Overview
ETE Sao Gabriel serves approximately 9,400 residents in Sao Gabriel do Oeste, Mato Grosso do Sul, Brazil. The plant is located inland, over 50 km from the coast, and discharges into local water bodies.
ETE Sao Gabriel is a municipal wastewater treatment plant serving the city of Sao Gabriel do Oeste in the state of Mato Grosso do Sul, Brazil. The plant supports a population of around 9,400 people, classifying it as a small to medium agglomeration under Brazilian sanitation standards. As a facility in Brazil, the plant operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies. Brazilian regulations require secondary treatment for urban wastewater, and plants of this scale typically employ biological processes such as activated sludge or stabilization ponds to meet effluent quality standards. The treated effluent is discharged into local watercourses that drain into the Parana River basin, one of South America's major river systems. The downstream environment includes the Parana River and eventually the Rio de la Plata estuary, supporting diverse aquatic ecosystems and providing water for agriculture and communities.
Environmental context
The plant's discharge flows into tributaries of the Parana River basin, which ultimately reaches the Rio de la Plata estuary. This watershed supports important aquatic biodiversity, including migratory fish species, and provides water for irrigation and human consumption. The region's tropical climate and agricultural activities make proper wastewater treatment essential for maintaining water quality in downstream ecosystems.
