Overview
ETE FOSSA FILTRO ROSEIRAL is a secondary treatment plant in Cascatinha, Petrópolis, Brazil, serving 368 people. It discharges 86.40 m³/day of treated wastewater into local water bodies.
ETE FOSSA FILTRO ROSEIRAL is a wastewater treatment plant located in the Cascatinha neighborhood of Petrópolis, in the state of Rio de Janeiro, Brazil. This facility serves a small population of 368 residents, reflecting its role in a localized community within the mountainous region of Serra dos Órgãos. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. For a small agglomeration of this size, secondary treatment is appropriate under Brazilian regulations (CONAMA resolutions), which require adequate treatment to protect water quality. The plant discharges 86.40 m³/day of treated effluent. The treated effluent from the plant flows into local streams that are part of the Piabanha River basin, which eventually drains into the Paraíba do Sul River. This river is a major water source for the region and flows into the Atlantic Ocean near Campos dos Goytacazes. The plant's operation helps protect downstream water quality and aquatic ecosystems in this ecologically sensitive mountainous area.
Environmental context
The plant discharges into the Piabanha River basin, a tributary of the Paraíba do Sul River, which flows through the Atlantic Forest biome. This watershed supports diverse aquatic life and provides water for millions of people downstream. The Paraíba do Sul ultimately reaches the Atlantic Ocean, making the plant's secondary treatment important for reducing nutrient and organic pollution in this critical river system.
