Bacsalmas Szennyviztisztito Telep - Advanced Wastewater Treatment in Bácsalmás, Hungary

Bacsalmas Szennyviztisztito Telep is an advanced wastewater treatment plant located in Bácsalmás, a town in the Dél-Alföld region of Hungary. The plant serves a population of 2,121 and has a designed capacity of 3,000 m³/day, with a current discharge volume of 250.03 m³/day. As an advanced treatment facility, it provides a higher level of pollutant removal than conventional secondary treatment. The plant operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. For populations under 10,000, the directive mandates secondary treatment, but Hungary has opted for advanced treatment at this facility, likely due to local environmental sensitivity or regulatory requirements. The treated effluent is discharged into local watercourses that drain into the Danube River basin, ultimately reaching the Black Sea. The Dél-Alföld region is characterized by flat terrain and agricultural land, where water quality protection is important for both ecological health and human use. The advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream waters.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Dél-Alföld region is part of the Great Hungarian Plain, an area with significant agricultural activity and sensitive aquatic ecosystems. Advanced treatment at this facility helps protect downstream water quality by reducing organic matter and nutrient pollution, supporting biodiversity in rivers and wetlands along the Danube corridor.
