BARISCIANO Wastewater Treatment Plant, Barisciano, Italy

BARISCIANO is a municipal wastewater treatment plant located in Barisciano, a town in the province of L'Aquila, Abruzzo region, Italy. The facility serves a population of approximately 2,212 residents and is situated in an inland, mountainous area of central Italy. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. With a designed capacity of 1,500 m³/day and a current discharge volume of 437.90 m³/day, the plant operates well within its capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Aterno-Pescara river system. The plant plays a key role in protecting the water quality of the surrounding watershed, which supports diverse aquatic life and is part of the Apennine mountain ecosystem.

The plant discharges into local streams that feed into the Aterno River, which flows through the Abruzzo region and eventually reaches the Adriatic Sea near Pescara. The watershed supports a variety of aquatic species and is ecologically sensitive due to its mountainous terrain and proximity to the Gran Sasso e Monti della Laga National Park. Proper wastewater treatment is essential to prevent nutrient pollution and maintain the ecological balance of this important river basin.
