Sant'Onofrio Scapalegga Wastewater Treatment Plant, Calabria, Italy

The Sant'Onofrio Scapalegga wastewater treatment plant is located in Sant'Onofrio, a municipality in the province of Vibo Valentia, Calabria, Italy. The plant serves a population of 4,541 and has a designed capacity of 6,000 cubic meters per day, with an average discharge volume of 898.96 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive areas. The plant's inland location suggests it discharges into a local stream or river within the Calabrian watershed. The treated effluent from the plant ultimately drains into the Tyrrhenian Sea via the local hydrographic network. Calabria's rivers are typically short and steep, flowing from the Apennine mountains to the coast. The plant's advanced treatment helps protect downstream aquatic ecosystems and coastal water quality, supporting biodiversity in the region's Mediterranean habitats.

The plant discharges into a local watercourse that flows through the Calabrian region and eventually reaches the Tyrrhenian Sea. The downstream environment includes small rivers and streams that support diverse aquatic life, including endemic fish species. The advanced treatment level reduces nutrient loading, which is critical for preventing eutrophication in coastal waters and maintaining the ecological health of the Tyrrhenian Sea's marine habitats.
