ETE FOSSA RESERVA DO PARQUE - Secondary Wastewater Treatment in Cuiabá, Mato Grosso

ETE FOSSA RESERVA DO PARQUE is a wastewater treatment plant located in the Despraiado neighborhood of Cuiabá, Mato Grosso, Brazil. The plant serves a small population of 94 residents, providing secondary treatment for domestic wastewater. It is part of the municipal sanitation infrastructure managed by the local water utility. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. As a small-scale facility, it likely uses a simplified treatment process such as an anaerobic or aerobic system, common for small communities. The plant's discharge volume is 65.76 m³ per day, indicating consistent operation. The treated effluent is discharged into local water bodies that drain into the Cuiabá River basin, part of the larger Paraguay River watershed. This region is ecologically significant, supporting the Pantanal wetlands, one of the world's largest freshwater ecosystems. Proper treatment helps protect downstream water quality and biodiversity.

The plant discharges into the Cuiabá River basin, which flows into the Paraguay River and ultimately the Pantanal, a vast tropical wetland. The Pantanal is a critical habitat for diverse aquatic species and migratory birds. Effective secondary treatment reduces organic load and pathogens, safeguarding this sensitive downstream ecosystem from eutrophication and contamination.
