Overview
KILKIS wastewater treatment plant serves the city of Kilkis in Central Macedonia, Greece, with a population equivalent of 26,000. It operates under the EU Urban Waste Water Treatment Directive.
The KILKIS wastewater treatment plant is located in Kilkis, a city in the Central Macedonia region of northern Greece. The plant serves a population equivalent of 26,000, classifying it as a medium-sized agglomeration under EU regulations. Its location inland, approximately 50 km from the coast, influences its discharge and treatment requirements. As a Greek facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these EU standards to protect local water quality. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Aegean Sea. The region's watershed supports agricultural activities and diverse aquatic habitats. Proper treatment is essential to prevent nutrient pollution and safeguard downstream ecosystems, including the coastal waters of the Thermaic Gulf.
Environmental context
The plant discharges into local streams that flow into the Axios River basin, which ultimately drains into the Thermaic Gulf of the Aegean Sea. This coastal area supports important fisheries and migratory bird populations. Effective nutrient removal is critical to prevent eutrophication in the gulf, which is a semi-enclosed basin sensitive to pollution from agricultural and urban runoff.
