ECOLO CHIEFF Wastewater Treatment Plant, Czerna, Poland

ECOLO CHIEFF is a wastewater treatment plant located in Czerna, within the gmina Iłowa, powiat żagański, województwo lubuskie, Poland. The plant serves a population of approximately 2.6 million, classifying it as a large agglomeration under EU regulations. It is situated inland, more than 50 km from the coast. As a large-scale facility in Poland, ECLO CHIEFF operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The regulatory framework ensures compliance with stringent standards for such large agglomerations. The plant discharges treated wastewater into local water bodies, likely within the Oder River basin, which flows into the Baltic Sea. The facility plays a crucial role in protecting the region's water quality and downstream ecosystems, supporting aquatic life and reducing nutrient pollution in the Baltic Sea.

The plant is located in the Oder River basin, which drains into the Baltic Sea. The Oder River and its tributaries support diverse aquatic ecosystems, including fish spawning grounds and migratory corridors. The Baltic Sea is a sensitive marine environment prone to eutrophication, making effective nutrient removal critical. The plant's operations help mitigate pollution impacts on these water bodies.
