Miedzywodzie Wastewater Treatment Plant, Zastań, Poland

Miedzywodzie wastewater treatment plant is located in Zastań, within gmina Wolin, powiat kamieński, in the województwo zachodniopomorskie region of Poland. The plant serves a population of approximately 10,485 people, placing it in the medium agglomeration category under Polish and EU regulations. As a Polish facility, Miedzywodzie operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Polish wastewater treatment plants are typically regulated by the Regional Water Management Board (RZGW) and must comply with national water law. The plant is located within 50 km of the Baltic Sea coast, and its treated effluent likely discharges into local watercourses that eventually drain into the Baltic Sea. The region's coastal and marine environment is ecologically sensitive, supporting diverse aquatic life and important migratory bird populations. Proper treatment is essential to protect these ecosystems from nutrient pollution and other contaminants.

The Miedzywodzie plant is situated in the coastal zone of the Baltic Sea, within the catchment area of the Odra River basin. Treated wastewater from the plant likely flows into local streams or directly into the Baltic Sea via the Świna or Dziwna straits. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it vulnerable to eutrophication from nutrient inputs. The surrounding area includes the Wolin National Park, an ecologically important region with diverse habitats for birds and aquatic species.
