Bank Szennyviztisztito Telep - Bánk Wastewater Treatment Plant, Hungary

Bank Szennyviztisztito Telep is a municipal wastewater treatment facility located in Bánk, a village in Nógrád County, northern Hungary. The plant serves a small population of 340 residents, reflecting its role in a rural community. It operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for treatment based on agglomeration size. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 890 cubic meters per day and an actual discharge volume of 40.08 cubic meters per day, the facility operates well below its capacity, indicating it can accommodate future growth. As a small agglomeration, the EU directive requires appropriate collection and treatment to protect the environment. The treated effluent is discharged into local surface waters, which eventually drain into the Danube River basin and the Black Sea. The plant plays a key role in preventing pollution in the region's streams and groundwater, supporting aquatic life and downstream water quality in the broader Carpathian Basin ecosystem.

The plant discharges into local streams that are part of the Danube River basin, ultimately flowing into the Black Sea. The surrounding region features a mix of agricultural land and forests, with sensitive aquatic habitats that rely on effective wastewater treatment to prevent nutrient enrichment and maintain biodiversity. The plant's secondary treatment helps reduce organic pollution, supporting the ecological health of downstream water bodies.
