Depuratore di Molina di Ledro - Advanced Wastewater Treatment in Biacesa di Ledro, Trentino-Alto Adige

Depuratore di Molina di Ledro is an advanced wastewater treatment plant located in Biacesa di Ledro, a frazione of the municipality of Ledro in Trentino-Alto Adige/Südtirol, Italy. The plant serves a population of approximately 2,841 people, reflecting its role in a small alpine community. It is situated in the scenic Valle di Ledro, near Lake Ledro, and operates under Italian national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 4,500 m³/day and a current discharge volume of 620.20 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As an advanced treatment plant, it meets stringent standards for sensitive areas, which are common in the Alpine region. The treated wastewater is discharged into the local watershed, which drains into Lake Ledro, a natural lake in the Sarca River basin. Lake Ledro is a popular tourist destination and supports diverse aquatic life. The Sarca River eventually flows into Lake Garda, one of Italy's largest and most ecologically significant lakes. The plant's advanced treatment helps protect these water bodies from eutrophication and pollution.

The plant discharges into the watershed of Lake Ledro, a glacial lake in the Italian Alps that feeds the Ponale River, which flows into Lake Garda. Lake Garda is a major subalpine lake with high ecological value, supporting diverse fish species and migratory birds. The advanced treatment at Depuratore di Molina di Ledro helps prevent nutrient loading and maintains water quality in this sensitive alpine ecosystem, which is important for tourism and biodiversity.
