Overview
KA Osnabrück_Eversburg is a large municipal wastewater treatment plant serving 218,783 people in Osnabrück, Niedersachsen, Germany. It discharges into the Hase River, a tributary of the Ems, ultimately reaching the North Sea.
KA Osnabrück_Eversburg (plant ID 4040002001) is a major wastewater treatment facility located in the Hafen district of Osnabrück, Niedersachsen, Germany. Serving a population of approximately 218,783, it is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD) 91/271/EEC, which requires advanced treatment for sensitive areas. As a large-scale plant, it is expected to provide at least secondary treatment, with tertiary treatment likely given the population size and the sensitivity of the receiving waters. The plant operates under Germany's national water management framework, which implements the EU UWWTD through the Water Resources Act (WHG) and state-level regulations. Discharge permits are issued by the Lower Saxony Water Management, Coastal Defence and Nature Conservation Agency (NLWKN). The treated effluent is discharged into the Hase River, which flows through Osnabrück and joins the Ems River near Meppen. The Ems then drains into the Dollart estuary and the North Sea. The Hase-Ems system supports diverse aquatic life and is an important ecological corridor in the region. The plant's location inland, about 50 km from the coast, reduces direct marine impact, but nutrient loads can affect the Ems estuary.
Environmental context
The plant discharges into the Hase River, a tributary of the Ems River, which flows into the Dollart estuary and the North Sea. The Hase-Ems system is ecologically sensitive, supporting fish migration and diverse aquatic habitats. Nutrient and pollutant loads from the plant can influence water quality in the estuary, which is important for bird populations and coastal ecosystems.
Frequently asked questions
The plant is located at Haseuferweg in the Hafen district of Osnabrück, Niedersachsen, Germany.
The plant serves approximately 218,783 people, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive.
Treated effluent is discharged into the Hase River, which flows into the Ems River and eventually reaches the North Sea.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), implemented in Germany via the Water Resources Act (WHG). Discharge permits are issued by the Lower Saxony state authority (NLWKN).
For large agglomerations over 150,000 population equivalent, the EU UWWTD requires secondary treatment, and tertiary treatment is often mandated in sensitive areas. German plants of this scale typically employ advanced biological treatment with nutrient removal.
