Amfissa Wastewater Treatment Plant, Central Greece | EU Regulatory Context

The Amfissa wastewater treatment plant is located in the municipal unit of Amfissa, within the municipality of Delphi, in the Phocis regional unit of Central Greece. Serving a population of approximately 6,909, the plant is part of the region's wastewater infrastructure managed under Greek national regulations aligned with EU directives. As a facility serving a medium agglomeration (between 2,000 and 10,000 population equivalent), the plant is required by the EU Urban Waste Water Treatment Directive (91/271/EEC) to provide secondary treatment. The designed capacity is reported as 1.00 (likely in thousand cubic meters per day or similar units), indicating a scale appropriate for the served population. The regulatory framework ensures compliance with European standards. The treated effluent from the Amfissa plant is discharged into the local watershed, which ultimately drains into the Gulf of Corinth via small coastal streams. The Gulf of Corinth is a semi-enclosed marine basin with significant ecological importance, supporting diverse marine life and serving as a migratory corridor for fish species. The plant's location within 50 km of the coast means its discharge can influence coastal water quality, necessitating effective treatment to protect the marine environment.

The Amfissa plant discharges into the local drainage network that flows into the Gulf of Corinth, a deep semi-enclosed basin connected to the Ionian Sea. The gulf supports diverse marine ecosystems, including seagrass meadows and fish spawning grounds. Effective wastewater treatment is critical to prevent nutrient enrichment and protect the ecological balance of this coastal environment.
