Ruda Kozielska Wastewater Treatment Plant - Closed Secondary Facility in Silesia

The Ruda Kozielska wastewater treatment plant is located in the village of Ruda Kozielska, within the gmina Kuźnia Raciborska in województwo śląskie, Poland. It served the local community as a secondary treatment facility before its closure. As a Polish plant, it operated under national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant's designed capacity of 7000 m³/day indicates it was sized for a moderate population load. The plant's discharge would have entered local waterways within the Oder River basin, ultimately draining into the Baltic Sea. Its closure means wastewater from the area is now likely handled by other regional facilities, maintaining protection for local water quality and downstream ecosystems.

The plant is situated inland in southern Poland, within the Oder River basin. Its treated effluent would have flowed into local tributaries of the Oder, which drains into the Szczecin Lagoon and then the Baltic Sea. The region supports diverse aquatic life and is part of an important migratory corridor for fish species.
