San Salvatore Monferrato Wastewater Treatment Plant | Piemonte, Italy

The San Salvatore Monferrato wastewater treatment plant is located in the town of San Salvatore Monferrato, in the province of Alessandria, Piemonte region, Italy. The facility serves a population of approximately 2,300 residents and is part of the municipal wastewater infrastructure for this small agglomeration. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 3,000 cubic meters per day and currently treats an average daily volume of about 515 cubic meters, indicating ample capacity for current loads. The treated effluent is discharged into local watercourses that drain into the Po River basin, ultimately reaching the Adriatic Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the Po River system and downstream ecosystems.

The plant discharges into the Po River basin, which flows eastward across northern Italy to the Adriatic Sea. The Po River is the longest river in Italy and supports diverse aquatic life, including fish species such as sturgeon and eel. The watershed is ecologically sensitive due to agricultural runoff and industrial pressures, making the plant's secondary treatment important for reducing nutrient and organic pollution in the river and its delta.
