Overview
ETE Belem Novo serves the Porto Alegre metropolitan region in Rio Grande do Sul, Brazil. The plant treats wastewater for approximately 9,710 people and is located within 50 km of the Atlantic coast.
ETE Belem Novo is a wastewater treatment plant located in the Região Metropolitana de Porto Alegre, Rio Grande do Sul, Brazil. It serves a population of approximately 9,710 people, placing it in the small to medium agglomeration category under Brazilian wastewater management frameworks. Brazil's wastewater treatment regulations, governed by the National Environmental Council (CONAMA) and state environmental agencies, require appropriate treatment levels based on the receiving water body and population served. For plants of this scale, secondary treatment is typically expected to reduce organic load and pathogens before discharge. The plant's treated effluent ultimately flows into the Guaíba River basin, which drains into the Lagoa dos Patos, a large coastal lagoon system. This lagoon supports diverse aquatic life and is an important ecological corridor for migratory species. The proximity to the coast (within 50 km) means that nutrient and pathogen removal are critical to protect downstream estuarine and marine environments.
Environmental context
The plant discharges into the Guaíba River basin, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon connects to the Atlantic Ocean near Rio Grande, supporting a rich ecosystem of fish, crustaceans, and migratory birds. Effective treatment is essential to prevent eutrophication and maintain water quality in this sensitive coastal environment.
Frequently asked questions
ETE Belem Novo is located in the Região Metropolitana de Porto Alegre, in the state of Rio Grande do Sul, Brazil.
The plant serves approximately 9,710 people, classifying it as a small to medium agglomeration under Brazilian wastewater standards.
The treated effluent is discharged into the Guaíba River basin, which flows into the Lagoa dos Patos lagoon system and eventually reaches the Atlantic Ocean.
The plant operates under Brazilian environmental regulations set by CONAMA and the state environmental agency of Rio Grande do Sul, which mandate treatment standards based on population and receiving water body sensitivity.
For plants of this scale, secondary treatment is typically required to reduce biochemical oxygen demand (BOD) and pathogens, often using processes like activated sludge or stabilization ponds.
