3524092021 KA Ihlienworth - Closed Advanced Wastewater Treatment Plant in Ihlienworth, Germany

3524092021 KA Ihlienworth is a former wastewater treatment plant located in Ihlienworth, a municipality in the Samtgemeinde Land Hadeln, Landkreis Cuxhaven, Niedersachsen, Germany. The plant served a small population of 641 residents and was designed with a capacity of 2000 cubic meters per day. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Although the plant is now closed, its advanced treatment level reflects the sensitivity of the local environment, likely due to its proximity to the coast. The plant is situated within 10 km of the North Sea coast, indicating its discharge likely affected coastal waters. The region drains into the North Sea via the Elbe and Weser estuaries, supporting diverse aquatic life and important migratory bird habitats along the Wadden Sea coast.

The plant is located in the low-lying marshlands of Niedersachsen, near the North Sea coast. Its treated effluent would have entered the drainage network leading to the Elbe or Weser estuaries, which flow into the North Sea. This coastal zone is ecologically sensitive, supporting diverse aquatic life and serving as a critical stopover for migratory birds along the East Atlantic Flyway.
