Parey Wastewater Treatment Plant, Elbe-Parey, Saxony-Anhalt, Germany

The Parey wastewater treatment plant is located in Elbe-Parey, a municipality in the Jerichower Land district of Saxony-Anhalt, Germany. It serves a population of approximately 8,947 people, placing it in the small-to-medium agglomeration category under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 9,500 m³/day and an average discharge volume of 678.96 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into the local water system, which ultimately drains into the Elbe River basin. The Elbe River is a major waterway in Central Europe, flowing through Germany and into the North Sea. The plant's advanced treatment helps protect the ecological health of the Elbe and its tributaries, supporting aquatic life and downstream water quality.

The Parey plant discharges into the Elbe River basin, which flows through Saxony-Anhalt and eventually reaches the North Sea. The Elbe is a vital ecological corridor supporting diverse fish species, migratory birds, and riparian habitats. Advanced treatment at this plant reduces nutrient loads and pollutants, helping to maintain the ecological balance of the river and its downstream estuary.
