KA Rodenkirchen Hartwarden Wastewater Treatment Plant, Stadland, Niedersachsen

The KA Rodenkirchen Hartwarden wastewater treatment plant is located in Stadland, within the Landkreis Wesermarsch district of Niedersachsen, Germany. The plant serves a population of approximately 4,617 residents and has a designed capacity of 1.00, indicating it is a small-scale facility tailored to the local community's needs. As a German wastewater treatment plant, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment. For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment to meet quality standards, typically secondary treatment or equivalent, depending on the sensitivity of the receiving waters. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Weser River and then into the North Sea. The region is characterized by low-lying marshlands and is part of the Weser estuary ecosystem, which supports diverse aquatic life and is an important area for migratory birds. The plant plays a key role in protecting this sensitive environment from nutrient pollution.

The plant discharges into the local drainage network that flows into the Weser River, a major waterway in northern Germany. The Weser River empties into the North Sea, creating an estuary that is ecologically sensitive and supports diverse aquatic life, including fish and bird species. The region's low-lying marshlands and proximity to the coast make it important to manage nutrient loads to prevent eutrophication in the North Sea.
