DP09801301_CASTELNUOVO_BOCCA_D_ADDA Wastewater Treatment Plant, Castelnuovo Bocca d'Adda, Lombardy

DP09801301_CASTELNUOVO_BOCCA_D_ADDA is an advanced wastewater treatment plant located in Castelnuovo Bocca d'Adda, a municipality in the province of Lodi, Lombardy, Italy. The plant serves a population of approximately 2,170 residents, reflecting its role in managing wastewater for a small agglomeration in the Po River basin. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,500 m³/day and a discharge volume of 429.58 m³/day, the facility operates well within its capacity. As an Italian plant, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Po River, Italy's longest river, which flows into the Adriatic Sea. This makes the plant's advanced treatment crucial for protecting the Po River ecosystem and the downstream marine environment from nutrient pollution.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po River supports diverse aquatic life and is an important agricultural and ecological corridor. Advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Adriatic, a semi-enclosed sea sensitive to algal blooms.
