Overview
ETE Vila São João is a secondary treatment plant serving 440 people in Várzea Grande, Mato Grosso, Brazil. It discharges 40.16 m³/day of treated wastewater into the local watershed.
ETE Vila São João is a municipal wastewater treatment plant located in the Jardim Paula II neighborhood of Várzea Grande, Mato Grosso, Brazil. The plant serves a small population of 440 residents and operates with secondary treatment, which is appropriate for its scale under Brazilian regulations. As a secondary treatment facility, the plant removes organic matter and suspended solids through biological processes, meeting the standards set by Brazil's National Environment Council (CONAMA). For small agglomerations like this, secondary treatment is the typical requirement to protect water quality in the receiving environment. The treated effluent is discharged into the Cuiabá River basin, which flows through the Pantanal region, one of the world's largest tropical wetlands. The plant's operation helps reduce nutrient and organic pollution entering this ecologically sensitive area, supporting aquatic life and downstream water quality.
Environmental context
The plant discharges into the Cuiabá River watershed, which drains into the Pantanal, a vast floodplain ecosystem that supports diverse aquatic life and migratory species. The Pantanal is a critical habitat for fish, birds, and other wildlife, and its water quality depends on effective wastewater treatment upstream. By providing secondary treatment, the plant helps mitigate nutrient loading and organic pollution that could otherwise harm this sensitive environment.
