Capracotta Wastewater Treatment Plant, Capracotta, Molise, Italy

The Capracotta wastewater treatment plant is located in the town of Capracotta, in the province of Isernia, Molise region, Italy. It serves a population of about 5,000 residents, reflecting a small to medium agglomeration typical of inland Italian towns. The plant is situated in the Apennine mountains, an area characterized by rugged terrain and seasonal climate variations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The designed capacity is 5,093 cubic meters per day, with an actual discharge volume of 986.46 cubic meters per day, indicating operational headroom. The treated effluent is discharged into local streams that eventually feed into the Adriatic Sea via the Trigno or Biferno river basins. The mountainous setting means the receiving waters are likely sensitive to nutrient loading, making advanced treatment crucial for preserving downstream aquatic ecosystems and water quality in the Adriatic coastal zone.

The plant discharges into small mountain streams that drain into the Trigno or Biferno rivers, which flow eastward to the Adriatic Sea. The watershed supports diverse aquatic life and is part of a region known for its biodiversity. Advanced treatment helps minimize nutrient pollution, protecting downstream habitats and the coastal marine environment from eutrophication.
