San Sosti Capano Wastewater Treatment Plant, Calabria, Italy

San Sosti Capano is an advanced wastewater treatment plant located in San Sosti, a town in the province of Cosenza, Calabria, Italy. The plant serves a population of 2,660 and has a designed capacity of 3,800 cubic meters per day, with an average discharge volume of 526.59 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. For a small agglomeration of this size, advanced treatment ensures compliance with stringent environmental standards. The treated effluent is discharged into local watercourses that flow toward the Tyrrhenian Sea, part of the wider Mediterranean basin. The plant plays a key role in protecting the region's water quality, supporting both local ecosystems and downstream marine environments.

The plant discharges into small streams that drain into the Tyrrhenian Sea near the Gulf of Policastro. This coastal area supports diverse marine life, including seagrass meadows and fish nurseries. The advanced treatment helps minimize nutrient loading, protecting the sensitive coastal ecosystem from eutrophication and maintaining water quality for tourism and fisheries.
