Overview
Metamorphosi wastewater treatment plant serves the northern sector of Athens, Greece, with a population equivalent of 450,000. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards.
The Metamorphosi wastewater treatment plant is located in the municipality of Metamorphosi, in the North Athens regional unit of Attica, Greece. Serving a population equivalent of 450,000, it is a major facility within the greater Athens metropolitan area, managing municipal wastewater from a densely populated urban region. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide at least secondary treatment, with more stringent tertiary treatment if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating its substantial scale. The regulatory framework ensures that the plant meets European standards for effluent quality. The treated effluent is discharged into the local water system, ultimately reaching the Saronic Gulf, a part of the Aegean Sea. This coastal discharge requires careful management to protect marine ecosystems and recreational waters. The plant plays a critical role in safeguarding the environmental health of the Athens coastline and the broader Mediterranean Sea.
Environmental context
The plant discharges into the Saronic Gulf via local streams, which flows into the Aegean Sea. This coastal area supports diverse marine life and is important for tourism and fisheries. The plant's operations help prevent nutrient pollution and protect water quality in this ecologically sensitive region.
