Overview
ETE Pascoal Moreira Cabral is a secondary treatment plant serving 124 people in Cuiabá, Mato Grosso, Brazil. It discharges 86.40 m³/day of treated wastewater into the local watershed.
ETE Pascoal Moreira Cabral is a municipal wastewater treatment plant located in the Lagoa Azul neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 124 residents and operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Secondary treatment is the minimum requirement under Brazilian CONAMA Resolution 430/2011 for most inland discharges. The plant's discharge volume is 86.40 m³/day, indicating a small-scale facility. The treated effluent is discharged into the Cuiabá River basin, which flows through the Pantanal, one of the world's largest tropical wetlands. The Pantanal is an ecologically sensitive region that supports diverse aquatic life and migratory bird populations. Proper treatment at this plant helps protect downstream water quality in this globally important ecosystem.
Environmental context
The plant discharges into the Cuiabá River, a tributary of the Paraguay River, which ultimately drains into the Pantanal wetlands and the Paraná River basin. The Pantanal is a vast floodplain ecosystem that supports high biodiversity, including jaguars, capybaras, and hundreds of fish species. Effective wastewater treatment is critical to prevent nutrient pollution and maintain the ecological health of this sensitive downstream environment.
