BAGNOLI_DEL_TRIGNO_VALLONE_LA_TERRA Wastewater Treatment Plant, Bagnoli del Trigno, Italy

BAGNOLI_DEL_TRIGNO_VALLONE_LA_TERRA is an advanced wastewater treatment plant located in Bagnoli del Trigno, a town in the province of Isernia, Molise, Italy. The plant serves a population of approximately 2,357 residents, reflecting its role in managing domestic wastewater for this small agglomeration. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,195 cubic meters per day and a current discharge volume of about 466.6 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local watercourses that eventually drain into the Adriatic Sea via the Trigno River basin. The plant's advanced treatment helps protect the downstream aquatic environment, supporting water quality in the region's rivers and coastal areas. The facility contributes to the ecological health of the Molise region by reducing nutrient loads and preventing eutrophication in sensitive water bodies.

The plant discharges into local streams that flow into the Trigno River, which runs through Molise and enters the Adriatic Sea near the town of San Salvo. The Trigno River supports diverse aquatic life and is an important water resource for agriculture and ecosystems in the region. Advanced treatment at this plant helps minimize nutrient pollution, protecting the river's ecological balance and the coastal waters of the Adriatic Sea from eutrophication.
