ETE Bonito MS - Wastewater Treatment Plant in Bonito, Mato Grosso do Sul, Brazil

ETE Bonito MS is a municipal wastewater treatment plant located in Bonito, Mato Grosso do Sul, Brazil, serving a population of about 13,274. The plant is situated along the Rodovia do Turismo near the Rio Formoso, a key waterway in the region known for its crystal-clear springs and ecotourism. As a medium-sized agglomeration, the plant plays a vital role in preserving the area's natural beauty. Brazil's wastewater treatment regulations are governed by federal standards under CONAMA resolutions and state-level environmental agencies. For plants serving populations between 10,000 and 100,000, secondary treatment is typically required to protect receiving water bodies. Its location in a sensitive karst environment suggests advanced treatment may be necessary to prevent groundwater contamination. The treated effluent is discharged into the Rio Formoso, which flows into the Miranda River and eventually reaches the Paraguay River basin, part of the larger Paraná-Paraguay system. This watershed supports diverse aquatic life and is critical for the Pantanal wetlands downstream. The plant's operation is essential for maintaining water quality in this ecologically sensitive region.

The plant discharges into the Rio Formoso, a tributary of the Miranda River, which flows into the Paraguay River and ultimately the Paraná-Paraguay basin. This watershed feeds the Pantanal, one of the world's largest tropical wetlands and a biodiversity hotspot. The region's karst geology makes groundwater particularly vulnerable to contamination, so effective treatment is crucial to protect aquatic ecosystems and the area's renowned clear-water springs.
