DP01504601_CANEGRATE_OLONA_NORD Wastewater Treatment Plant, Parabiago, Italy

DP01504601_CANEGRATE_OLONA_NORD is a wastewater treatment plant located in Parabiago, within the Lombardia region of northern Italy. It serves a population of approximately 134,535, classifying it as a large agglomeration under EU regulations. The plant is situated in the densely populated Po Valley, an area with significant industrial and agricultural activity. As a large agglomeration, the plant is expected to provide at least secondary treatment under the EU Urban Waste Water Treatment Directive (91/271/EEC), with tertiary treatment required if discharging into sensitive areas. The directive mandates compliance with effluent standards to protect water quality. Regulatory frameworks ensure appropriate treatment levels for the population served. The treated effluent likely discharges into the Olona River, a tributary of the Po River, which flows into the Adriatic Sea. The Po Valley is a critical agricultural region, and the plant plays a key role in preventing nutrient pollution and safeguarding downstream ecosystems, including the Po Delta and the Adriatic coastal zone.

The plant discharges into the Olona River, which flows into the Lambro River and then the Po River, ultimately reaching the Adriatic Sea. The Po Valley is a major agricultural area, and nutrient loading from wastewater can contribute to eutrophication in the Adriatic. The plant's treatment helps protect sensitive downstream habitats, including the Po Delta, which supports diverse aquatic life and migratory bird species.
