CDA_KARBINARUSA Wastewater Treatment Plant, Salemi, Sicily

CDA_KARBINARUSA is a wastewater treatment plant located in Carmine, Salemi, in the province of Trapani, Sicily, Italy. The plant serves a population of approximately 1,240 people and has a designed capacity of 1,500 cubic meters per day, with a current discharge volume of 245.48 cubic meters per 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. For populations under 2,000, secondary treatment is typically sufficient to meet environmental standards, though sensitive areas may require additional nutrient removal. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. Sicily's Mediterranean climate and coastal ecosystems make proper wastewater treatment essential to protect marine water quality and biodiversity. The plant's inland location reduces direct coastal impact, but its discharge still affects downstream water bodies.

The plant discharges into a local watercourse that flows through the Salemi area, part of the drainage basin of the Mediterranean Sea. The region's watershed supports diverse aquatic life and is important for agricultural irrigation. Proper treatment helps prevent nutrient pollution and protects downstream coastal ecosystems, including seagrass meadows and marine habitats.
