Letenye Szennyviztisztito Telep - Advanced Wastewater Treatment in Letenye, Hungary

Letenye Szennyviztisztito Telep is an advanced wastewater treatment plant located in Letenye, a town in Zala County, Hungary. The facility serves a population of approximately 4,348 people, making it a small-scale municipal treatment plant. It is situated in the Nyugat-Dunántúl region, near the border with Croatia. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,450 m³/day and an average discharge volume of 512.55 m³/day, the plant operates well below its capacity, indicating room for future growth. As a Hungarian facility, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local water bodies that eventually drain into the Mura River, a tributary of the Drava, which flows into the Danube and ultimately the Black Sea. The plant plays a key role in protecting the local watershed and downstream ecosystems, including the Drava River basin, which supports diverse aquatic life and is an important ecological corridor in Central Europe.

The plant discharges into the local drainage network that feeds the Mura River, a tributary of the Drava River. The Drava flows into the Danube, which empties into the Black Sea. This watershed supports diverse aquatic habitats and is part of a significant ecological corridor in Central Europe. The advanced treatment level helps minimize nutrient loading and protects downstream water quality in this sensitive transboundary river system.
