Depuratore di Folgaria Wastewater Treatment Plant, Folgaria, Trentino-Alto Adige

Depuratore di Folgaria is a municipal wastewater treatment plant located in Folgaria, in the Trentino-Alto Adige region of northern Italy. The plant serves a population of approximately 16,222 people, placing it in the medium agglomeration category under Italian and EU regulations. Situated in the Alpine foothills, the facility is part of the local infrastructure managed by the Magnifica Comunità degli Altipiani Cimbri. As an Italian plant serving over 10,000 population equivalent, Depuratore di Folgaria operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum standard. The plant's capacity and discharge volume are not disclosed, but typical plants of this scale in Italy are designed to handle flows from residential and small commercial sources. The treated effluent is discharged into local watercourses that drain into the Adige River basin, eventually reaching the Adriatic Sea. The plant plays a key role in protecting the region's mountain streams and downstream aquatic ecosystems from nutrient pollution and pathogens, supporting water quality in the Adige watershed.

The plant discharges into tributaries of the Adige River, which flows south through Trentino and Veneto before entering the Adriatic Sea near Chioggia. The Adige is Italy's second-longest river and supports diverse aquatic life, including fish species such as brown trout and grayling. The Alpine watershed is ecologically sensitive, with seasonal variations in flow and temperature that influence treatment requirements.
