Feroleto Antico Dipodi Wastewater Treatment Plant, Calabria, Italy

Feroleto Antico Dipodi is a wastewater treatment plant located in the municipality of Feroleto Antico, in the Calabria region of southern Italy. The plant serves a small population of 656 residents, reflecting its role in a rural or small-town setting. It is situated near the coast, within 10 km of the Tyrrhenian Sea. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The designed capacity is 1000 m³/day, with a reported discharge volume of 129.87 m³/day, indicating the plant operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The coastal location means the plant's discharge can affect nearshore marine ecosystems, including seagrass beds and fish nurseries. The advanced treatment level helps minimize nutrient loading and protects the ecological health of the receiving coastal waters.

The plant discharges into a small coastal watershed in Calabria, with the treated effluent eventually reaching the Tyrrhenian Sea. This marine environment supports diverse aquatic life, including important fish species and benthic habitats. The advanced treatment process reduces nutrient pollution, which is critical for preventing eutrophication in the nearshore zone and maintaining water quality for recreational and ecological uses.
