Lenzen Wastewater Treatment Plant: Advanced Treatment in Brandenburg, Germany

The Lenzen wastewater treatment plant is located in Lenzen (Elbe), a town in the Prignitz district of Brandenburg, Germany. It serves a population of approximately 3,500 residents, making it a small-scale municipal facility. The plant is situated near the Elbe River, which is a major waterway in Central Europe. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 5,632 m³/day, and it currently discharges about 281 m³/day of treated wastewater. The facility operates under Germany's national water management regulations, which implement EU directives and ensure high environmental standards. Treated effluent from the Lenzen plant flows into the Elbe River, which drains into the North Sea near Cuxhaven. The Elbe basin supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment helps protect water quality in the river and downstream ecosystems.

The Lenzen plant discharges into the Elbe River, which flows through Germany to the North Sea. The Elbe basin is ecologically significant, supporting diverse aquatic habitats and serving as a key migratory route for fish such as salmon and eel. Advanced treatment at the plant helps minimize nutrient and pollutant loads, protecting downstream water quality in the river and the North Sea.
