DP01523101_VAREDO_SEVESO_NORD Wastewater Treatment Plant, Varedo, Lombardy

DP01523101_VAREDO_SEVESO_NORD is a municipal wastewater treatment plant located in Varedo, in the Lombardy region of Italy. The plant serves a population equivalent of 103,089, classifying it as a large agglomeration under EU regulations. It is situated in the densely populated Po Valley, an area with significant industrial and agricultural activity. As a large agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and more advanced treatment if the receiving waters are sensitive. The regulatory framework ensures compliance with discharge standards appropriate for its scale. The plant discharges treated wastewater into the local water network, which ultimately drains into the Po River basin and then into the Adriatic Sea. The Po Valley is a critical ecological and economic region, and the plant plays a key role in protecting water quality in this densely populated and agriculturally intensive area.

The plant's treated effluent enters the local hydrographic network, which flows into the Po River, Italy's longest river. The Po River basin supports diverse aquatic life and is an important agricultural and industrial corridor. Downstream, the Po Delta is an ecologically sensitive area that provides habitat for numerous bird species and supports wetland ecosystems. The plant's discharge must meet stringent standards to protect these downstream environments.
