CDA_FAVARELLA Wastewater Treatment Plant, Salemi, Sicily

CDA_FAVARELLA is a municipal wastewater treatment plant located in Salemi, a town in the province of Trapani, Sicily, Italy. The plant serves a population equivalent of 3,314 and has a designed capacity of 7,000 m³/day, indicating it operates below its full capacity. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards. Treated wastewater from the plant is discharged into the local water environment, ultimately draining into the Mediterranean Sea via the surrounding watershed. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream water bodies.

The plant discharges into local watercourses that flow through the Sicilian landscape and eventually reach the Mediterranean Sea. The region's watershed supports diverse aquatic life and is important for coastal ecosystems. Proper treatment helps prevent nutrient pollution and protects marine habitats.
