Serrastretta Migliuso Wastewater Treatment Plant, Serrastretta, Calabria

Serrastretta Migliuso is an advanced wastewater treatment plant located in the municipality of Serrastretta, in the Calabria region of southern Italy. The plant serves a small population of approximately 1,077 residents, reflecting its role in a rural or small-town setting. It is situated inland, more than 10 km from the coast, but within 50 km of the Tyrrhenian Sea. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 1,000 m³/day aligns with the population served, and the actual discharge volume of 213.21 m³/day indicates operational headroom. As an Italian facility, it operates under national regulations implementing the EU directive, with permits issued by regional environmental authorities. The treated effluent is discharged into local watercourses that drain toward the Tyrrhenian Sea. The surrounding area is characterized by the mountainous terrain of the Calabrian Apennines, and the plant helps protect downstream aquatic ecosystems from nutrient pollution. Advanced treatment ensures high removal of organic matter and nutrients, supporting water quality in the regional watershed.

The plant discharges into small streams that flow through the Calabrian countryside before reaching the Tyrrhenian Sea. This coastal region supports diverse marine life and is important for local fisheries. Advanced treatment reduces the risk of eutrophication in downstream waters, helping to preserve the ecological balance of the receiving environment.
