Caggiano Impianto Località Varco della Mole - Advanced Wastewater Treatment in Caggiano, Campania

Caggiano Impianto Località Varco della Mole is an advanced wastewater treatment plant located in Caggiano, a town in the province of Salerno, Campania, Italy. The plant serves a population of approximately 2,550 residents, reflecting its role in managing municipal wastewater for this small community in southern Italy. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 3,500 m³/day and a current discharge volume of 504.81 m³/day, the facility operates well within its capacity. As an Italian plant, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and the sensitivity of receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Tyrrhenian Sea via the Sele River basin. The region's aquatic ecosystems benefit from the advanced treatment, which helps protect water quality in the downstream environment, supporting biodiversity and reducing nutrient loading in coastal waters.

The plant discharges into local streams that feed into the Sele River, which flows into the Tyrrhenian Sea near Paestum. This coastal area supports diverse marine life and is ecologically sensitive due to its proximity to important seagrass meadows and fish nursery habitats. Advanced treatment helps minimize nutrient pollution, protecting the downstream marine environment from eutrophication.
