ETE Centro Paracambi - Secondary Wastewater Treatment Plant in Paracambi, Rio de Janeiro

ETE Centro Paracambi is a municipal wastewater treatment plant located in Vila São José, Paracambi, within the state of Rio de Janeiro, Brazil. The plant serves a small population of 717 residents, reflecting its role in a smaller community within the metropolitan region of Rio de Janeiro. The plant provides secondary treatment, a standard level for municipal wastewater in Brazil, which typically involves biological processes to reduce organic matter and suspended solids. The plant operates under Brazil's national environmental regulations, which require treatment to protect water quality. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean via the Guandu River basin, a major hydrological system in the region. The plant's location within 50 km of the coast means its discharge contributes to the health of downstream ecosystems, including coastal waters.

The plant's discharge enters the local watershed, which is part of the Guandu River basin, a key water source for the Rio de Janeiro metropolitan area. The Guandu River flows into Sepetiba Bay, an important coastal ecosystem supporting mangroves, fish, and migratory birds. Proper treatment helps prevent nutrient pollution and protects the bay's ecological balance.
