DP01717301_S_ZENO_NAVIGLIO Wastewater Treatment Plant, San Zeno Naviglio, Lombardy

DP01717301_S_ZENO_NAVIGLIO is an advanced wastewater treatment plant located in San Zeno Naviglio, a municipality in the province of Brescia, Lombardy, Italy. The plant serves a population of approximately 4,754 residents and has a designed capacity of 4,000 cubic meters per day, with a discharge volume of 941.12 cubic meters per day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. Italy's regulatory framework under this directive mandates advanced treatment for agglomerations discharging into sensitive water bodies, which is typical for plants in the Po River basin. The plant's treated effluent is discharged into local waterways that ultimately drain into the Po River, which flows into the Adriatic Sea. The Po basin is a densely populated and agriculturally intensive region, making nutrient removal critical to prevent eutrophication in the Adriatic. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the Po River delta.

The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. The Po River delta is an ecologically sensitive area that supports diverse aquatic life and is an important migratory corridor for birds. Advanced treatment at this plant helps reduce nutrient loads that could otherwise contribute to algal blooms and hypoxia in the Adriatic.
