ETE Lupercio Wastewater Treatment Plant, Lupércio, São Paulo, Brazil

ETE Lupercio is a wastewater treatment plant located in Lupércio, a municipality in the state of São Paulo, Brazil. The plant serves a population of about 3,760 people, placing it in the small agglomeration category under Brazilian wastewater management frameworks. It operates in the interior of São Paulo, an area characterized by agricultural and small urban settlements. The plant provides secondary treatment, which is the standard level required for most Brazilian municipalities under national regulations. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The reported discharge volume of 277.20 units indicates the plant's operational throughput. Brazilian wastewater facilities are regulated by state environmental agencies, with São Paulo's CETESB overseeing compliance. The treated effluent from ETE Lupercio is discharged into local water bodies that eventually drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and human consumption. Proper treatment at plants like ETE Lupercio helps protect downstream water quality and ecological health.

The plant discharges into local streams that flow into the Paraná River basin, a vast watershed covering parts of Brazil, Paraguay, and Argentina. The Paraná River ultimately empties into the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and riparian habitats, making effective wastewater treatment crucial for maintaining water quality and ecological balance.
