Overview
ORESTIADA wastewater treatment plant serves the city of Orestiada in Eastern Macedonia and Thrace, Greece, with a population of approximately 24,000. The plant operates under EU Urban Waste Water Treatment Directive 91/271/EEC.
The ORESTIADA wastewater treatment plant is located in Orestiada, a city in the Evros regional unit of Eastern Macedonia and Thrace, Greece. It serves a population of about 24,000, classifying it as a medium agglomeration under EU standards. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure. Under the EU Urban Waste Water Treatment Directive 91/271/EEC, agglomerations of this size are required to provide secondary treatment or equivalent. The plant is expected to comply with Greek national regulations that transpose the directive. It plays a key role in managing municipal wastewater for the area. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Evros River (also known as the Maritsa). The Evros River flows into the Aegean Sea, forming a delta that supports diverse aquatic life and is an important ecological corridor. The plant's operations help protect downstream water quality and the sensitive ecosystems of the Evros delta.
Environmental context
The ORESTIADA plant discharges into the Evros River basin, which flows through Greece and Turkey before reaching the Aegean Sea. The Evros delta is a vital wetland that supports migratory birds and diverse aquatic species. The plant's treatment processes help maintain water quality in this ecologically sensitive area, reducing nutrient and pollutant loads that could impact the downstream marine environment.
