Overview
Oczyszczalnia Sciekow w Kotorzu Malym serves approximately 13,500 residents in Kotórz Mały, Opole Voivodeship, Poland. The plant operates under EU Urban Waste Water Treatment Directive standards for medium-sized agglomerations.
Oczyszczalnia Sciekow w Kotorzu Malym is a municipal wastewater treatment plant located in Kotórz Mały, a village in the Opole region of southwestern Poland. The facility serves a population of approximately 13,474, classifying it as a medium-sized agglomeration under EU classification. Its location in the rural-urban fringe of the Turawa commune places it within the Oder River basin. As a Polish treatment plant serving over 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for agglomerations of this size. Polish national regulations transpose these requirements, and the plant is expected to meet effluent standards for biochemical oxygen demand, chemical oxygen demand, and suspended solids. The facility's design capacity and treatment process details are not publicly available, but compliance with the directive ensures appropriate treatment for the population served. The plant discharges treated wastewater into local watercourses that eventually flow into the Oder River, a major Central European waterway. The Oder drains into the Baltic Sea via the Szczecin Lagoon, making the plant's operations relevant to downstream water quality in both Polish and German territories. The surrounding area includes agricultural land and small water bodies, emphasizing the need for effective nutrient removal to protect aquatic ecosystems.
Environmental context
The plant's treated effluent enters local streams within the Oder River basin, which flows northward to the Baltic Sea via the Szczecin Lagoon. This watershed supports diverse aquatic life and is an important ecological corridor in Central Europe. Effective treatment is crucial to prevent nutrient enrichment and maintain water quality in downstream rivers and the sensitive coastal lagoon ecosystem.
