ETE Biossistema Nogueira - Secondary Wastewater Treatment in Itaipava, Rio de Janeiro

ETE Biossistema Nogueira is a wastewater treatment plant located in Itaipava, a district of Petrópolis in the state of Rio de Janeiro, Brazil. The plant serves a population of 736 and operates with secondary treatment, a standard level for small communities in the region. As a secondary treatment facility, ETE Biossistema Nogueira uses biological processes to reduce organic matter and suspended solids. The plant discharges 172.80 cubic meters of treated wastewater per day. Brazilian regulations, such as CONAMA Resolution 430/2011, set effluent quality standards for such facilities. The plant is situated inland, more than 10 km from the coast, and its treated effluent likely drains into local watercourses that flow toward the Atlantic Ocean. The region is part of the Atlantic Forest biome, known for its rich biodiversity and sensitive water resources.

The plant's treated effluent likely enters small streams in the mountainous region of Petrópolis, which eventually flow into the Paraíba do Sul River basin or directly to coastal lagoons and the Atlantic Ocean. The area is ecologically sensitive, supporting diverse aquatic life and providing water for downstream communities. Proper treatment is essential to protect these water bodies from nutrient pollution and pathogens.
