DP01213902_VIGGIU_BEVERA Wastewater Treatment Plant, Baraggia, Viggiù, Lombardy

DP01213902_VIGGIU_BEVERA is an advanced wastewater treatment plant located in Baraggia, a locality within the municipality of Viggiù, in the province of Varese, Lombardy, Italy. The plant serves a population of 2,189 and has a designed capacity of 3,000 m³/day, with an average discharge volume of 433.34 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant operates within Italy's national regulatory framework, which implements the directive through Decreto Legislativo 152/2006. The treated effluent is discharged into local watercourses that eventually drain into the Po River basin, which flows into the Adriatic Sea. The plant plays a crucial role in protecting the region's water quality, particularly given the proximity to the Po Valley, a densely populated and agriculturally intensive area.

The plant discharges into local streams that are part of the Olona River basin, a tributary of the Po River. The Po River flows eastward across northern Italy and empties into the Adriatic Sea. This watershed supports diverse aquatic life and is important for irrigation and drinking water supply. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Adriatic Sea.
