ETE Sao Lourenco Londrina is a wastewater treatment facility located in the Parque das Industrias district of Londrina, in the state of Parana, Brazil. The plant serves a population of about 16,755 residents, classifying it as a small to medium-sized agglomeration within the region's sanitation infrastructure. Brazil's wastewater treatment sector is governed by federal laws such as the National Water Resources Policy (Law 9.433/1997) and CONAMA resolutions, which set discharge standards for pollutants. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Parana River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at this plant helps protect water quality in the region's streams and rivers.
Environmental context
The plant discharges into the Parana River basin, which flows through southern Brazil and into the Rio de la Plata estuary. This watershed supports a variety of aquatic life, including fish species important for local fisheries. The region's subtropical climate and agricultural land use make nutrient management a key concern for preventing eutrophication in downstream water bodies.
