Overview
YANNITSA wastewater treatment plant serves the city of Giannitsa in Central Macedonia, Greece. It is designed for a capacity of 1.00 and serves a population of 28,235.
The YANNITSA wastewater treatment plant is located in Giannitsa, a city in the Pella regional unit of Central Macedonia, Greece. The facility serves a population of approximately 28,235, classifying it as a medium-sized agglomeration under Greek and EU regulations. The plant is situated inland, away from the coast, and its operations are part of the regional wastewater infrastructure managed by the municipality. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this scale (between 10,000 and 100,000 population equivalent) are required to provide secondary treatment as a minimum. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant is expected to comply with these EU standards to protect local water quality. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Axios River basin and then into the Thermaic Gulf of the Aegean Sea. This water body supports diverse aquatic life and is important for regional agriculture and fisheries. Proper treatment is essential to prevent nutrient pollution and maintain the ecological health of the downstream environment.
Environmental context
The YANNITSA plant discharges into the local watershed that flows into the Axios River, a major river in northern Greece, and eventually reaches the Thermaic Gulf in the Aegean Sea. This coastal gulf is ecologically sensitive, supporting diverse marine life and important fisheries. The region's agricultural activities also rely on the river for irrigation, making nutrient removal from wastewater critical to prevent eutrophication and protect both freshwater and marine ecosystems.
