Kladen Wastewater Treatment Plant, Bismark (Altmark), Sachsen-Anhalt

Kladen wastewater treatment plant is located in the Kläden district of Bismark (Altmark), in the state of Sachsen-Anhalt, Germany. The facility serves a population of approximately 8,240 people, classifying it as a small to medium agglomeration under European Union regulations. As a German wastewater treatment plant, Kladen operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into inland waters, ensuring compliance with environmental standards. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Elbe River basin. The Elbe flows through northern Germany into the North Sea, supporting diverse aquatic ecosystems along its course. The plant plays a key role in protecting the local watershed and downstream environments from pollution.

The plant discharges into the Elbe River basin, which flows through Sachsen-Anhalt and northern Germany before reaching the North Sea. The Elbe supports a variety of fish species and migratory birds, making it an ecologically important waterway. Effective wastewater treatment at Kladen helps maintain water quality in this sensitive river system.
