Impfstoffw Tornau Wastewater Treatment Plant, Roßlau, Saxony-Anhalt

Impfstoffw Tornau is an advanced wastewater treatment plant located in the Roßlau district of Dessau-Roßlau, in the state of Saxony-Anhalt, Germany. The plant serves a population of 1,556 and has a designed capacity of 6,900 m³/day, with an average discharge volume of 642.63 m³/day. As an advanced treatment facility, Impfstoffw Tornau goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive water bodies under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires tertiary treatment for agglomerations of this size if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Elbe River. The Elbe basin is a major European watershed, supporting diverse aquatic life and providing drinking water for millions. Advanced treatment at this plant helps protect downstream ecosystems and water quality in the Elbe and its tributaries.

The plant discharges into the Elbe River basin, which flows through Germany and into the North Sea. The Elbe is a major European river supporting diverse aquatic habitats and migratory fish species. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the river and its estuary, which is ecologically sensitive.
