DP01603401_BOTTANUCO Wastewater Treatment Plant, Bottanuco, Lombardia

DP01603401_BOTTANUCO is an advanced wastewater treatment plant located in Bottanuco, a town in the province of Bergamo, Lombardia, Italy. The plant serves a population of approximately 4,935 people and has a designed capacity of 5,000 m³/day, with an actual discharge volume of 976.96 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size (under 10,000 population equivalent) are generally required to provide secondary treatment, but the advanced level here indicates a higher standard likely driven by local environmental sensitivity. The treated effluent is discharged into the local water system, which ultimately drains into the Adda River and then into the Po River, the longest river in Italy. The Po River flows into the Adriatic Sea, supporting diverse aquatic life and important ecosystems in the Po Delta. The advanced treatment helps protect these downstream environments from nutrient pollution.

The plant discharges into the local water network that feeds into the Adda River, a tributary of the Po River. The Po River basin is one of the most agriculturally and industrially productive regions in Italy, and its waters flow into the Adriatic Sea. The advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing eutrophication in the sensitive coastal and delta ecosystems of the Po River.
