DP01405601_ROGOLO Wastewater Treatment Plant, Andalo Valtellino, Lombardy

DP01405601_ROGOLO is a wastewater treatment plant located in Andalo Valtellino, within the province of Sondrio in Lombardy, Italy. The plant serves a population of approximately 15,000 people, placing it in the medium agglomeration category under European Union regulations. 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 more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with European standards. The plant discharges into the local watershed, which ultimately drains into the Adda River and then into Lake Como, a major subalpine lake. The downstream environment supports diverse aquatic life and is important for regional water quality and tourism. The plant plays a key role in protecting these water bodies from pollution.

The plant's treated effluent flows into the Adda River, which is a tributary of Lake Como, one of Italy's largest and most ecologically significant subalpine lakes. Lake Como supports a rich ecosystem of fish and aquatic plants and is a vital resource for recreation and drinking water. The surrounding watershed is characterized by mountainous terrain and seasonal snowmelt, influencing flow patterns and pollutant transport.
