Horpacs Szennyviztisztito Telep - Advanced Wastewater Treatment in Horpács, Hungary

Horpacs Szennyviztisztito Telep is an advanced wastewater treatment facility located in Horpács, a village in Nógrád county within the Észak-Magyarország region of Hungary. The plant serves a population of approximately 1,589 people, reflecting its role in managing domestic wastewater for this rural community. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires appropriate treatment for agglomerations of this size, and advanced treatment is often mandated in sensitive areas to protect water quality. The treated effluent is discharged into local watercourses that drain into the Ipoly River, a tributary of the Danube. The Danube ultimately flows into the Black Sea, making the plant's performance important for downstream ecosystems. The advanced treatment helps reduce nutrient loading and supports the ecological health of the receiving waters.

The plant discharges into local streams that feed the Ipoly River, which flows into the Danube River and eventually reaches the Black Sea. This watershed supports diverse aquatic life and is part of a larger transboundary basin. The advanced treatment level helps minimize nutrient pollution, which is critical for preventing eutrophication in downstream water bodies and maintaining ecological balance in the region.
