DP01303801_CAGNO Wastewater Treatment Plant, Solbiate con Cagno, Lombardy

DP01303801_CAGNO is a wastewater treatment plant located in Solbiate con Cagno, a municipality in the province of Como, Lombardy, Italy. The plant serves a population of approximately 7,500 residents, placing it in the small-to-medium agglomeration category under Italian and EU regulations. As a plant serving fewer than 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. Italian plants of this scale typically employ secondary biological treatment to meet national water quality standards. The plant discharges treated effluent into local watercourses that drain into the Po River basin, eventually reaching the Adriatic Sea. Its operation supports the protection of local streams and groundwater resources in the densely populated Lombardy region, helping to maintain water quality for downstream communities and ecosystems.

The plant is located in the Po River basin, one of Italy's most important watersheds. Treated effluent from the plant flows into local tributaries that eventually reach the Po River and then the Adriatic Sea. The region supports diverse aquatic life and is an important agricultural area, making effective wastewater treatment critical for preventing nutrient pollution and protecting downstream water quality.
