Mollenhagen Wastewater Treatment Plant, Wendorf, Mecklenburg-Vorpommern

The Mollenhagen wastewater treatment plant is located in Wendorf, near Möllenhagen, in the Mecklenburgische Seenplatte district of Mecklenburg-Vorpommern, Germany. It served a population of 1,312 people and is now closed. The plant provided advanced treatment, meeting high standards for effluent quality. As a German facility, the plant operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The designed capacity was 2,100 m³/day, with an actual discharge volume of 332.04 m³/day, indicating a utilization rate well below capacity. The plant's discharge likely entered local watercourses that drain into the Baltic Sea via the Warnow or Peene river systems. The region is characterized by numerous lakes and wetlands, making water quality protection important for aquatic ecosystems and recreational use.

The plant is situated inland in the Mecklenburg Lake District, an area with many interconnected lakes and rivers. Treated effluent would have flowed into local streams and eventually into the Baltic Sea, a sensitive marine environment. The region supports diverse aquatic life and is important for migratory birds. Advanced treatment helps minimize nutrient loading, protecting downstream waters from eutrophication.
