ETE Corrego Baiano Wastewater Treatment Plant, Assis Chateaubriand, Parana

ETE Corrego Baiano is a wastewater treatment plant located in Assis Chateaubriand, in the state of Parana, Brazil. The plant serves a population of approximately 10,715 people, making it a medium-sized facility for the region. It operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids through biological processes. The plant's treatment level aligns with typical requirements for municipalities of this scale in Brazil. The facility is part of the country's broader sanitation infrastructure, which aims to improve water quality and public health. The treated effluent from ETE Corrego Baiano is discharged into local water bodies that eventually drain into the Parana River basin. This basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and human consumption. The plant's operations help reduce pollution loads in the watershed, contributing to the preservation of downstream ecosystems.

The plant discharges into streams that flow into the Parana River basin, one of South America's major river systems. The Parana River ultimately reaches the Rio de la Plata estuary, supporting diverse aquatic habitats and migratory fish species. The region's subtropical climate and agricultural land use make effective wastewater treatment crucial for preventing nutrient enrichment and maintaining water quality in downstream water bodies.
