Overview
ETE VIVERDI 2 is a secondary treatment plant in Cuiabá, Mato Grosso, Brazil, serving 124 people. It discharges 86.40 m³/day of treated wastewater, contributing to local water quality management.
ETE VIVERDI 2 is a wastewater treatment plant located in the Viverde Condominium in the Despraiado area of Cuiabá, Mato Grosso, Brazil. It serves a small population of 124 residents, reflecting its role as a local facility for a residential community within the broader Cuiabá metropolitan region. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Secondary treatment aligns with Brazilian regulatory requirements for smaller agglomerations under CONAMA resolutions and state-level environmental permits. The treated effluent is discharged into the local watershed, which ultimately drains into the Cuiabá River, a major tributary of the Paraguay River basin. This basin supports the Pantanal, one of the world's largest tropical wetlands, making proper treatment essential for downstream ecological health.
Environmental context
The plant's discharge enters the Cuiabá River system, part of the Upper Paraguay River basin. This basin feeds the Pantanal, a vast floodplain ecosystem that supports diverse aquatic life, migratory birds, and endangered species. Effective secondary treatment helps reduce nutrient and organic loads, protecting water quality in this ecologically sensitive region.
