PARENTI_GUGLIELMO Wastewater Treatment Plant, San Giovanni in Fiore, Calabria

PARENTI_GUGLIELMO is an advanced wastewater treatment plant located in the Rovale area of San Giovanni in Fiore, in the province of Cosenza, Calabria, Italy. The plant serves a small population of 315 residents, reflecting its role in a rural or small-town setting within the mountainous region of the Sila plateau. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. It operates at approximately 89% capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to provide appropriate treatment, and the advanced level here exceeds the minimum secondary treatment standard. The treated effluent is discharged into local watercourses that ultimately drain into the Ionian Sea via the Neto River basin. The surrounding Sila Massif is an ecologically sensitive area, supporting diverse aquatic life and serving as an important water source for the region. The plant's advanced treatment helps protect downstream water quality in this mountainous watershed.

The plant discharges into tributaries of the Neto River, which flows eastward into the Gulf of Taranto in the Ionian Sea. The Sila plateau is a high-altitude ecosystem with forests and lakes, providing habitat for endemic species. Advanced treatment ensures minimal nutrient loading, protecting the sensitive aquatic environment and downstream coastal waters.
