Szakald Szennyviztisztito Telep - Advanced Wastewater Treatment in Szakáld, Hungary

Szakald Szennyviztisztito Telep is an advanced wastewater treatment plant located in Szakáld, a village in the Borsod-Abaúj-Zemplén county of northern Hungary. The plant serves a small population of 217 residents, reflecting its role in a rural community. Its designed capacity of 300 m³/day indicates it is sized to accommodate local wastewater flows, with current discharge volume at 25.58 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for smaller agglomerations. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) and disinfection, ensuring high-quality effluent. As a Hungarian facility, it operates under national regulations that transpose EU directives, with oversight from the relevant water authority. The treated effluent is discharged into local watercourses that ultimately drain into the Tisza River basin, a major tributary of the Danube. The Tisza River flows southward through Hungary and into Serbia, eventually reaching the Black Sea. The advanced treatment helps protect the ecological health of these downstream waters, which support diverse aquatic life and are important for regional biodiversity.

The plant's discharge enters the Tisza River basin, which flows into the Danube River and ultimately the Black Sea. The Tisza is a significant river in Central Europe, supporting diverse fish species and migratory birds. The advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream lakes and coastal areas. The region's watershed is ecologically sensitive, with floodplain forests and wetlands that rely on good water quality.
