ETE JUMIRIM Wastewater Treatment Plant, Jumirim, São Paulo, Brazil

ETE JUMIRIM is a municipal wastewater treatment plant located in Jumirim, a small town in the state of São Paulo, Brazil. The plant serves a population of approximately 1,502 residents, reflecting its role in a small agglomeration. It is situated along Rodovia Marechal Rondon in the central area of Jumirim, within the Sorocaba metropolitan region. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and state-level environmental licensing), secondary treatment is typically required for municipalities of this size. The plant's daily discharge volume is 177.70 cubic meters, indicating a modest operational scale consistent with the small population served. The treated effluent is discharged into local watercourses that drain into the Tietê River basin, a major watershed in São Paulo state. The Tietê River flows westward through the state and eventually joins the Paraná River system, which empties into the Río de la Plata estuary. The plant's operations help protect downstream water quality in this ecologically and economically important basin.

The plant discharges into small streams that feed the Tietê River basin, a critical water resource for São Paulo state. The Tietê River flows through densely populated and industrial areas before joining the Paraná River, which ultimately reaches the Río de la Plata estuary. The watershed supports diverse aquatic life and provides water for agriculture, industry, and drinking water. Secondary treatment reduces organic pollution, helping to maintain oxygen levels and ecosystem health in the receiving waters.
