Overview
The Xanthi wastewater treatment plant serves approximately 70,000 people in Diomedeia, Greece. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Xanthi wastewater treatment plant is located in Diomedeia, a settlement in the municipality of Avdira, within the regional unit of Xanthi in Eastern Macedonia and Thrace, Greece. The plant serves an estimated population of 70,000, classifying it as a large agglomeration under EU regulations. As a facility in an EU member state, the plant is subject to the Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for discharges into freshwater and estuaries from agglomerations of this size. The designed capacity is reported as 1. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Aegean Sea via the Nestos River basin. The region supports diverse aquatic life and is an important ecological corridor for migratory birds. The plant plays a key role in protecting downstream water quality and the coastal environment.
Environmental context
The Xanthi plant discharges into the Nestos River basin, which flows through the Rhodope Mountains and the Nestos Delta before entering the Aegean Sea. The delta is an ecologically sensitive area that supports diverse aquatic life and serves as an important migratory corridor for birds. The plant's operations help protect the downstream coastal waters and the broader marine ecosystem of the northern Aegean.
