Overview
ETE PADILHA SUL is a wastewater treatment plant in São José dos Pinhais, Paraná, Brazil, serving approximately 160,000 people. It operates under Brazil's national water quality regulations.
ETE PADILHA SUL is a wastewater treatment plant located in the Colônia Rio Grande area of São José dos Pinhais, within the Curitiba metropolitan region in Paraná, Brazil. The plant serves a population of around 160,000, placing it in the large agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997). For plants of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. It is expected to comply with federal and state environmental regulations. The plant discharges into local water bodies that drain into the Iguaçu River basin, which flows through Paraná and eventually into the Paraná River. This river system supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment at ETE PADILHA SUL helps protect downstream ecosystems and water quality.
Environmental context
The plant's treated effluent likely enters the Iguaçu River basin, which flows through the Atlantic Forest biome and eventually joins the Paraná River. This watershed supports diverse aquatic species and provides water for communities and agriculture. The region's subtropical climate with high rainfall means that effective wastewater treatment is crucial to prevent nutrient loading and protect downstream water quality.
