Overview
ETE Samambaia Campinas serves approximately 33,214 people in Campinas, São Paulo, Brazil. The plant operates under Brazil's national wastewater regulations for medium-sized agglomerations.
ETE Samambaia Campinas is a wastewater treatment plant located in Campinas, within the state of São Paulo, Brazil. It serves a population of around 33,214 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. The plant is situated in the Região Metropolitana de Campinas, a densely populated and industrialized region in southeastern Brazil. Brazil's wastewater treatment standards are governed by federal regulations, including CONAMA resolutions and state-level environmental agencies. For plants of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. It is expected to comply with applicable discharge permits issued by the São Paulo environmental agency (CETESB). The treated effluent from ETE Samambaia Campinas is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. The region's water resources support diverse aquatic life and are used for drinking water supply, agriculture, and industry downstream. Proper treatment is essential to protect water quality in the receiving streams and the broader Paraná watershed.
Environmental context
The plant discharges into tributaries of the Piracicaba River, which flows into the Tietê River and eventually reaches the Paraná River basin. The Paraná River drains into the Río de la Plata estuary, supporting ecologically sensitive wetlands and diverse aquatic habitats. The region's water bodies are important for local biodiversity and human water use, requiring effective treatment to prevent nutrient pollution and maintain ecosystem health.
