San Vincenzo La Costa Palazzello Wastewater Treatment Plant - Calabria, Italy

The San Vincenzo La Costa Palazzello wastewater treatment plant is located in San Vincenzo La Costa, a municipality in the province of Cosenza, Calabria, Italy. The plant serves a small population of 87 people, reflecting the rural character of the area. It is situated inland, more than 10 km from the coast, and operates under Italian national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. The designed capacity is 100 m³/day, and the current discharge volume is 17.22 m³/day, indicating that the plant operates well below its capacity. For small agglomerations under 2,000 population equivalent, the EU directive allows appropriate treatment, which may include primary treatment, depending on the receiving water body's sensitivity. The treated effluent is discharged into a local watercourse that ultimately flows into the Tyrrhenian Sea. The region's watershed supports diverse aquatic life and is part of the broader Mediterranean coastal ecosystem. The plant's operation helps protect local streams and downstream marine environments from untreated wastewater pollution.

The plant discharges into a local stream that flows through the Crati River basin and eventually reaches the Tyrrhenian Sea near the Gulf of Sant'Eufemia. This coastal area supports ecologically sensitive habitats, including seagrass meadows and marine biodiversity. The inland location reduces direct marine impact, but the receiving water body is part of a watershed that requires careful management to prevent nutrient enrichment and protect downstream ecosystems.
