It serves a population of 2,919 people, classifying it as a small agglomeration under Italian and EU regulations. The plant is situated along the Po River, reflecting its role in managing wastewater from this rural community. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. It has a designed capacity of 4,000 m³/day and currently discharges an average volume of 536.93 m³/day, indicating operational capacity well below its design limit.

The treated effluent is discharged into the Po River, Italy's longest river, which flows eastward into the Adriatic Sea. The Po basin supports extensive agriculture and diverse aquatic ecosystems. The plant's operation helps protect water quality in the Po River and downstream environments, including the Po Delta, a region of ecological importance for migratory birds and fish species.

The SARMATO plant discharges into the Po River, which flows through northern Italy and empties into the Adriatic Sea via the Po Delta. The Po basin is a major agricultural and industrial region, and the river supports diverse aquatic life, including fish species such as sturgeon and eel. The delta is an important wetland for migratory birds. Secondary treatment reduces organic pollutants, helping to maintain water quality in this ecologically sensitive river system.
