CDA_ROSALIA Wastewater Treatment Plant, Vita, Sicily

CDA_ROSALIA is a wastewater treatment plant located in Vita, a town in the province of Trapani, Sicily, Italy. The plant serves a population of approximately 2,322 and has a designed capacity of 3,000 m³/day, with an average discharge volume of 459.67 m³/day. 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 of this size. Secondary treatment typically involves biological oxidation and sedimentation to remove organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the region's water resources and coastal environment from pollution.

The plant discharges into the local drainage basin in western Sicily, which flows into the Mediterranean Sea near the Gulf of Trapani. This coastal area supports diverse marine life and is important for local fisheries and tourism. Proper wastewater treatment helps prevent eutrophication and maintains water quality in the sensitive Mediterranean ecosystem.
