DP01314301_MARIANO_COMENSE is a municipal wastewater treatment plant located in Mariano Comense, a town in the province of Como, Lombardy, Italy. The plant serves a population of approximately 58,987 people, placing it in the medium agglomeration category under European Union regulations. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. Compliance with the directive ensures appropriate treatment standards. The plant discharges treated wastewater 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 agriculture and industry. The plant plays a key role in protecting water quality in this densely populated and economically important region.
Environmental context
The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. The Po River supports a rich ecosystem, including fish species such as sturgeon and eel, and provides water for irrigation and industry. The Adriatic Sea is a semi-enclosed sea with sensitive marine habitats, including seagrass meadows and nursery areas for fish. Proper wastewater treatment is essential to prevent nutrient pollution and protect biodiversity in this ecologically significant region.
