ETE RANCHO FUNDO - Advanced Wastewater Treatment in Nova Iguaçu, Rio de Janeiro

ETE RANCHO FUNDO is a wastewater treatment facility located in the Vila Iguaçuana neighborhood of Nova Iguaçu, in the metropolitan region of Rio de Janeiro, Brazil. The plant serves a local population of approximately 2,096 residents, reflecting its role in managing domestic wastewater for a small community within the densely populated Baixada Fluminense region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is consistent with Brazil's national environmental standards, which require appropriate treatment for discharges into sensitive water bodies. The plant's daily discharge volume is 501.12 cubic meters, indicating a modest operational scale. The treated effluent is released into local waterways that ultimately drain into Guanabara Bay, a large coastal estuary in southeastern Brazil. Guanabara Bay is ecologically significant, supporting diverse aquatic life and serving as a critical habitat for fish and bird species. The plant's advanced treatment helps reduce nutrient loading and protect water quality in this important downstream ecosystem.

The plant's treated effluent flows into the Iguaçu River basin, which drains into Guanabara Bay, a major Atlantic estuary. Guanabara Bay supports mangrove forests, fish nurseries, and migratory bird populations, making it ecologically sensitive. Advanced treatment at this plant helps mitigate eutrophication risks and protects downstream water quality in the bay.
