ETE Morada do Faval - Secondary Wastewater Treatment Plant in Cuiabá, Mato Grosso

ETE Morada do Faval is a wastewater treatment plant located in Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 372 residents in the São Francisco neighborhood, operating as part of the municipal sanitation infrastructure for the Cuiabá metropolitan area. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for urban wastewater. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant handles a discharge volume of 259.20 m³/day. The treated effluent is released into the Cuiabá River basin, which flows through the Pantanal region, one of the world's largest tropical wetlands. The Cuiabá River eventually joins the Paraguay River, contributing to the La Plata Basin. This downstream ecosystem supports diverse aquatic life and is ecologically sensitive, making proper wastewater treatment essential for water quality and biodiversity conservation.

The plant discharges into the Cuiabá River basin, which flows through the Pantanal, a vast floodplain ecosystem. The Cuiabá River is a tributary of the Paraguay River, ultimately draining into the La Plata Basin. The Pantanal is ecologically sensitive, supporting diverse aquatic species and migratory birds. Proper treatment helps protect this unique wetland environment from nutrient pollution and pathogens.
