ETE TORRES Wastewater Treatment Plant, Cuiabá, Mato Grosso, Brazil

ETE TORRES is a wastewater treatment plant located in the Condomínio Flor do Cerrado area of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 620 residents, reflecting its role in a residential or peri-urban community within the Cuiabá metropolitan region. The plant provides secondary treatment, a standard level for smaller agglomerations under Brazilian regulations (CONAMA resolutions and state environmental licensing). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 432.00 m³/day indicates a modest flow consistent with its service population. Treated effluent from ETE TORRES likely enters local watercourses that drain into the Cuiabá River, a major tributary of the Paraguay River basin. This basin feeds the Pantanal, one of the world's largest tropical wetlands and a critical ecosystem for biodiversity. Proper treatment helps protect downstream water quality in this ecologically sensitive region.

The plant's discharge ultimately reaches the Cuiabá River, which flows into the Paraguay River and feeds the Pantanal wetland system. The Pantanal is a vast floodplain supporting diverse aquatic life, migratory birds, and endangered species. Maintaining secondary treatment standards helps reduce nutrient and organic loads that could otherwise contribute to eutrophication and habitat degradation in this globally important ecosystem.
