DEPURATORE DI FONDO - Advanced Wastewater Treatment in Fondo, Trentino-Alto Adige

DEPURATORE DI FONDO is an advanced wastewater treatment plant located in Fondo, a town in the Trentino-Alto Adige region of northern Italy. The plant serves a population of approximately 3,284 residents and is part of the municipal infrastructure of Borgo d'Anaunia in the Val di Non valley. Its location in the Italian Alps places it in a sensitive mountainous environment where water quality protection is critical. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 10,000 m³/day, the facility is sized to accommodate population fluctuations, including seasonal tourism in the alpine region. The plant's discharge volume is reported at 665.91 m³/day, indicating it operates well below its design capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Adige River, Italy's second-longest river, flowing into the Adriatic Sea. The plant plays a key role in protecting the sensitive alpine streams and the downstream Adige ecosystem from nutrient pollution and other contaminants. Its advanced treatment ensures compliance with stringent Italian and EU standards for water quality in sensitive areas.

The plant discharges into the local stream network within the Val di Non, which feeds into the Noce River, a tributary of the Adige River. The Adige flows south through Trentino and Veneto before entering the Adriatic Sea near Chioggia. This alpine watershed supports diverse aquatic life, including brown trout and other cold-water species, and is an important resource for agriculture and drinking water. The advanced treatment helps minimize nutrient loading and protects the ecological integrity of these sensitive mountain streams.
