Overview
Nea Moudania wastewater treatment plant serves the town of Nea Moudania in Central Macedonia, Greece. It is located near the Thermaic Gulf and operates under EU regulations.
The Nea Moudania wastewater treatment plant serves the town of Nea Moudania in the Chalkidiki region of Central Macedonia, Greece. The plant is designed to treat wastewater from a population of approximately 17,080 people, placing it in the medium agglomeration category under EU classification. 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's treated effluent is discharged into the Thermaic Gulf, a semi-enclosed embayment of the Aegean Sea. This coastal environment supports diverse marine life and is an important area for fisheries and tourism. Proper treatment is essential to protect water quality and ecological health in the gulf.
Environmental context
The plant discharges into the Thermaic Gulf, part of the Aegean Sea, which receives drainage from several rivers including the Axios and Aliakmonas. The gulf is ecologically sensitive, supporting seagrass meadows and important fish nursery grounds. Nutrient loading from wastewater can contribute to eutrophication, making effective treatment critical for preserving marine biodiversity and water quality.
