ETE ENTRE RIOS Wastewater Treatment Plant, Cuiabá, Mato Grosso, Brazil

ETE ENTRE RIOS is a wastewater treatment plant located in the Jardim Universitário neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 124 residents, reflecting its role as a local facility for a condominium or small community. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland wastewater discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from ETE ENTRE RIOS is discharged into the local watershed, which is part of the Cuiabá River basin. The Cuiabá River flows through the Pantanal, one of the world's largest tropical wetlands and a critically important ecosystem for biodiversity. The plant's secondary treatment helps protect downstream water quality in this sensitive environment.

The plant discharges into the Cuiabá River basin, which drains into the Pantanal region, a vast floodplain and ecologically sensitive area. The Pantanal supports diverse aquatic life, including fish, caimans, and migratory birds. Secondary treatment reduces organic pollutants, helping to maintain water quality in this downstream ecosystem.
