Miejska Oczyszczalnia Sciekow w Skwierzynie - Municipal Wastewater Treatment Plant in Skwierzyna, Poland

Miejska Oczyszczalnia Sciekow w Skwierzynie is a municipal wastewater treatment plant located in Skwierzyna, in the Lubusz Voivodeship of western Poland. The facility serves a population of approximately 7,115 residents, classifying it as a small agglomeration under EU classification standards. As a Polish plant, it operates under national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires at least secondary treatment (biological treatment) to reduce organic pollutants and suspended solids. The plant's discharge must comply with Polish water law and environmental permits issued by regional authorities. The treated effluent is discharged into the local watershed, which ultimately drains into the Warta River, a major tributary of the Oder River. The Oder flows into the Baltic Sea via the Szczecin Lagoon. This downstream connection makes the plant's performance important for the ecological health of the Warta and Oder river systems, which support diverse aquatic life and are used for recreation and fisheries.

The plant's discharge enters the local water network that feeds into the Warta River, a key tributary of the Oder River. The Oder flows northward to the Baltic Sea via the Szczecin Lagoon, a sensitive estuarine ecosystem. The watershed supports diverse aquatic habitats and migratory fish species. Effective treatment helps protect water quality in this transboundary river system, which is ecologically important for the region.
