DP01811301_PIEVE_DEL_CAIRO_CAPOLUOGO Wastewater Treatment Plant, Pieve del Cairo, Lombardy

DP01811301_PIEVE_DEL_CAIRO_CAPOLUOGO is an advanced wastewater treatment plant located in Pieve del Cairo, a municipality in the province of Pavia, Lombardy, Italy. The plant serves a population of approximately 2,009 residents and has a design capacity of 3,000 cubic meters per day, with a current discharge volume of about 398 m³/day. It is situated inland, away from coastal areas, and operates under Italian and European wastewater regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. As a facility serving a small agglomeration (under 10,000 population equivalent), it is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment based on the sensitivity of receiving waters. The plant's advanced treatment level suggests it discharges into a sensitive area or is designed to meet stringent standards. The treated effluent is discharged into local watercourses that ultimately drain into the Po River basin, one of Italy's most significant hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Po Valley.

The plant discharges into the Po River basin, which drains the Po Valley and flows into the Adriatic Sea. This region is agriculturally intensive and ecologically sensitive, with the Po Delta supporting diverse habitats and migratory bird populations. Advanced treatment at this plant reduces nutrient loading, helping to mitigate eutrophication risks in downstream waters and the Adriatic.
