DP01906401_OSTIANO Wastewater Treatment Plant, Ostiano, Lombardy, Italy

DP01906401_OSTIANO is an advanced wastewater treatment plant located in Ostiano, a town in the province of Cremona, Lombardy, Italy. The facility serves a population of approximately 3,270 residents, reflecting its role in managing municipal wastewater for a small community in the Po Valley region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,500 m³/day and a reported discharge volume of 647.34 m³/day, the plant operates well within its capacity. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the sensitivity of receiving waters. 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. The Po Valley is a densely populated and agriculturally intensive region, making advanced treatment important for protecting downstream water quality and aquatic ecosystems.

The plant discharges into the Oglio River, a tributary of the Po River, which flows eastward through Lombardy and into the Adriatic Sea. The Po River basin supports diverse aquatic life and is an important agricultural and industrial corridor. Advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Adriatic Sea.
