SEPINO_MACCHIE Wastewater Treatment Plant, Sepino, Molise, Italy

SEPINO_MACCHIE is an advanced wastewater treatment plant located in Sepino, in the Molise region of Italy. The facility serves a population of approximately 3,788 people, making it a small-scale municipal treatment plant. It is situated near the Tratturo Pescasseroli-Candela, a historic sheep track, in the Piana D'Olmo area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. It has a designed capacity of 3,900 m³/day and currently discharges a daily volume of about 750 m³. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into local watercourses that eventually drain into the Adriatic Sea. The plant plays a key role in protecting the water quality of the region's rivers and the downstream marine environment, supporting aquatic life and reducing nutrient pollution.

The plant discharges into local streams that flow through the Molise region and ultimately reach the Adriatic Sea. This coastal environment supports diverse marine life, including fish and crustaceans, and is important for local fisheries. Advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in the Adriatic's sensitive coastal zones.
