Nea Artaki Wastewater Treatment Plant, Chalkideon, Central Greece

The Nea Artaki wastewater treatment plant is located in the municipal unit of Nea Artaki, part of the municipality of Chalkideon in the region of Central Greece (Perifereia Stereas Elladas). The plant serves a population of approximately 9,746, classifying it as a small to medium agglomeration under Greek and EU regulations. Its location near the coast of Euboea places it within 50 km of the sea, influencing its discharge and environmental considerations. As a Greek facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to comply with these standards to protect the marine environment. The treated effluent from Nea Artaki is discharged into the South Euboean Gulf, a part of the Aegean Sea. This coastal area supports diverse marine life and is important for local fisheries and tourism. The plant's operation helps reduce nutrient and pollutant loads entering the gulf, contributing to the ecological health of the region and preventing eutrophication in the coastal waters.

The Nea Artaki plant discharges into the South Euboean Gulf, which connects to the Aegean Sea and ultimately the Mediterranean Sea. This coastal environment supports a variety of marine species and is used for fishing and recreation. The plant's effluent management is critical to preventing nutrient enrichment and maintaining water quality in this ecologically sensitive area.
