LUZZARA Wastewater Treatment Plant, Luzzara, Emilia-Romagna, Italy

LUZZARA is a wastewater treatment plant located in Luzzara, a town in the Emilia-Romagna region of northern Italy. The plant serves a population of about 4,395 people, placing it in the small agglomeration category under EU classification. As a small-scale facility in Italy, LUZZARA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. Italian regulations typically mandate secondary biological treatment for such communities. The plant discharges treated effluent into local watercourses that ultimately drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward through the Po Valley and empties into the Adriatic Sea, supporting diverse aquatic life and agricultural activities along its course.

The plant's treated effluent enters local tributaries of the Po River, which flows through the fertile Po Valley and discharges into the Adriatic Sea. This watershed supports significant biodiversity, including fish species such as sturgeon and eels, and provides irrigation for extensive agriculture. The Po Delta is an ecologically sensitive area with important wetland habitats.
