ETE SAVIO BRANDAO Wastewater Treatment Plant, Cuiabá, Mato Grosso, Brazil

ETE SAVIO BRANDAO is a wastewater treatment plant located in the Jardim das Oliveiras neighborhood of Cuiabá, in the state of Mato Grosso, Brazil. The plant serves a small population of 124 residents and operates with secondary treatment, which is a standard biological process that removes organic matter and suspended solids. As part of Brazil's wastewater infrastructure, the plant helps manage domestic sewage in the Cuiabá metropolitan region. The plant provides secondary treatment, a level that meets basic regulatory requirements for organic pollutant removal. In Brazil, wastewater treatment is governed by CONAMA resolutions and state-level environmental agencies, which set discharge standards for parameters like BOD and TSS. For small agglomerations, secondary treatment is typically sufficient to protect receiving water bodies, though more advanced treatment may be required in sensitive areas. The treated effluent from ETE SAVIO BRANDAO is discharged into local waterways that flow into the Cuiabá River, a major tributary of the Paraguay River basin. This basin supports the Pantanal, one of the world's largest tropical wetlands and a critical ecosystem for biodiversity. The plant's operation helps reduce pollution loads entering this ecologically significant region, supporting aquatic life and downstream water quality.

The plant discharges into the Cuiabá River watershed, which drains into the Paraguay River and ultimately the Pantanal wetland. The Pantanal is a vast floodplain ecosystem that supports diverse aquatic and terrestrial species, including migratory birds, fish, and the jaguar. Secondary treatment at this plant helps control nutrient and organic pollution, reducing the risk of eutrophication and maintaining the ecological health of downstream water bodies.
