Regis Wastewater Treatment Plant, Regis-Breitingen, Saxony, Germany

The Regis wastewater treatment plant is located in Regis-Breitingen, a town in the Landkreis Leipzig district of Saxony, Germany. It serves a population of approximately 3,600 residents, placing it in the small 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 3,500 m³/day and an actual discharge volume of 447.9 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Treated effluent is discharged into local watercourses 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 in this ecologically sensitive region.

The plant discharges into local streams that are part of the Elbe River basin. The Elbe flows north through Germany to the North Sea, supporting important fish populations and migratory bird habitats. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters.
