DP09701204_CALCO_TOFFO is a municipal wastewater treatment plant located in Arlate, a frazione of Calco, in the province of Lecco, Lombardia, Italy. The plant serves a population equivalent of 27,227, classifying it as a medium agglomeration under EU regulations. It is situated in the Adda River basin, a tributary of the Po River, which ultimately drains into the Adriatic Sea. As a plant operating in Italy, it falls 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. Compliance with the directive ensures a minimum level of treatment to protect water quality. The treated effluent from the plant is discharged into the local water network, contributing to the Adda River system. The Adda flows into the Po River, which is the longest river in Italy and supports extensive agricultural and ecological systems before reaching the Adriatic Sea. The plant plays a key role in maintaining the health of these downstream waters by reducing pollutant loads.
Environmental context
The plant discharges into the Adda River basin, which flows into the Po River and then the Adriatic Sea. The Po River delta is an ecologically sensitive area supporting diverse aquatic life and migratory bird species. The plant's operations help protect this downstream environment by treating wastewater before release, reducing nutrient and pathogen loads that could otherwise impact water quality and biodiversity.

As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 PE and more advanced treatment in sensitive areas.
Under the EU UWWTD, plants serving 10,000 to 100,000 PE typically require secondary treatment (biological treatment with secondary settling). In sensitive areas, tertiary treatment for nutrient removal may be mandated.
