KA Zeetze Wastewater Treatment Plant, Glienitz, Niedersachsen

KA Zeetze is an advanced wastewater treatment plant located in Glienitz, a village in the Samtgemeinde Elbtalaue, Lüchow-Dannenberg district, Niedersachsen, Germany. The plant serves a population of 4,080 and has a designed capacity of 7,600 m³/day, with a discharge volume of 387.45 m³/day. As an advanced treatment facility, KA Zeetze goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive water bodies under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires tertiary treatment for agglomerations over 10,000 PE in sensitive areas, but smaller plants like this may also adopt advanced treatment to meet local water quality standards. The plant's treated effluent is discharged into the Elbe River basin, which flows northward through Germany to the North Sea. The Elbe is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The advanced treatment helps protect the river's ecological health and downstream coastal waters.

KA Zeetze discharges into the Elbe River basin, which drains into the North Sea. The Elbe is a critical habitat for migratory fish species such as Atlantic salmon and sea trout, and its estuary supports important bird populations. The advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the river and the downstream Wadden Sea, a sensitive coastal ecosystem.
