PORTIGLIOLA_ARDORE_VESCOVATO Wastewater Treatment Plant, Careri, Calabria

PORTIGLIOLA_ARDORE_VESCOVATO is a municipal wastewater treatment plant located in Careri, in the Calabria region of southern Italy. The plant serves a population of 2,150 and operates with 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. The facility has a designed capacity of 3,500 m³/day and currently discharges an average of 425.62 m³/day of treated effluent. As a secondary treatment plant, it employs biological processes to reduce organic matter and suspended solids, meeting the EU directive's requirements for inland and coastal discharges. The plant's capacity utilization is low, indicating ample headroom for future growth or seasonal variations. The regulatory framework for this plant is governed by Italian national legislation transposing the EU directive, with oversight from regional environmental authorities in Calabria. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea. The coastal location within 10 km of the shoreline means the discharge may affect nearshore marine water quality. The receiving water body supports diverse aquatic life and is part of the broader Mediterranean coastal ecosystem, which is sensitive to nutrient inputs from wastewater.

The plant discharges into a local watercourse that flows toward the Ionian Sea, a semi-enclosed basin of the Mediterranean. The coastal waters near Careri support marine biodiversity, including seagrass meadows and fish spawning grounds. Nutrient and pathogen loads from treated effluent, even at secondary treatment levels, can influence local water quality and ecosystem health, particularly in a region with tourism and fisheries.
