DP09700804_BELLANO_VIA_PER_COLICO Wastewater Treatment Plant, Bellano, Lombardy

DP09700804_BELLANO_VIA_PER_COLICO is a wastewater treatment plant located in Bellano, a town in the province of Lecco, Lombardy, Italy. The plant serves a population of approximately 7,783 people, placing it in the small-to-medium agglomeration category under EU classification. As a plant in Italy, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into sensitive areas, which may apply given the region's proximity to Lake Como. The plant's treated effluent is discharged into the local water system, which ultimately drains into Lake Como, a major subalpine lake in northern Italy. Lake Como is a significant ecological and recreational resource, supporting diverse aquatic life and serving as a water source for downstream communities.

The plant discharges into the local watershed that feeds Lake Como, a deep subalpine lake in the Po River basin. Lake Como is ecologically sensitive, supporting diverse fish species and aquatic vegetation. The lake's outflow, the Adda River, flows into the Po River and eventually the Adriatic Sea. Protecting water quality in this chain is critical for both local biodiversity and downstream ecosystems.
