Overview
ETE Sao Carlos is a municipal wastewater treatment plant serving approximately 8,927 people in Cuiabá, Mato Grosso, Brazil. It operates under Brazil's national environmental regulations for water quality.
ETE Sao Carlos is a wastewater treatment plant located in the Sol Nascente neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a population of around 8,927 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment facilities are regulated under the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy. For plants of this scale, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. The plant's location in the Cuiabá metropolitan area means it contributes to regional sanitation goals. The treated effluent from ETE Sao Carlos likely discharges into a tributary of the Cuiabá River, which flows into the Paraguay River basin. This basin is part of the Pantanal, one of the world's largest tropical wetlands, supporting diverse aquatic life and migratory species. Proper treatment is essential to protect this ecologically sensitive downstream environment.
Environmental context
The plant's discharge ultimately reaches the Cuiabá River, a major tributary of the Paraguay River, which drains into the Pantanal wetland ecosystem. The Pantanal is a vast floodplain that supports high biodiversity, including fish, birds, and aquatic plants. Effective wastewater treatment helps prevent nutrient loading and contamination that could harm this fragile environment.
