Prettin Wastewater Treatment Plant, Sachsen-Anhalt, Germany

The Prettin wastewater treatment plant is located in the town of Prettin, part of Annaburg in Wittenberg district, Sachsen-Anhalt, Germany. The facility serves a population of approximately 2,284 and operates with secondary treatment, meeting the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for small agglomerations. With a designed capacity of 2,200 m³/day and an average discharge volume of 191 m³/day, the plant operates well below its capacity. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local water bodies that eventually drain into the Elbe River basin. The Elbe flows through Germany and into the North Sea, supporting diverse aquatic ecosystems and providing important habitat for migratory fish species.

The plant discharges into the Elbe River basin, which flows northward through Germany and into the North Sea. The Elbe supports a variety of aquatic life and is an important migratory corridor for fish such as Atlantic salmon and European eel. The region's watershed includes agricultural and forested areas, contributing to nutrient loads that the plant helps mitigate through secondary treatment.
