Depuratore di Ragoli Wastewater Treatment Plant, Tione di Trento, Trentino-Alto Adige

Depuratore di Ragoli is a municipal wastewater treatment plant located along SS237 in Tione di Trento, within the Comunità delle Giudicarie in the Trentino-Alto Adige region of northern Italy. The facility serves a population of approximately 16,678, placing it in the medium agglomeration category under EU regulations. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires appropriate treatment before discharge into sensitive areas, which are common in the Alpine region. Regulatory compliance ensures adequate treatment for the served population. The plant discharges treated wastewater into local watercourses that drain into the Sarca River, a major tributary of the Adige River. The Adige flows south through Trentino and Veneto before entering the Adriatic Sea near Chioggia. The surrounding Alpine watershed supports diverse aquatic life and is ecologically sensitive, requiring careful management of nutrient loads to protect downstream ecosystems.

The plant's treated effluent enters local streams that feed the Sarca River, which joins the Adige River near Trento. The Adige is the second-longest river in Italy, flowing through the Po Valley and into the Adriatic Sea. The Alpine watershed is characterized by high biodiversity, including salmonid fish species, and is sensitive to nutrient enrichment. Proper wastewater treatment is essential to maintain water quality in this ecologically important region.
