Overview
ETE GRAUNA PANAMA is a wastewater treatment plant serving approximately 22,500 people in Manaus, Amazonas, Brazil. It operates within the Amazon River basin, one of the world's most ecologically significant watersheds.
ETE GRAUNA PANAMA is a wastewater treatment facility located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a population of roughly 22,500 residents, contributing to the city's sanitation infrastructure in the heart of the Amazon rainforest. Brazil's wastewater treatment standards are governed by federal regulations under the National Environmental Council (CONAMA) and state-level environmental agencies. For a plant of this scale, secondary treatment is typically expected to reduce organic load and protect receiving waters. The facility's discharge ultimately enters the Amazon River system, which drains into the Atlantic Ocean. The plant's receiving water body is part of the Amazon basin, the largest river system by discharge volume globally. This watershed supports immense biodiversity, including thousands of fish species and aquatic habitats. Proper treatment is critical to prevent nutrient loading and contamination that could affect downstream ecosystems and communities.
Environmental context
The plant discharges into the Amazon River basin, which flows through the Amazon rainforest and empties into the Atlantic Ocean. This watershed is ecologically sensitive, supporting diverse aquatic life and acting as a major carbon sink. Effective wastewater treatment is essential to minimize impacts on water quality and the region's unique biodiversity.
Frequently asked questions
ETE GRAUNA PANAMA is located in Manaus, the capital city of Amazonas state in northern Brazil. It serves a population of approximately 22,500 people in the region.
The plant serves about 22,476 residents, classifying it as a medium-sized agglomeration under Brazilian sanitation standards.
The treated wastewater is discharged into the Amazon River basin, which eventually flows into the Atlantic Ocean. The plant's discharge contributes to the overall water quality of this vast watershed.
The plant operates under Brazilian federal and state environmental regulations, including CONAMA resolutions that set effluent standards for wastewater treatment plants. These standards aim to protect water quality in receiving water bodies.
For a plant of this size in Brazil, secondary treatment is typically required to reduce biochemical oxygen demand (BOD) and suspended solids. This level of treatment helps protect the receiving waters from organic pollution.
