ETE Jardim Antarctica - Secondary Wastewater Treatment Plant in Cuiabá, Brazil

ETE Jardim Antarctica is a wastewater treatment plant located in the Japuira neighborhood of Cuiabá, Mato Grosso, Brazil. It serves a small population of 283 residents within the Cuiabá metropolitan region, operating as part of the city's municipal sanitation infrastructure. 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 discharges approximately 196.80 cubic meters of treated effluent. The treated effluent is released into local water bodies within the Cuiabá River basin, which flows into the Paraguay River and ultimately into the Paraná River system. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The plant's operation helps protect downstream water quality in this ecologically sensitive region.

The plant discharges into the Cuiabá River basin, part of the larger Paraguay River watershed. This river system drains into the Pantanal, one of the world's largest tropical wetlands, which supports exceptional biodiversity and acts as a critical migratory corridor for aquatic species. The secondary treatment provided helps reduce organic pollution loads to this sensitive downstream ecosystem.
