ETE Manduri Wastewater Treatment Plant, Manduri, São Paulo, Brazil

ETE Manduri is a municipal wastewater treatment plant located in Manduri, within the state of São Paulo, Brazil. The facility serves a population of approximately 7,467 people, classifying it as a small agglomeration under typical Brazilian sanitation frameworks. The plant is situated in the southeastern region of Brazil, an area characterized by a subtropical climate and significant agricultural activity. As a small-scale treatment facility, ETE Manduri is expected to comply with Brazilian national regulations for wastewater treatment, which generally require secondary treatment for urban areas. However, facilities of this size in São Paulo state often employ conventional activated sludge or lagoon systems to meet effluent standards. The treated effluent from ETE Manduri is discharged into local water bodies that drain into the Paranapanema River basin, a major tributary of the Paraná River system. This river network ultimately flows into the Río de la Plata estuary, supporting diverse aquatic ecosystems and providing water for downstream communities. The plant plays a key role in protecting local water quality and public health.

The plant discharges into the Paranapanema River basin, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The subtropical climate and surrounding agricultural land use mean that nutrient management is a key ecological consideration to prevent eutrophication in downstream water bodies.
