FORO Wastewater Treatment Plant, Ortona, Abruzzo, Italy

FORO is a wastewater treatment plant located in Ortona, in the Abruzzo region of Italy, along the Foro river. It serves a small population of approximately 2,000 residents, reflecting its role in managing local domestic wastewater in a coastal municipality. The plant is situated near the Adriatic Sea, within 10 km of the coastline, which places it in a sensitive coastal zone requiring careful discharge management. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the minimum requirement for discharges into coastal waters, and for agglomerations of this size (2,000 population equivalent), the directive mandates appropriate treatment. The plant's designed capacity is 2,000 cubic meters per day, matching the population served, and it reports a daily discharge volume of approximately 396 cubic meters. The treated effluent from FORO is discharged into the local water environment, ultimately reaching the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and diverse marine life. The plant's coastal location means its discharge must be managed to protect bathing waters and marine habitats, in line with Italian and EU environmental regulations. The Foro river itself supports local aquatic life and contributes to the regional hydrology of the Abruzzo coast.

FORO plant discharges treated wastewater into the Foro river, which flows into the Adriatic Sea near Ortona. The Adriatic Sea is a shallow, semi-enclosed basin with important fisheries and tourism. The coastal zone supports seagrass beds and migratory bird routes, making nutrient and pathogen control critical. The plant's secondary treatment reduces organic load and suspended solids, helping to protect downstream marine water quality.
