Portigliola Ardore San Nicola Wastewater Treatment Plant, Careri, Calabria

Portigliola Ardore San Nicola is a wastewater treatment plant located in Careri, within the province of Reggio Calabria in the Calabria region of southern Italy. The plant serves a small population of 400 people, reflecting its role in a rural or small-town setting. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Its designed capacity is 600 cubic meters per day, with an average discharge volume of 79.19 cubic meters per day, indicating it operates well below capacity. The plant falls under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The treated effluent is discharged into the local watershed, which drains toward the Ionian Sea. The coastal location within 10 km of the sea means the discharge may influence nearshore water quality. The area supports diverse marine life and is part of the broader Mediterranean ecosystem, where nutrient management is important to prevent eutrophication.

The plant discharges into a local watercourse that flows to the Ionian Sea, a key basin of the Mediterranean Sea. The coastal waters in this region support diverse aquatic life, including fish nurseries and migratory species. As a secondary treatment plant near the coast, its nutrient and pollutant loads are relevant to the health of the nearshore marine environment, where careful management helps prevent algal blooms and oxygen depletion.
