ETE Pavodani Wastewater Treatment Plant, Capivari, São Paulo

ETE Pavodani is a wastewater treatment plant located in Capivari, within the state of São Paulo, Brazil. It serves a small population of 657 residents, operating as a secondary treatment facility. The plant is part of the municipal infrastructure managed under Brazilian environmental regulations. The plant provides secondary treatment, which is appropriate for its small scale. In Brazil, wastewater treatment plants are regulated by federal and state environmental agencies, with standards set by CONAMA resolutions. For small agglomerations, secondary treatment is typically sufficient to meet discharge requirements and protect receiving water bodies. The treated wastewater from ETE Pavodani is discharged into local watercourses that drain into the Piracicaba River basin, part of the larger Paraná River system. This region supports diverse aquatic life and is important for water supply and agriculture. The plant's operation helps reduce nutrient and organic pollution in the downstream environment.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River and ultimately reaches the Paraná River and the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and is used for irrigation and drinking water. The secondary treatment reduces organic load and nutrients, helping to protect downstream water quality.
