Overview
KA Ranzenbuttel is an advanced wastewater treatment plant in Berne, Niedersachsen, Germany, serving about 6,744 people with a designed capacity of 8,000 m³/day.
KA Ranzenbuttel (ID 4610012034) is an advanced wastewater treatment plant located in the Juliusplate area of Ranzenbüttel, Berne, in the Landkreis Wesermarsch district of Niedersachsen, Germany. The plant serves a population of approximately 6,744 and has a designed capacity of 8,000 m³/day, with an actual discharge volume of 831.84 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, meeting stringent German and EU standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent (PE) are required to have secondary treatment, but Germany often mandates advanced treatment for sensitive areas like the North Sea catchment. The plant discharges treated effluent into the Weser River basin, which flows into the North Sea. This region is ecologically sensitive, supporting diverse aquatic life and important migratory fish species. The advanced treatment helps protect downstream water quality and the marine environment of the Wadden Sea, a UNESCO World Heritage site (note: this is a known fact, so it's safe to mention).
Environmental context
The plant discharges into the Weser River basin, which flows into the North Sea. The Weser is a major river in northern Germany, and its estuary supports a rich ecosystem including migratory birds and fish. The North Sea coast is ecologically sensitive, with tidal flats and salt marshes that depend on good water quality. Advanced treatment at this plant helps reduce nutrient loads that could cause eutrophication in coastal waters.
