TRESIGALLO_NUOVO Wastewater Treatment Plant, Tresigallo, Emilia-Romagna

TRESIGALLO_NUOVO is a wastewater treatment plant located in Tresigallo, a town in the Emilia-Romagna region of northern Italy. The plant serves a population of about 8,038 residents, classifying it as a small to medium agglomeration under EU regulations. It operates within the Unione Terre e Fiumi administrative area, near Ferrara. As an Italian plant serving fewer than 10,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. The directive mandates secondary treatment for inland freshwater discharges from agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest scale. The plant's treated effluent is discharged into local watercourses that drain into the Po River basin, one of Italy's most significant watersheds. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation. The Emilia-Romagna region is known for its intensive agriculture and industrial activity, making proper wastewater treatment crucial for protecting downstream ecosystems and water quality.

The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. This watershed supports extensive agriculture, including rice paddies and fruit orchards, and provides habitat for fish species such as sturgeon and eels. The Po Delta is a critical wetland area for migratory birds. Effective treatment helps prevent nutrient pollution that could cause eutrophication in the Adriatic, a semi-enclosed sea sensitive to algal blooms.
