Overview
ETE BIOSSISTEMA BONFIM is a secondary treatment plant serving 368 people in Cascatinha, Petrópolis, Rio de Janeiro, Brazil. It discharges 86.40 m³/day of treated wastewater into local water bodies.
ETE BIOSSISTEMA BONFIM is a wastewater treatment plant located in the Bonfim neighborhood of Cascatinha, within the municipality of Petrópolis, Rio de Janeiro, Brazil. It serves a small population of 368 residents, reflecting its role in a localized community within the mountainous region of the state. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. The plant operates under Brazil's national environmental regulations, which require adequate treatment for small agglomerations. The discharge volume of 86.40 m³/day indicates a modest scale consistent with the population served. The treated effluent is released into local streams that drain into the Piabanha River, a tributary of the Paraíba do Sul River. This river system is vital for water supply and supports diverse aquatic life in the Atlantic Forest biome. The plant's operation helps protect downstream water quality in this ecologically sensitive region.
Environmental context
The plant discharges into small watercourses that flow into the Piabanha River, which joins the Paraíba do Sul River. This river basin is a major water source for southeastern Brazil and supports Atlantic Forest ecosystems, including endemic fish species. The region's mountainous terrain and high rainfall make proper wastewater treatment essential to prevent nutrient enrichment and sedimentation in downstream rivers and reservoirs.
