The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is typically required for municipal wastewater to protect water quality. The plant's discharge volume is 202.83 m³/day, indicating its scale as a small facility. The treated effluent is discharged into local water bodies that drain into the Piracicaba River basin, a key watershed in São Paulo state. This basin supports diverse aquatic life and is used for water supply, agriculture, and recreation downstream. Proper treatment at plants like ETE FF RAVAGNANI helps reduce nutrient and pathogen loads, safeguarding the ecological health of the Piracicaba River and its eventual flow into the Paraná River system.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River and ultimately the Paraná River, a major South American waterway. The basin supports diverse aquatic ecosystems and is important for regional water supply. Effective secondary treatment reduces organic pollution and nutrient loading, helping to maintain water quality in this ecologically sensitive watershed.
