Csolnok Szennyviztisztito Telep - Advanced Wastewater Treatment in Csolnok, Hungary

Csolnok Szennyviztisztito Telep is an advanced wastewater treatment facility located in Csolnok, within the Közép-Dunántúl region of Hungary. The plant serves a population of around 1,577, reflecting its role in managing domestic wastewater for this small community. Its designed capacity of 2,750 m³/day indicates sufficient headroom for current and future needs. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations under 10,000 population equivalent, the directive requires appropriate treatment, and Hungary mandates advanced treatment in sensitive areas to protect water quality. The plant discharges treated effluent into local watercourses that ultimately drain into the Danube River basin. The Danube flows through Hungary and into the Black Sea, making the plant's advanced treatment crucial for reducing nutrient loads and protecting downstream ecosystems, including the Danube Delta, a region of high ecological importance.

The plant's treated effluent enters local streams that feed into the Danube River, which flows through Hungary and into the Black Sea. The Danube basin supports diverse aquatic life and is a critical migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream water quality and the ecological health of the Danube Delta.
