Overview
DP01521001_SETTALA is a wastewater treatment plant serving Caleppio, Settala, in Lombardy, Italy. It handles a population equivalent of approximately 46,805 and operates under the EU Urban Waste Water Treatment Directive.
DP01521001_SETTALA is a wastewater treatment plant located in Caleppio, a frazione of Settala in the Lombardy region of northern Italy. The plant serves a population equivalent of 46,805, placing it in the medium agglomeration category under EU classification. It is situated in the Po Valley, a densely populated and agriculturally intensive area. As a plant of this scale in Italy, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For discharges into sensitive areas, tertiary treatment may be mandated. Regulatory compliance ensures appropriate treatment standards. The treated effluent is discharged into the local water network, which ultimately drains into the Po River and then into the Adriatic Sea. The Po basin is a critical ecological and economic resource, supporting diverse aquatic life and providing water for agriculture and industry. The plant plays a key role in protecting water quality in this important watershed.
Environmental context
The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po River is Italy's longest river and supports a rich ecosystem, including fish species such as sturgeon and eel. The surrounding area is intensively farmed, making nutrient removal important to prevent eutrophication in the Adriatic. The plant's location inland, over 50 km from the coast, reduces direct marine impact but its discharge contributes to the overall health of the Po watershed.
