Overview
ETE São Luiz serves Cornélio Procópio, Paraná, Brazil, treating wastewater for approximately 18,125 residents. The plant operates under Brazil's national environmental regulations for municipal wastewater treatment.
ETE São Luiz is a municipal wastewater treatment plant located in Cornélio Procópio, a city in the state of Paraná, Brazil. The plant serves a population of about 18,125 people, placing it in the small-to-medium agglomeration category. It is situated in the southern region of Brazil, an area characterized by subtropical climate and agricultural activity. Brazil's wastewater treatment framework is governed by federal laws such as the National Environmental Policy (Law 6.938/1981) and CONAMA resolutions, which set discharge standards for organic matter and pathogens. The regulatory framework emphasizes protection of water resources and public health. The treated effluent from ETE São Luiz is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward, contributing to the La Plata Basin, which empties into the Atlantic Ocean. This downstream connection underscores the plant's role in protecting regional water quality and aquatic ecosystems.
Environmental context
The plant's discharge enters local streams that feed into the Paraná River basin, a vast watershed supporting diverse aquatic life and agricultural irrigation. The Paraná River flows through Brazil, Paraguay, and Argentina, eventually reaching the Río de la Plata estuary. Protecting this downstream environment requires effective treatment to reduce nutrient loads and pathogens, which can impact fisheries and drinking water sources in the region.
Frequently asked questions
ETE São Luiz is located in Cornélio Procópio, a city in the state of Paraná, Brazil. The plant serves the municipal wastewater needs of the local population.
The plant serves approximately 18,125 people, classifying it as a small-to-medium agglomeration under Brazilian wastewater management categories.
The treated effluent is discharged into local water bodies that are part of the Paraná River basin. The Paraná River ultimately flows into the Río de la Plata estuary and the Atlantic Ocean.
The plant operates under Brazil's federal environmental laws, including CONAMA resolutions that set effluent discharge standards. For plants of this scale, secondary treatment is typically required to meet organic matter and pathogen limits.
In Brazil, municipal plants serving around 18,000 people generally employ secondary treatment processes such as activated sludge or stabilization ponds to comply with CONAMA standards. These processes reduce biochemical oxygen demand (BOD) and pathogen levels before discharge.
