San Demetrio Corone San Nicola Wastewater Treatment Plant, Calabria, Italy

The San Demetrio Corone San Nicola wastewater treatment plant is located in San Demetrio Corone, a town in the Calabria region of southern Italy. The plant serves a small population of 410 residents, reflecting its role in a rural or small-scale community. Its location along Strada Provinciale 177 places it within the municipal area of Corigliano-Rossano. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent. This level of treatment indicates a commitment to high effluent quality, likely to protect sensitive receiving waters. The designed capacity is 500 cubic meters per day, with a current discharge volume of 81.17 cubic meters per day, suggesting ample capacity for future growth. The treated wastewater is discharged into the local environment within 10 km of the Ionian Sea coast. This proximity to the sea means the plant's effluent can influence coastal water quality and marine ecosystems. The plant's advanced treatment helps minimize nutrient and pollutant loads, supporting the ecological health of the downstream coastal zone, which is part of the broader Ionian Sea basin.

The plant discharges into a small watercourse that flows toward the Ionian Sea, a major basin of the Mediterranean Sea. The coastal area supports diverse marine life, including seagrass meadows and fish spawning grounds. Advanced treatment reduces the risk of eutrophication and protects sensitive coastal habitats from nutrient enrichment.
