Sur Szennyviztisztito Telep - Advanced Wastewater Treatment in Súr, Hungary

Sur Szennyviztisztito Telep is an advanced wastewater treatment plant located in the rural settlement of Súr, within the Közép-Dunántúl region of Hungary. The plant serves a small population of 1,527 residents, reflecting its role in managing domestic wastewater for this community. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 1,083 m³/day and currently discharges 180.01 m³/day of treated wastewater. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like Súr (population under 2,000) are required to provide appropriate treatment, and the advanced level here exceeds the minimum secondary treatment standard. The plant operates within Hungary's national water management framework, which aligns with EU directives. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, a major European waterway flowing into the Black Sea. The advanced treatment helps protect downstream aquatic ecosystems, including the Danube's diverse fish and invertebrate communities, by reducing nutrient loads and organic pollution.

The plant discharges into local streams that are part of the Danube River basin. The Danube flows through Hungary and several other countries before reaching the Black Sea, supporting a rich array of aquatic life including over 60 fish species. The advanced treatment at Sur Szennyviztisztito Telep helps minimize nutrient enrichment and protect downstream habitats, particularly in ecologically sensitive floodplain areas.
