KA Eckwarden Wastewater Treatment Plant, Butjadingen, Niedersachsen

KA Eckwarden, located in the Eckwarden district of Butjadingen, Niedersachsen, Germany, is a closed wastewater treatment facility that previously served a small population of 465. The plant was designed with an advanced treatment level and a capacity of 3,000 m³/day, though it is no longer operational. As a German plant, it operated under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for small agglomerations. The advanced treatment level indicates that the plant likely employed nutrient removal or other tertiary processes to meet stringent discharge standards. The plant is situated within 10 km of the North Sea coast, highlighting its role in protecting coastal water quality. Although the specific receiving water body is not named, the treated effluent would have discharged into local waterways draining into the North Sea, supporting the ecological health of the Wadden Sea region.

The plant is located near the North Sea coast in the Wesermarsch district, an area characterized by low-lying marshlands and a network of drainage canals. Treated effluent from the plant would have flowed into local watercourses that eventually reach the North Sea, a sensitive marine environment supporting diverse aquatic life and important bird populations. The advanced treatment level helped minimize nutrient and pollutant loads to these coastal waters.
