Csikostottos Szennyviztisztito Telep - Advanced Wastewater Treatment in Csikóstőttős, Hungary

Csikostottos Szennyviztisztito Telep is an advanced wastewater treatment facility located in Csikóstőttős, a village in Tolna County within the Dél-Dunántúl region of Hungary. The plant serves a population of approximately 550 residents, reflecting its role in managing domestic wastewater for this small rural community. 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. With a designed capacity of 890 m³/day and an actual discharge volume of 64.84 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin via the Kapos River. The Danube flows into the Black Sea, making this plant part of a broader transboundary water management system. Advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the sensitive Danube delta region.

The plant discharges into the Kapos River, a tributary of the Danube, which flows into the Black Sea. The Danube basin supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and contributing to the ecological health of the Black Sea coastal zone.
