ETE FOSSA FILTRO CEARA is a municipal wastewater treatment plant located in the Quitandinha neighborhood of Petrópolis, in the state of Rio de Janeiro, Brazil. The plant serves a small population of 368 residents, reflecting its role in a localized community within the broader Região Metropolitana do Rio de Janeiro. The plant provides secondary treatment, a standard level for small agglomerations in Brazil. Under Brazilian regulations (CONAMA resolutions and state-level environmental licensing), secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's discharge volume is 86.40 m³/day, indicating a modest operational scale. The treated effluent is released into the local water system, which drains into the Piabanha River basin, a tributary of the Paraíba do Sul River. The Paraíba do Sul flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais, ultimately reaching the Atlantic Ocean near Campos dos Goytacazes. The watershed supports diverse aquatic life and provides water for agriculture and urban use downstream.
Environmental context
The plant discharges into the Piabanha River basin, part of the larger Paraíba do Sul watershed. The Paraíba do Sul River is a major water source for southeastern Brazil, flowing into the Atlantic Ocean. The downstream environment includes ecologically sensitive areas that support fish populations and riparian habitats. Proper treatment is essential to prevent nutrient loading and protect water quality in this important river system.
