DP01206401_DAVERIO Wastewater Treatment Plant, Daverio, Lombardy, Italy

DP01206401_DAVERIO is a wastewater treatment facility located in Daverio, a town in the province of Varese, Lombardy, Italy. The plant serves a population of about 4,084 and has a designed capacity of 5,000 m³/day, with an average discharge volume of 808.49 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive areas. For a plant of this scale (serving fewer than 10,000 people), secondary treatment is typically mandated, but the advanced level indicates a higher standard of effluent quality. The treated effluent is discharged into local watercourses that eventually drain into the Po River basin and the Adriatic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems, and ensuring compliance with European environmental standards.

The plant discharges into the local drainage network within the Po River basin, which flows eastward into the Adriatic Sea. The region is characterized by intensive agriculture and urban development, making nutrient removal critical to prevent eutrophication in downstream waters. The advanced treatment helps protect sensitive aquatic habitats and supports biodiversity in the Po delta and coastal Adriatic ecosystems.
