DP01810901_PARONA Wastewater Treatment Plant, Parona, Lombardy

DP01810901_PARONA is an advanced wastewater treatment plant located in Parona, a municipality in the province of Pavia, Lombardy, Italy. The plant serves a population of 2,306 and is part of the regional wastewater infrastructure managed under Italian and European regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 2,250 m³/day, and it currently discharges 456.51 m³/day of treated wastewater. As an advanced facility, it meets stringent effluent quality standards required by the EU Urban Waste Water Treatment Directive for sensitive areas. The treated effluent is discharged into the local hydrographic network, which ultimately drains into the Po River basin. The Po River is Italy's longest river and flows into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po River supports a rich ecosystem, including migratory fish species and wetland habitats. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the Adriatic coastal zone.
