Jánosháza Szennyvíztisztító Telep - Advanced Wastewater Treatment in Jánosháza, Hungary

Jánosháza Szennyvíztisztító Telep is a municipal wastewater treatment facility located in Jánosháza, a town in Vas County within the Nyugat-Dunántúl region of Hungary. The plant serves a population of approximately 3,051 residents and has a designed capacity of 4,535 cubic meters per day, with an average discharge volume of 359.66 m³/day. As an advanced treatment plant, it employs processes that go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This level of treatment is consistent with Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations based on population equivalents and the sensitivity of receiving waters. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region's rivers and groundwater.

The plant discharges into local streams that are part of the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The region's water bodies support diverse aquatic life and are important for agriculture and local communities. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream lakes and coastal areas.
