TORANO CASTELLO CUPINI Wastewater Treatment Plant, Santa Maria le Grotte, Calabria

The TORANO CASTELLO CUPINI wastewater treatment plant is located in Santa Maria le Grotte, a locality in the municipality of San Martino di Finita, in the province of Cosenza, Calabria, Italy. This facility serves a population of approximately 1,500 people, placing it in the small-agglomeration category under Italian and EU regulations. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,100 m³/day and an actual discharge volume of 296.95 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Tyrrhenian Sea. The plant's location in the Calabria region, characterized by mountainous terrain and a Mediterranean climate, means that the receiving waters support diverse aquatic life and are important for local agriculture and tourism. The advanced treatment helps protect downstream ecosystems and coastal water quality.

The plant discharges treated wastewater into local streams that flow toward the Tyrrhenian Sea, a key water body for the region's ecology and economy. The downstream environment includes coastal areas that support marine biodiversity and are used for recreation and fishing. Advanced treatment reduces nutrient loads and pollutants, helping to prevent eutrophication and protect sensitive coastal habitats.
