ETE TOQUE TOQUE is a municipal wastewater treatment plant located in Niterói, within the Rio de Janeiro metropolitan area, Brazil. The plant serves a population of around 71,320 residents, placing it in the medium agglomeration category under Brazilian regulatory standards. Brazil's wastewater treatment regulations, established by CONAMA resolutions and the National Water Resources Policy, require secondary treatment for urban effluents. For plants of this scale, compliance with discharge standards for biochemical oxygen demand and suspended solids is expected. The plant's designed capacity is 1. The plant discharges into the Baía de Guanabara, a large coastal bay that receives multiple urban and industrial effluents. The bay supports diverse aquatic life and is an important ecological and economic resource for the region. Downstream, the bay connects to the South Atlantic Ocean, making effective treatment critical for coastal water quality.
Environmental context
ETE TOQUE TOQUE discharges into the Baía de Guanabara, a coastal bay in southeastern Brazil that ultimately drains into the South Atlantic Ocean. The bay is ecologically sensitive, supporting mangrove ecosystems, fish nurseries, and migratory bird populations. Urban runoff and untreated sewage have historically impacted water quality, making the plant's treatment role vital for protecting local marine biodiversity and recreational waters.
