Overview
The LEFKADA wastewater treatment plant serves the municipal unit of Lefkada in the Ionian Islands region of Greece, treating wastewater for approximately 11,500 residents.
The LEFKADA wastewater treatment plant is located in Kalligoni, within the municipal unit of Lefkada, on the island of Lefkada in the Ionian Islands region of Greece. The plant serves a population of around 11,500 people, representing a medium-sized agglomeration under Greek and EU regulatory frameworks. 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 plant's treated effluent is discharged into the Ionian Sea, a sensitive marine environment that supports diverse aquatic life and important fisheries. The surrounding watershed includes the island's coastal areas and seasonal streams that drain into the sea, making proper treatment essential for protecting local water quality and marine ecosystems.
Environmental context
The LEFKADA plant discharges into the Ionian Sea, a deep marine basin connected to the Adriatic and Mediterranean Seas. The coastal waters around Lefkada support seagrass meadows, coral habitats, and migratory fish species. As a Mediterranean island, the local watershed is characterized by karst geology and seasonal rainfall, making groundwater and coastal water quality particularly sensitive to nutrient inputs from wastewater.
Frequently asked questions
The LEFKADA plant is located in Kalligoni, within the municipal unit of Lefkada, on the island of Lefkada in the Ionian Islands region of Greece.
The plant serves approximately 11,500 people, classifying it as a medium-sized agglomeration under EU wastewater treatment directives.
The plant discharges treated effluent into the Ionian Sea, a coastal marine environment. Coastal plants typically use submarine outfalls.
As a Greek facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 10,000 population equivalent discharging into coastal waters.
Under the EU UWWTD, plants serving 10,000-150,000 population equivalent in coastal areas typically require secondary treatment (biological treatment with settling). Some may also include nutrient removal if discharging into sensitive areas.
