Overview
SOUFLI wastewater treatment plant in Evros, Greece, serves about 3,900 people with advanced treatment. It discharges 429.15 m³/day and has a designed capacity of 9,650 m³/day.
SOUFLI is a wastewater treatment plant located in the Evros regional unit of Eastern Macedonia and Thrace, Greece. It serves a population of approximately 3,887 people, placing it in the small agglomeration category under EU regulations. The plant is situated near the town of Soufli, within the broader region of East Macedonia and Thrace. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 9,650 m³/day, while current discharge volume is 429.15 m³/day, indicating significant spare capacity. As a Greek facility, it operates under national regulations that transpose the EU directive, with permits issued by the Hellenic Ministry of Environment and Energy. The treated effluent is discharged into the local watershed, which ultimately drains into the Evros River (also known as the Maritsa River). The Evros River forms the border between Greece and Turkey and flows into the Aegean Sea. This river supports diverse aquatic life and is an important migratory corridor for birds. The advanced treatment helps protect the river's ecological health and downstream coastal waters.
Environmental context
The plant discharges into the Evros River basin, which flows into the Aegean Sea. The Evros River is a major transboundary watercourse supporting diverse aquatic ecosystems and serving as a critical habitat for migratory birds. Advanced treatment at the plant reduces nutrient and pollutant loads, helping to maintain water quality in this ecologically sensitive river and its delta.
