ETE Sao Domingos Wastewater Treatment Plant, Cambé, Paraná, Brazil

ETE Sao Domingos is a wastewater treatment plant located in Cambé, within the state of Paraná, Brazil. The plant serves a population of around 20,735 residents, contributing to the municipal sanitation infrastructure of this urban area in the southern region of the country. Brazil's wastewater treatment facilities operate under national regulations established by the Ministry of Cities and state environmental agencies. For a plant of this scale, secondary treatment is typically required to meet effluent standards before discharge. The plant's capacity and treatment process details are managed by the local utility to comply with these standards. The treated effluent from ETE Sao Domingos is discharged into local water bodies that 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 communities downstream. Proper treatment helps protect water quality in the region.

The plant discharges into the Paraná River basin, which flows through southern Brazil and eventually into the Río de la Plata estuary. This watershed supports important aquatic habitats and is used for water supply and recreation. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain ecological balance in the basin.
