Overview
Klarwerksverbund Kohlbrandhoft Dradenau is a major wastewater treatment plant serving Hamburg, Germany. It treats wastewater for approximately 2.3 million people, operating under the EU Urban Waste Water Treatment Directive.
Klarwerksverbund Kohlbrandhoft Dradenau is a key wastewater treatment facility located in the Waltershof district of Hamburg, Germany. Serving a population of around 2.3 million, it is one of the largest treatment plants in the region, handling municipal wastewater from the Hamburg metropolitan area. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide at least secondary treatment, with tertiary treatment expected for sensitive areas. The plant's designed capacity is 1.00 (likely in million cubic meters per day or similar unit), indicating substantial infrastructure to manage high-volume flows. The treated effluent is discharged into the Elbe River, which flows into the North Sea. This discharge point is critical for maintaining water quality in the Elbe estuary and downstream marine environment, supporting diverse aquatic life and commercial fisheries.
Environmental context
The plant discharges into the Elbe River, which flows through Hamburg and into the North Sea approximately 100 km downstream. The Elbe estuary is an ecologically sensitive area supporting migratory fish species and bird populations. Nutrient loading from wastewater can contribute to eutrophication in the North Sea, making advanced treatment important for protecting coastal waters.
