Seehausen Wastewater Treatment Plant, Seehausen (Altmark), Saxony-Anhalt, Germany

The Seehausen wastewater treatment plant is located in the town of Seehausen (Altmark), within the Stendal district of Saxony-Anhalt, Germany. It serves a population of approximately 4,688 residents, providing advanced treatment to meet stringent environmental standards. The plant has a designed capacity of 6,000 m³/day and currently treats an average daily flow of 387.97 m³/day. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced (tertiary) treatment for discharges into sensitive areas. The plant's advanced treatment level ensures high removal of nutrients and organic pollutants, aligning with the directive's requirements for agglomerations of this size. The treated effluent is discharged into local watercourses that drain into the Elbe River basin. The Elbe flows northward through Germany and into the North Sea, supporting diverse aquatic ecosystems. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Elbe River basin, which flows through Saxony-Anhalt and eventually reaches the North Sea. The Elbe is a major European river supporting diverse fish species and migratory birds. The advanced treatment at Seehausen reduces nutrient loading, helping to prevent eutrophication in downstream waters and the North Sea coastal zone.
