PARENTI_LA_POSTA Wastewater Treatment Plant, San Marco Argentano, Calabria

PARENTI_LA_POSTA is a wastewater treatment plant located in San Marco Argentano, in the province of Cosenza, Calabria, Italy. The plant serves a small population of 455 residents, reflecting its role in a rural or small-town setting within the region. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant operates well within its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea via the Crati River basin. The plant's advanced treatment helps protect the downstream aquatic environment, including the sensitive coastal ecosystems of the Ionian Sea, by reducing nutrient loads and pollutants.

The plant discharges into the local watershed that feeds the Crati River, one of the major rivers in Calabria, which flows into the Gulf of Taranto in the Ionian Sea. The downstream environment supports diverse aquatic life and is important for regional biodiversity. Advanced treatment at this plant helps minimize eutrophication risks and protects the ecological health of the river and coastal waters.
