Szentlorinc Szennyviztisztito Telep - Advanced Wastewater Treatment in Kacsóta, Hungary

Szentlorinc Szennyviztisztito Telep is an advanced wastewater treatment plant located in Kacsóta, a settlement in the Szentlőrinci district of Baranya county, Hungary. The plant serves a population of about 4,850, placing it in the small-to-medium agglomeration category under Hungarian and EU regulations. It is situated in the Dél-Dunántúl (Southern Transdanubia) region, an area characterized by rolling hills and a continental climate. 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 agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 12,666 cubic meters per day, with an actual discharge volume of approximately 572 cubic meters per day, indicating significant spare capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The Dél-Dunántúl region includes several ecologically sensitive areas, and the plant's advanced treatment helps minimize nutrient loading and protect downstream aquatic ecosystems. The facility operates under Hungary's national water management framework, which implements EU directives.

The plant discharges into the Danube River basin, which flows through Hungary and several other countries before reaching the Black Sea. The Dél-Dunántúl region supports diverse aquatic life and is part of a larger watershed that includes important migratory corridors for fish. Advanced treatment at this plant reduces nutrient pollution, helping to prevent eutrophication in downstream lakes and coastal waters.
