Marburg _ Schrock Wastewater Treatment Plant, Marburg, Hessen, Germany

Marburg _ Schrock is an advanced wastewater treatment plant located in the Schröck district of Marburg, Hessen, Germany. The plant serves a population of 4,900 and is part of the municipal wastewater infrastructure for the city of Marburg, situated in the Lahn river valley. As an advanced treatment facility, Marburg _ Schrock goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 4,900 cubic meters per day and currently discharges 996.45 cubic meters daily, indicating significant spare capacity. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Lahn River, a tributary of the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic life and providing drinking water for millions. The advanced treatment helps protect downstream ecosystems and water quality in the Rhine delta.

The plant discharges into the Lahn River, which flows into the Rhine River and eventually reaches the North Sea. The Lahn is a medium-sized river in central Germany that supports fish species such as brown trout and grayling. The advanced treatment at Marburg _ Schrock reduces nutrient loading, helping to prevent eutrophication in the Rhine and North Sea coastal waters.
