Overview
DP01518401_ROBECCO_SUL_NAVIGLIO is a wastewater treatment plant serving Casterno, Robecco sul Naviglio, in Lombardy, Italy. It handles a population equivalent of approximately 247,000, classifying it as a large agglomeration under EU regulations.
DP01518401_ROBECCO_SUL_NAVIGLIO is a wastewater treatment plant located in Casterno, a locality within the municipality of Robecco sul Naviglio, in the Lombardy region of northern Italy. The plant serves a population equivalent of approximately 247,000, placing it in the category of large agglomerations under the EU Urban Waste Water Treatment Directive (UWWTD). Its location in the Po Valley, a densely populated and agriculturally intensive area, underscores its importance for regional water quality management. As a large agglomeration, the plant is expected to provide at least secondary treatment under the EU UWWTD, with potential requirements for more advanced treatment if discharging into sensitive areas. The regulatory framework in Italy, transposing the directive, mandates compliance with discharge standards to protect receiving water bodies. Its scale implies significant infrastructure to manage the wastewater load. The plant's treated effluent likely discharges into the Naviglio Grande canal system, which connects to the Ticino River, a major tributary of the Po River. The Po River flows into the Adriatic Sea, making the plant part of a basin that supports diverse aquatic life and agricultural irrigation. Effective treatment is critical to prevent nutrient pollution and protect downstream ecosystems, including the Po Delta and coastal waters.
Environmental context
The plant is situated in the Po River basin, Italy's largest drainage basin, which flows eastward into the Adriatic Sea. The immediate receiving water body is likely the Naviglio Grande, a historic canal that feeds into the Ticino River, a key tributary of the Po. The Po Delta is an ecologically sensitive area supporting diverse bird species and fish populations, and nutrient loading from upstream sources can contribute to eutrophication in the Adriatic. The plant's treatment performance is therefore important for maintaining water quality in this agriculturally and ecologically significant watershed.
Frequently asked questions
The plant is located in Casterno, a locality within the municipality of Robecco sul Naviglio, in the province of Milan, Lombardy, Italy.
The plant serves a population equivalent of approximately 247,000, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent likely discharges into the Naviglio Grande canal system, which connects to the Ticino River, a tributary of the Po River, ultimately reaching the Adriatic Sea.
As an Italian plant serving over 150,000 people, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires at least secondary treatment and potentially tertiary treatment if discharging into sensitive areas.
For large agglomerations in Italy, secondary treatment is mandatory, and advanced treatment (nutrient removal) is often required for discharges into sensitive water bodies like the Po River basin to prevent eutrophication.
