ETE BIOSSISTEMA VALE DO CARANGOLA is a wastewater treatment plant located in Petrópolis, within the state of Rio de Janeiro, Brazil. The plant serves a small population of 368 residents, providing secondary treatment to municipal wastewater. It is situated in the mountainous region of Serra dos Órgãos, part of the Atlantic Forest biome, which influences the local hydrology and environmental sensitivity. As a secondary treatment facility, the plant meets the basic standards required for organic matter removal. In Brazil, wastewater treatment is regulated by CONAMA resolutions and state environmental agencies. For small agglomerations like this, secondary treatment is typical and sufficient to reduce pollution loads before discharge. The plant's discharge volume of 86.40 m³/day reflects its small service area. The treated effluent is released into local watercourses that drain into the Piabanha River, a tributary of the Paraíba do Sul River. The Paraíba do Sul basin is a major water source for southeastern Brazil, supplying drinking water to millions and supporting diverse aquatic ecosystems. The plant's operation helps protect downstream water quality in this ecologically important watershed.
Environmental context
