DP01800501_ARENA_PO_VIA_MANDELLI - Advanced Wastewater Treatment in Arena Po, Lombardy

DP01800501_ARENA_PO_VIA_MANDELLI is a wastewater treatment plant located in Arena Po, a municipality in the province of Pavia, Lombardy, Italy. The plant serves a small population of 160 and is situated in the Po River valley, a densely populated and agriculturally intensive region. It is classified as an advanced treatment facility, reflecting a high level of nutrient removal and effluent quality. The plant has a designed capacity of 160 m³/day and currently discharges 31.67 m³/day of treated wastewater. As an advanced treatment plant, it likely incorporates tertiary processes such as filtration or nutrient removal, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's small scale aligns with its rural setting, where decentralized treatment is common. The treated effluent is discharged into local watercourses that ultimately flow into the Po River, Italy's longest river, which drains into the Adriatic Sea. The Po basin supports extensive agriculture and is ecologically significant, hosting diverse aquatic life. The plant's advanced treatment helps protect downstream water quality and the sensitive delta ecosystem.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea via the Po Delta. The Po River is a vital water resource for irrigation, industry, and drinking water, and its delta is an ecologically sensitive area supporting diverse bird species and aquatic habitats. Advanced treatment at this plant reduces nutrient loads, helping to mitigate eutrophication risks in the Adriatic.
