KA Marienhafe Wastewater Treatment Plant, Marienhafe, Niedersachsen

KA Marienhafe is a municipal wastewater treatment plant located in Marienhafe, a town in the Samtgemeinde Brookmerland, Landkreis Aurich, Niedersachsen, Germany. The plant serves a population of approximately 10,915, placing it in the medium agglomeration category under German and EU regulations. As a German wastewater treatment plant, KA Marienhafe operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating a facility sized to handle the local wastewater load. The plant's treated effluent ultimately discharges into the North Sea via local waterways. The region is part of the Ems-Weser-Elbe watershed, with the plant's discharge contributing to the coastal and marine environment of the Wadden Sea, an ecologically sensitive area that supports diverse aquatic life and migratory bird populations.

KA Marienhafe discharges into the local drainage network that flows toward the North Sea, specifically into the Wadden Sea ecosystem. This coastal region is characterized by tidal flats and salt marshes that provide critical habitat for fish, birds, and marine invertebrates. The plant's location within 50 km of the coast means its effluent can influence nearshore water quality, making nutrient removal and treatment standards important for protecting the sensitive marine environment.
