Wetland Restoration Is Being Used to Recharge Groundwater

Amazon and Microsoft are funding a wetland restoration project in Germany’s Vogelsberg region that is expected to replenish more than 750 million litres of groundwater annually once completed. Led by environmental organisation NABU, the project will restore natural wetland conditions across 40 hectares in an important drinking-water catchment serving Frankfurt and surrounding communities. Amazon is contributing more than €2.9 million, while Microsoft is also providing funding.

 

Wetland Restoration Is Being Used to Recharge Groundwater

 

The project will restore land around the Alte Hasel and Eisenbachaue areas near Herbstein by removing artificial drainage systems, creating shallow water zones and depressions that slow runoff, and introducing extensive grassland management to reduce nutrient flows into streams.

NABU plans to work with around 10 local landholders and gradually acquire 80 hectares through 2028, with 40 hectares targeted for wetland restoration. The aim is to keep more rainfall in the landscape for longer, allowing water to infiltrate the ground and strengthen groundwater reserves used by Frankfurt and surrounding communities.

Amazon’s Frankfurt Water Projects Now Target 920 Million Litres Annually

 

The Vogelsberg project is Amazon’s third water replenishment initiative in Germany. It follows an urban leak-detection programme in Frankfurt with Shayp and a wetland restoration project in the Spessart Forest with EcoTree.

Together, Amazon says its contributions to the three projects are expected to return more than 920 million litres of water annually to communities and ecosystems in the greater Frankfurt region once completed. The work supports Amazon’s goal of returning more water to communities than it uses directly in its data-centre operations by 2030.

 

Tech Companies Are Treating Water as a Shared Regional Risk

 

The involvement of both Amazon and Microsoft reflects a broader approach to water stewardship around digital infrastructure. Rather than focusing only on reducing consumption inside individual facilities, the Vogelsberg project directs investment into the wider watershed that supports local communities and ecosystems.

“No single organisation can solve a region's water challenges alone. That's why projects like this matter — they bring together local expertise, environmental science, and resources from across the private sector to deliver measurable results for communities,” said Christian Schätz, COO of Microsoft Germany.

Biodiversity Benefits Extend Beyond Water Replenishment

 

Restoring the wetlands is also expected to create habitat for species including whinchats, snipe, wood sandpipers and gadwall. NABU plans annual monitoring of mammals, birds, insects, amphibians and reptiles between 2028 and 2038, providing more than a decade of data on the ecological effects of the restoration.

“For more than 20 years, NABU has worked with communities in the Vogelsberg to restore natural water systems. The project will return hundreds of millions of litres of water to the ground each year — while creating habitats for species like the whinchat that are disappearing from Germany's lowlands,” said Ingo Ammermann, CEO of NABU.

 

The 750 Million-Litre Target Will Be the Key Measure

 

Amazon has announced more than 70 water replenishment projects globally that it expects to return more than 40 billion litres of water annually. The Vogelsberg project stands out because it links corporate water stewardship directly with drinking-water resilience and ecosystem restoration in the Frankfurt region.

The key test will be whether the restored wetlands deliver the projected groundwater recharge as the project progresses through 2028 and beyond. Long-term ecological monitoring should also show whether the same intervention can strengthen water supply and biodiversity at the same time.
