Depuratore di Calavino is an advanced wastewater treatment plant located in Vallelaghi, in the Trentino-Alto Adige region of northern Italy. The plant serves a population of approximately 5,357 people and has a designed capacity of 7,000 cubic meters per day, with an average discharge volume of 850.82 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italy requires advanced treatment for sensitive areas, and plants serving agglomerations of this scale typically meet secondary treatment standards, with advanced treatment applied where necessary to protect receiving waters. The plant discharges into the local watershed, which ultimately drains into the Adige River and then the Adriatic Sea. The region is known for its Alpine environment and sensitive aquatic ecosystems, making advanced treatment crucial for protecting water quality and biodiversity.

Environmental context

The plant discharges into the local watershed that feeds the Adige River, one of Italy's major rivers, which flows into the Adriatic Sea. The area is ecologically sensitive, supporting diverse aquatic life and serving as an important corridor for migratory species. Advanced treatment helps minimize nutrient loading and protects downstream water quality in the Adige basin.
