Sinzing Wastewater Treatment Plant, Regensburg, Bavaria, Germany

The Sinzing wastewater treatment plant is located in the Regensburg district of Bavaria, Germany. It serves a population of 2,038 and operates with advanced treatment technology, ensuring high-quality effluent before discharge. With a designed capacity of 5,800 m³/day and an actual discharge volume of 826.95 m³/day, the plant operates well below its capacity. As a German facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all agglomerations. The plant's advanced treatment level meets the highest standards for nutrient removal. The treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin. The Danube flows through multiple countries before reaching the Black Sea, supporting diverse aquatic ecosystems along its course. The plant plays a key role in protecting downstream water quality in this ecologically significant river system.

The plant discharges into the Danube River basin, a major European waterway that flows through ten countries to the Black Sea. The Danube supports a rich diversity of fish, birds, and aquatic plants, including several endemic species. The advanced treatment at Sinzing helps reduce nutrient loads, preventing eutrophication in downstream lakes and the Black Sea coastal zone.
