ETE Jardim Vitoria B Wastewater Treatment Plant, Cuiabá, Mato Grosso

ETE Jardim Vitoria B is a wastewater treatment plant located in the Jardim Vitoria neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 248 residents, reflecting its role in a localized residential area within the broader Cuiabá metropolitan region. The plant provides secondary treatment, which is the standard biological treatment process required under Brazilian regulations (CONAMA resolutions) for municipal wastewater. This level of treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant discharges a daily volume of 172.80 cubic meters of treated effluent. The treated effluent from ETE Jardim Vitoria B flows into the Cuiabá River basin, which is part of the larger Paraguay River watershed. The Cuiabá River is a major tributary of the Paraguay River, ultimately draining into the Pantanal, one of the world's largest tropical wetlands. The Pantanal is an ecologically sensitive region that supports diverse aquatic life and migratory bird populations, making proper wastewater treatment crucial for preserving water quality and biodiversity.

The plant discharges into the Cuiabá River basin, which flows into the Paraguay River and eventually the Pantanal wetland. The Pantanal is a vast floodplain ecosystem that supports high biodiversity, including fish, caimans, and migratory birds. Secondary treatment helps reduce nutrient and organic loads, protecting downstream aquatic habitats from eutrophication and oxygen depletion.
