Overview
The LAVRIO wastewater treatment plant serves the community of Keratea in East Attica, Greece, with a population equivalent of 18,000. It is located near the Aegean Sea coast and operates under the EU Urban Waste Water Treatment Directive.
The LAVRIO wastewater treatment plant is situated in the Keratea municipal unit, part of the Lavreotiki municipality in East Attica, Greece. Serving a population equivalent of 18,000, the plant is a key component of the region's sanitation infrastructure, addressing the needs of this coastal area near the Aegean Sea. As a facility in Greece, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size (10,000-150,000 PE) discharging into coastal waters. The directive also requires appropriate treatment to protect sensitive areas, which may include nutrient removal if the receiving waters are designated as sensitive. The plant's treated effluent is discharged into the coastal waters of the Aegean Sea, a semi-enclosed sea with significant ecological importance. The region supports diverse marine life and is influenced by both local runoff and broader Mediterranean currents. Proper treatment is essential to prevent eutrophication and protect coastal ecosystems, including nearby beaches and fishing grounds.
Environmental context
The LAVRIO plant discharges into the Aegean Sea, a key water body that connects to the Mediterranean Sea. The coastal waters near Keratea support marine biodiversity, including fish populations and seagrass meadows. The area is also important for tourism and local fisheries, making effective wastewater treatment critical to maintaining water quality and preventing nutrient pollution.
