Altomonte Contrada Corvocasello Wastewater Treatment Plant, Calabria, Italy

The Altomonte Contrada Corvocasello wastewater treatment plant is located in the municipality of Altomonte, in the province of Cosenza, Calabria, Italy. It serves a small population of 350 residents, reflecting its role in a rural or small-town setting. The plant is situated inland, more than 10 km from the coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a designed capacity of 600 m³/day and an actual discharge volume of 69.29 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variability. The advanced treatment level ensures high-quality effluent, reducing nutrient loads and protecting downstream water bodies. The treated wastewater is discharged into local watercourses that eventually drain into the Ionian Sea via the Crati River basin. The region's aquatic ecosystems benefit from the advanced treatment, which helps maintain water quality in a area known for its agricultural and natural landscapes. The plant's operation supports the environmental health of the Calabrian watershed.

The plant discharges into local streams that feed into the Crati River, one of the major rivers in Calabria, which flows into the Ionian Sea. The Ionian Sea is a semi-enclosed basin with sensitive marine ecosystems, including seagrass meadows and diverse fish populations. Advanced treatment at this plant helps minimize nutrient pollution, protecting downstream aquatic habitats and supporting the ecological balance of the coastal zone.
