DP01615001_ORIO_AL_SERIO Wastewater Treatment Plant, Azzano San Paolo, Italy

DP01615001_ORIO_AL_SERIO is an advanced wastewater treatment plant located in Azzano San Paolo, near Bergamo in the Lombardy region of northern Italy. The plant serves a population of approximately 4,000 people and is part of the region's municipal wastewater infrastructure. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,000 m³/day and a discharge volume of 789.09 m³/day, the plant operates well below its capacity. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The treated effluent is discharged into local water bodies that ultimately drain into the Po River basin and the Adriatic Sea. The plant plays a key role in protecting the region's water resources and supporting downstream ecosystems.

The plant discharges into the Po River basin, which flows eastward through northern Italy into the Adriatic Sea. The Po River delta is an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. Advanced treatment helps reduce nutrient loading, protecting downstream water quality and preventing eutrophication in the Adriatic.
