Wegorzewo Wastewater Treatment Plant - Węgorzewo, warmińsko-mazurskie, Poland

The Wegorzewo wastewater treatment plant is located in the town of Węgorzewo, in the warmińsko-mazurskie province of northeastern Poland. The facility serves a population of about 13,420 people, placing it in the medium agglomeration category under Polish and EU regulations. As a Polish plant serving a medium-sized community, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with national and European standards for wastewater treatment. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Baltic Sea via the Pregola River system. This region is part of the Vistula Lagoon catchment area, an ecologically sensitive coastal zone that supports diverse aquatic life and migratory bird populations. Proper treatment is essential to protect the lagoon's water quality and the broader Baltic Sea ecosystem.

The Wegorzewo plant discharges into the local watershed that feeds into the Pregola River, which flows into the Vistula Lagoon and then the Baltic Sea. The Vistula Lagoon is a shallow coastal lagoon that supports diverse aquatic life and serves as an important migratory corridor for birds. The region's ecology depends on effective wastewater treatment to prevent nutrient loading and eutrophication in this sensitive water body.
