DP01803901_CASTELLO_D_AGOGNA Wastewater Treatment Plant, Castello d'Agogna, Lombardy

DP01803901_CASTELLO_D_AGOGNA is an advanced wastewater treatment plant located in Castello d'Agogna, a municipality in the province of Pavia, Lombardy, Italy. The plant serves a population of approximately 2,142 and has a designed capacity of 2,500 cubic meters per day, with an average discharge volume of 424.04 cubic meters per 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 national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters and population size. The treated effluent is discharged into local watercourses that eventually drain into the Po River, Italy's longest river, which flows into the Adriatic Sea. The Po basin supports extensive agricultural activity and diverse aquatic ecosystems, making advanced treatment important for protecting water quality and ecological health.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River and its tributaries support a rich variety of aquatic life and are vital for irrigation in the Po Valley. Advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Adriatic, a semi-enclosed sea sensitive to algal blooms.
