ZKA Bernsdorf Wastewater Treatment Plant, Bernsdorf, Saxony

ZKA Bernsdorf is an advanced wastewater treatment plant located in Bernsdorf, a town in the district of Bautzen, Saxony, Germany. The facility serves a population of approximately 4,294 residents and is part of the municipal wastewater infrastructure for the region. The plant operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,500 m³/day and an actual discharge volume of 644.10 m³/day, the plant has ample capacity to handle current loads. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, and the advanced level here exceeds that standard. The treated effluent is discharged into local water bodies that ultimately drain into the Elbe River basin. The Elbe flows through Saxony and into the North Sea, supporting diverse aquatic ecosystems. The plant's advanced treatment helps protect downstream water quality and ecological health in the region.

The plant discharges into the local watershed, which is part of the Elbe River basin. The Elbe flows northward through Germany to the North Sea, supporting diverse aquatic life and serving as an important migratory corridor for fish. The advanced treatment at ZKA Bernsdorf reduces nutrient loads, helping to prevent eutrophication in downstream waters and contributing to the ecological health of the Elbe estuary.
