Overview
ETE Jardim das Aroeiras is a secondary treatment plant in Cuiabá, Mato Grosso, Brazil, serving 620 people. It discharges 432 m³/day of treated wastewater into the local watershed.
ETE Jardim das Aroeiras is a wastewater treatment plant located in the Murano Residence neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 620 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 level required under Brazilian regulations (CONAMA resolutions) for municipal wastewater. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant operates with a discharge volume of 432 cubic meters per day, indicating consistent operation. Treated effluent from the plant likely discharges into local watercourses that feed into the Cuiabá River, a major tributary of the Paraguay River basin. This basin is part of the Pantanal, one of the world's largest tropical wetlands and a critical ecosystem for biodiversity. The plant's treatment helps protect downstream water quality in this ecologically sensitive region.
Environmental context
The plant's treated effluent enters the Cuiabá River basin, which flows into the Paraguay River and ultimately feeds the Pantanal wetlands. The Pantanal is a vast floodplain ecosystem that supports diverse aquatic life, including fish, caimans, and migratory birds. Effective secondary treatment is crucial to prevent nutrient loading and maintain water quality in this sensitive downstream environment.
