ORSOGNA_ZONA_INDUSTRIALE Wastewater Treatment Plant, Ortona, Italy

ORSOGNA_ZONA_INDUSTRIALE is a wastewater treatment plant located in the Fonte Grande area of Ortona, in the province of Chieti, Abruzzo, Italy. The plant serves a population of approximately 800 people and is situated in an industrial zone near the Adriatic coast. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent of less than 10,000. The designed capacity is 2,800 m³/day, and the current discharge volume is 158.37 m³/day, indicating a utilization rate well below capacity. The treated effluent is discharged into the local environment, ultimately reaching the Adriatic Sea. The plant's proximity to the coast (within 10 km) means its discharge can affect coastal water quality. The region supports diverse marine life and is part of the Adriatic basin, which is ecologically sensitive.

The plant discharges into the Adriatic Sea via local watercourses. The Adriatic Sea is a semi-enclosed basin with limited water exchange, making it sensitive to nutrient inputs. The coastal area near Ortona supports seagrass meadows and fish nurseries, which can be impacted by nutrient loading from wastewater. The plant's secondary treatment reduces organic matter but may not fully remove nutrients, posing a risk of eutrophication in the coastal zone.
