Overview
ETE EFLUENTE NOVO HORIZONTE is a secondary treatment plant serving 620 people in Cuiabá, Mato Grosso, Brazil. It discharges 432 m³/day of treated wastewater into the local watershed.
ETE EFLUENTE NOVO HORIZONTE is a wastewater treatment plant located in the Altos da Serra neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a small population of 620 residents and operates with secondary treatment, which is appropriate for its scale under Brazilian environmental regulations. Brazil's wastewater treatment framework, governed by the National Environment Council (CONAMA) and state environmental agencies, requires secondary treatment for most urban effluents to protect water quality. For a plant of this size, secondary treatment ensures removal of organic matter and suspended solids before discharge, meeting typical permit conditions for small agglomerations. 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 pathogen loads entering this ecologically sensitive area, supporting aquatic biodiversity and downstream water quality for communities relying on the river system.
Environmental context
The plant discharges into the Cuiabá River basin, part of the Paraguay River watershed that ultimately drains into the Pantanal wetlands and the Paraná River system. The Pantanal is a vast floodplain ecosystem that supports diverse aquatic life, including fish, caimans, and migratory birds. Secondary treatment helps mitigate eutrophication risks and protects this sensitive downstream environment from excessive nutrient loading.
Frequently asked questions
The plant is located at Rua Itamarati, Altos da Serra, in Cuiabá, Mato Grosso, Brazil. It serves the local community in the Altos da Serra neighborhood.
The plant has a secondary treatment process and discharges approximately 432 m³ of treated wastewater per day. It serves a population of 620 people.
The treated effluent is discharged into the Cuiabá River basin, which flows into the Paraguay River and eventually reaches the Pantanal wetlands. The secondary treatment ensures compliance with Brazilian water quality standards.
The plant operates under Brazil's National Environment Council (CONAMA) resolutions and state-level environmental permits from Mato Grosso's environmental agency. Secondary treatment is required for urban wastewater to protect receiving water bodies.
For small agglomerations in Brazil, secondary treatment is standard, often using technologies like activated sludge or anaerobic reactors. This level of treatment effectively reduces organic pollutants and suspended solids before discharge.
