Overview
KA Oldenburg is a large municipal wastewater treatment plant serving over 222,000 people in Oldenburg, Niedersachsen, Germany. It operates under the EU Urban Waste Water Treatment Directive.
KA Oldenburg (4030002001) is a major wastewater treatment facility located in the Drielake district of Oldenburg, Niedersachsen, Germany. Serving a population of over 222,000, it is classified as a large agglomeration under EU regulations. The plant is situated in the low-lying region of northwestern Germany, near the Hunte River. As a large agglomeration, the plant is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment for all agglomerations and tertiary treatment for those discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating substantial infrastructure. The treated effluent from KA Oldenburg is discharged into the Hunte River, which flows into the Weser River and ultimately into the North Sea. This watershed supports diverse aquatic life and is an important ecological corridor. The plant plays a critical role in protecting the water quality of the Hunte and downstream ecosystems.
Environmental context
KA Oldenburg discharges into the Hunte River, a tributary of the Weser River, which flows into the North Sea. The Hunte-Weser system supports a variety of fish species and migratory birds. The region's flat terrain and agricultural land use make the river susceptible to nutrient pollution, so effective treatment is essential to prevent eutrophication in the North Sea.
