SERRASTRETTA_COSTA Wastewater Treatment Plant, Serrastretta, Calabria, Italy

SERRASTRETTA_COSTA is an advanced wastewater treatment plant located in Serrastretta, in the province of Catanzaro, Calabria, Italy. The plant serves a small population of 1,077 residents, reflecting its role in a rural or small-town setting within the region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,000 m³/day and a discharge volume of 213.21 m³/day, the facility operates well within its capacity. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Tyrrhenian Sea or Ionian Sea, depending on the local watershed. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the environmental quality of Calabria's coastal waters.

The plant discharges into local streams that flow toward the Tyrrhenian or Ionian Sea, both of which are ecologically sensitive marine environments supporting diverse aquatic life and important fisheries. The advanced treatment level ensures reduced nutrient loading, helping to prevent eutrophication in downstream coastal waters.
