DP01201701_BREBBIA_VAREE Wastewater Treatment Plant, Bogno, Lombardy

DP01201701_BREBBIA_VAREE is an advanced wastewater treatment plant located in Bogno, a locality within the municipality of Besozzo in the province of Varese, Lombardy, Italy. The plant serves a population of approximately 3,242 people and has a designed capacity of 3,000 cubic meters per day, with an actual discharge volume of 641.80 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size to protect sensitive water bodies. The treated effluent is discharged into the local water system, ultimately flowing into the Bardello stream and then into Lake Varese, part of the Po River basin. This region is ecologically sensitive, supporting diverse aquatic life and serving as an important area for bird migration and local biodiversity.

The plant discharges into the Bardello stream, which flows into Lake Varese, a shallow lake in the Po River basin. Lake Varese is a key ecological site, supporting fish populations and migratory birds. The advanced treatment helps protect the lake from eutrophication, a concern due to nutrient inputs from surrounding agricultural and urban areas.
