KA Aurich Wastewater Treatment Plant, Aurich, Niedersachsen

KA Aurich is a municipal wastewater treatment plant located in Aurich, Niedersachsen, Germany. The facility serves a population of approximately 66,267 people, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated in the Leegland area, within the Aurich district, and plays a key role in managing the region's wastewater. As a German plant serving over 10,000 population equivalent, KA Aurich is required to meet the standards of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment as a minimum, with tertiary treatment required if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1. 00 (likely in thousands of cubic meters per day or similar unit), indicating a significant infrastructure investment. The treated effluent from KA Aurich is discharged into local water bodies that ultimately drain into the North Sea via the Ems River system. The region's flat, low-lying terrain and proximity to the Wadden Sea, a UNESCO World Heritage site (though not named here), make nutrient removal particularly important to prevent eutrophication in coastal waters. The plant's operations help protect the ecological health of the downstream aquatic environment.

KA Aurich discharges into the local drainage network that flows into the Ems River, which then empties into the North Sea. The receiving waters are part of the Wadden Sea ecosystem, an ecologically sensitive intertidal zone that supports diverse bird populations and marine life. Nutrient loading from wastewater must be carefully managed to prevent algal blooms and maintain water quality in this dynamic coastal environment.
