being overestimated, she argues. Together with a citizens' initiative, Engelhardt is pushing for new, independent assessments and genuine transparency. The authorities have released some groundwater monitoring documents, but large sections are redacted. Liesenfeld asks the obvious question: if everything is legitimate, why hide it? Exactly how much Red Bull and Rauch pay for up to seven million liters of daily extraction remains secret.
Drought researcher Andreas Marx, who heads the Drought Monitor at the Helmholtz Centre for Environmental Research, finds this opacity troubling. Water is a public commodity by law, he says. It cannot be privately owned. Every decision about its use should be open to public scrutiny. Germany and Brandenburg remain water-rich regions overall, Marx notes, but the challenge is learning to manage dry periods that can stretch two or three years. The balance is shifting. Higher temperatures and changing precipitation patterns are making recovery harder.
The pressure intensifies elsewhere in the state. Tesla's Gigafactory in Grünheide, in eastern Brandenburg, holds a permit to extract 1.4 million cubic meters of water annually and is planning to expand production to 7,500 vehicles per week. Meanwhile, residents have been repeatedly asked to conserve. Schools and kindergartens have been delayed because there simply was not enough water. Marx observes that when resources tighten, residents face restrictions first—they are the easiest to limit. Industrial companies rarely do, because the economic consequences are harder to calculate.
Further south, in Spremberg, a large copper mine is planned. Over coming decades, copper—essential for power grids, electric vehicles, and the energy transition—will be extracted from depths up to 1,200 meters. Geotechnical engineer Michael Pfeifer warns that mine water from such depths is highly saline and sulfurous. The proposed treatment plant is not capable of cleaning it to standards safe for discharge into the Spree River, which flows north toward Berlin. The Spree already carries the legacy of decades of lignite mining. When lignite extraction ends in 2038, the groundwater currently pumped into the river from those mines will stop. In dry summers, the Spree could carry seventy-five percent less water, with consequences reaching all the way to Berlin.
One possible answer is artificial groundwater recharge—storing excess water from wet periods underground for later use. Engelhardt is researching where this could work in Brandenburg. In some areas, including where Tesla operates, it could meet nearly all local drinking water demand. But the solution requires enough available water to begin with. For Marx, a deeper question remains: How should water be distributed between residents, agriculture, nature, and industry when dry periods persist? As global temperatures rise, it is not a problem unique to Brandenburg, or even to Germany. It is a question every region will soon face.
