Trittau Wastewater Treatment Plant, Schleswig-Holstein, Germany

The Trittau wastewater treatment plant is located in the town of Trittau, in the district of Stormarn, Schleswig-Holstein, Germany. The facility serves a population of approximately 18,079 people, placing it in the medium agglomeration category under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 10,000 and 100,000 are required to provide secondary treatment as a minimum. The regulatory framework ensures that the plant meets these standards to protect the local environment. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Elbe River basin and the North Sea. The plant plays a key role in maintaining water quality in the region, supporting aquatic ecosystems and downstream uses.

The Trittau plant discharges into the local watershed, which is part of the Elbe River basin. The Elbe flows through northern Germany and empties into the North Sea, a sensitive marine environment. The treatment plant helps protect downstream aquatic habitats, including fish spawning grounds and migratory corridors, by reducing nutrient and pollutant loads.
