Kaposvar Szennyviztisztito Telep - Wastewater Treatment Plant in Sántos, Hungary

Kaposvar Szennyviztisztito Telep is a wastewater treatment plant located in Sántos, within the Dél-Dunántúl region of Hungary. It serves a population of approximately 127,046, classifying it as a large agglomeration under EU regulations. The plant is situated near the city of Kaposvár and plays a key role in managing municipal wastewater for the surrounding area. As a large agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum, and tertiary treatment if the receiving waters are sensitive. Typical facilities of this scale in Hungary employ activated sludge systems with nutrient removal to meet discharge standards. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, which flows into the Black Sea. The plant's operations help protect downstream aquatic ecosystems, including the Danube Delta, a region of high ecological importance that supports diverse fish and bird species.

The plant's discharge enters the Kapos River, a tributary of the Sió River, which flows into the Danube River. The Danube ultimately reaches the Black Sea, supporting a vast watershed that includes ecologically sensitive areas such as floodplain forests and wetlands. The plant's nutrient removal is critical to prevent eutrophication in downstream water bodies.
