DP01518901_ROZZANO Wastewater Treatment Plant, Rozzano, Lombardy, Italy

DP01518901_ROZZANO is a wastewater treatment plant located in Rozzano, a municipality in the Metropolitan City of Milan, Lombardy, Italy. The plant serves a population of approximately 48,900, placing it in the medium agglomeration category under Italian and EU regulations. It is situated in the densely populated Po Valley, an area with significant industrial and agricultural activity. As a plant serving a population equivalent of nearly 50,000, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The plant discharges into the local water network, which ultimately drains into the Po River basin. The Po River is Italy's longest river and flows into the Adriatic Sea, supporting diverse aquatic ecosystems and providing water for irrigation and industry. Proper treatment at this plant helps protect downstream water quality in the Po Valley and the Adriatic coastal environment.

The plant is located in the Po Valley, a major agricultural and industrial region in northern Italy. Treated effluent from the plant likely enters local canals or tributaries that flow into the Po River, which then discharges into the Adriatic Sea. The Po River basin supports a variety of aquatic life and is an important migratory corridor for fish. The Adriatic Sea near the Po delta is ecologically sensitive due to nutrient inputs that can cause eutrophication, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
