LAGO_CENTRO Wastewater Treatment Plant, Orsomarso, Calabria, Italy

LAGO_CENTRO is an advanced wastewater treatment plant located in Orsomarso, in the province of Cosenza, Calabria, Italy. It serves a population of approximately 1,500 people and has a designed capacity of 2,300 cubic meters per day, with an actual discharge volume of 296.95 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 discharges into sensitive areas. For a small agglomeration of this size, the directive mandates at least secondary treatment, and the plant's advanced level exceeds this requirement. The treated effluent is discharged into local watercourses that flow toward the Tyrrhenian Sea. The surrounding region of Calabria features a rugged coastline and diverse aquatic habitats. The plant's advanced treatment helps protect downstream water quality and supports the ecological health of the receiving waters.

The plant discharges into local streams that drain into the Tyrrhenian Sea, a key basin of the Mediterranean Sea. The coastal waters of Calabria support diverse marine life, including seagrass meadows and fish populations. Advanced treatment reduces nutrient loading, which helps prevent eutrophication and maintains water quality for both aquatic ecosystems and recreational use.
