Overview
Dranske wastewater treatment plant serves the Lancken area on the island of Rügen, Germany. It provides advanced treatment for a population of 2,072 and discharges treated water near the Baltic Sea coast.
The Dranske wastewater treatment plant is located in Lancken, within the municipality of Dranske on the island of Rügen in Mecklenburg-Vorpommern, Germany. It serves a population of approximately 2,072 and is situated less than 10 km from the Baltic Sea coast, making it a coastal facility. As an advanced treatment plant, Dranske goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is critical for protecting sensitive coastal waters. The plant has a designed capacity of 7,000 m³/day and currently discharges about 408 m³/day of treated effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants in sensitive coastal areas are required to achieve tertiary treatment, which this facility meets. The treated effluent from Dranske ultimately reaches the Baltic Sea, a brackish inland sea with limited water exchange. The Baltic Sea is highly sensitive to nutrient pollution, which can cause eutrophication and algal blooms. Advanced treatment at this plant helps reduce nutrient loads, supporting the ecological health of the coastal waters around Rügen.
Environmental context
The Dranske plant discharges into the Baltic Sea, a semi-enclosed sea connected to the North Sea via the Kattegat and Skagerrak. The Baltic Sea is particularly vulnerable to eutrophication due to its narrow connection to the ocean and long residence time. Nutrient inputs from wastewater contribute to algal blooms and oxygen depletion in bottom waters. Advanced treatment at this plant reduces nitrogen and phosphorus loads, helping to protect the sensitive coastal ecosystem of the Rügen region, which supports diverse marine life and is an important area for migratory birds.
Frequently asked questions

The Dranske plant serves a population of approximately 2,072 people in the Lancken and Dranske area.
The Dranske plant discharges treated wastewater into the Baltic Sea, as it is located less than 10 km from the coast. The advanced treatment process removes nutrients to protect the sensitive marine environment.
The Dranske plant provides advanced treatment, which includes nutrient removal (nitrogen and phosphorus) beyond secondary treatment. This is required under the EU Urban Waste Water Treatment Directive for discharges into sensitive coastal areas.
As a German wastewater treatment plant, Dranske operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for agglomerations discharging into sensitive areas like the Baltic Sea. Compliance is enforced by German state authorities.
