AGNONE_FOSSATO_PISCIARIELLO Wastewater Treatment Plant, Agnone, Molise, Italy

AGNONE_FOSSATO_PISCIARIELLO is a wastewater treatment plant located in Agnone, a town in the province of Isernia, Molise, Italy. The plant serves a population of approximately 5,376 people, classifying it as a small agglomeration under EU regulations. As an Italian facility, it operates within the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries for agglomerations of this size. The plant's treatment process and capacity are consistent with standards expected for small inland communities. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea via the Trigno River. The plant plays a key role in protecting the water quality of the Trigno basin and downstream coastal ecosystems.

The plant discharges into the Trigno River basin, which flows eastward through Molise and Abruzzo before entering the Adriatic Sea near Vasto. The Trigno River supports diverse aquatic life and is an important water resource for agriculture and local communities. The Adriatic Sea receives the river's flow, contributing to the nutrient balance of the coastal marine environment.
