DEPURATORE DI CASTELLO TESINO - Advanced Wastewater Treatment in Castello Tesino, Italy

DEPURATORE DI CASTELLO TESINO is a wastewater treatment facility located in Castello Tesino, within the Trentino-Alto Adige region of northern Italy. The plant serves a population of approximately 5,624 residents and is situated in the alpine valley of Valsugana, near the Brenta River basin. The plant provides advanced treatment, which goes 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 7,500 m³/day and an average discharge volume of 974.18 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local watercourses that eventually feed into the Brenta River, which flows southward to the Adriatic Sea. The advanced treatment helps protect the sensitive alpine aquatic ecosystems and downstream water quality in the Po River basin.

The plant discharges into the Brenta River watershed, which flows through the Valsugana valley and ultimately reaches the Adriatic Sea near Venice. The region features sensitive alpine streams that support diverse aquatic life, including native fish species. Advanced treatment helps minimize nutrient loading and protects downstream ecosystems in the Po River delta.
