DP01807501_GRAVELLONA_LOMELLINA Wastewater Treatment Plant, Gravellona Lomellina, Lombardy

DP01807501_GRAVELLONA_LOMELLINA is an advanced wastewater treatment plant located in Gravellona Lomellina, a town in the province of Pavia, Lombardy, Italy. The plant serves a population of approximately 2,523 residents, classifying it as a small agglomeration under Italian and EU regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,000 m³/day and a current discharge volume of 499.46 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 water bodies that ultimately drain into the Po River basin, one of Italy's most significant watersheds. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities along its course.

The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. The Po River delta is an ecologically sensitive area that supports diverse aquatic life, including fish species and migratory birds. Advanced treatment at this plant helps reduce nutrient loading and protects downstream water quality in the Po River and the Adriatic coastal environment.
