ETE Anhumas SP - Secondary Wastewater Treatment in Anhumas, São Paulo

ETE Anhumas SP is a municipal wastewater treatment plant located in the Conjunto Habitacional Jorge Sereguetti area of Anhumas, within the state of São Paulo, Brazil. The plant serves a population of around 3,140 residents, classifying it as a small-scale facility in the region. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for inland communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring effluent meets basic quality standards before discharge. The treated effluent from ETE Anhumas SP is discharged into local water bodies that ultimately 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, industry, and drinking water downstream. The plant's operation helps protect these resources from untreated sewage pollution.

The plant discharges into local streams that flow into the Paraná River basin, which drains into the Río de la Plata estuary. This watershed supports diverse aquatic life, including fish species important for regional fisheries. The secondary treatment reduces organic load and pathogens, mitigating eutrophication risks in downstream water bodies.
