The Kallithea Chalkidikis wastewater treatment plant is located in the Kassandra municipal unit of Chalkidiki, Central Macedonia, Greece. It serves a population of around 11,500 people, placing it in the medium-agglomeration category under EU regulations. The plant is situated in a coastal tourist region, which influences its operational demands during peak seasons. As a Greek facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent (PE) discharging into coastal waters. The designed capacity is reported as 1.00 (likely in thousands of cubic meters per day), indicating a moderate-scale infrastructure. The regulatory framework ensures compliance with European standards. The plant's treated effluent is discharged into the Thermaic Gulf, part of the Aegean Sea. This coastal environment supports diverse marine life and is important for local fisheries and tourism. The region's karstic geology and seasonal population fluctuations pose challenges for consistent wastewater management. The plant plays a key role in protecting the coastal waters of the Kassandra peninsula from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Thermaic Gulf, a semi-enclosed basin of the Aegean Sea. This coastal area supports seagrass meadows and is a spawning ground for commercial fish species. The gulf receives freshwater inputs from several rivers, but the Kassandra peninsula relies on groundwater and coastal runoff. Protecting water quality is critical for maintaining the ecological health of the gulf and supporting the region's tourism-driven economy.
Frequently asked questions
The plant is located in the Kassandra municipal unit of Chalkidiki, Central Macedonia, Greece, near the town of Kassandreia.
The plant serves approximately 11,500 people, making it a medium-sized agglomeration under EU classification.
The treated effluent is discharged into the Thermaic Gulf, a coastal water body of the Aegean Sea, which is sensitive to nutrient inputs.
As a Greek facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 10,000 PE discharging into coastal waters.
Under the EU UWWTD, plants serving 10,000-150,000 PE in coastal areas must provide secondary treatment. Many Greek plants also incorporate nutrient removal to protect the oligotrophic Aegean Sea.
