The Koprivnica wastewater treatment plant is located in Herešin, Grad Koprivnica, in the Koprivničko-križevačka županija region of Croatia. It serves the city of Koprivnica and surrounding areas, providing advanced treatment to protect local water resources. The plant's designed capacity is 100,000 cubic meters per day, indicating it is a large-scale facility. As an advanced treatment plant, Koprivnica goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Croatia, as an EU member state, requires tertiary treatment for agglomerations over 10,000 population equivalent in sensitive areas. This plant's advanced level aligns with such requirements, ensuring high-quality effluent. The treated wastewater is discharged into the local watershed, which ultimately drains into the Drava River, a major tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international basin. The advanced treatment helps protect downstream ecosystems, including the Drava's diverse aquatic life and the Danube Delta's sensitive habitats.
Environmental context
