TRONZANO Wastewater Treatment Plant, Tronzano Vercellese, Piemonte

TRONZANO is a wastewater treatment plant located in Tronzano Vercellese, in the Piemonte region of Italy. It serves a population of approximately 3,000 residents, operating as a secondary treatment facility. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local watercourses. As a secondary treatment plant, TRONZANO provides biological treatment to remove organic matter and suspended solids, meeting the standards required under Italian and European regulations. The plant has a designed capacity of 3,000 cubic meters per day, with a current discharge volume of 705.28 cubic meters per day, indicating it operates well below its capacity. This scale of plant is typical for small agglomerations in Italy, where treatment requirements are aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). The treated wastewater from TRONZANO is discharged into the local drainage network, which ultimately feeds into the Po River basin. The Po River is the longest river in Italy and flows into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant plays a role in protecting the water quality of this important river system.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River supports a rich ecosystem, including fish species such as sturgeon and eel, and provides water for irrigation in the Po Valley. The secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in the Adriatic.
