DP01406701_TORRE_S_MARIA Wastewater Treatment Plant, Torre di Santa Maria, Lombardy

DP01406701_TORRE_S_MARIA is a wastewater treatment plant located in Torre di Santa Maria, a municipality in the province of Sondrio, Lombardy, Italy. The plant serves a population equivalent of 17,284, placing it in the medium agglomeration category under EU classification. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The regulatory framework ensures compliance with national and EU standards for wastewater treatment. The plant discharges treated effluent into the local watershed, which ultimately drains into the Adda River, a major tributary of the Po River. The Po River flows into the Adriatic Sea, making this plant part of the broader Po basin ecosystem. The surrounding area is characterized by alpine terrain and supports diverse aquatic life, requiring careful management of nutrient loads to prevent eutrophication.

The plant's treated effluent enters the local watercourse, which flows into the Adda River and then the Po River, eventually reaching the Adriatic Sea. The Po basin is ecologically significant, supporting diverse aquatic species and serving as a migratory corridor for fish. The alpine watershed is sensitive to nutrient pollution, making effective treatment essential for downstream water quality.
