Overview
ETE VILA CATIRI is an advanced wastewater treatment plant in Rio de Janeiro, Brazil, serving 852 people. It discharges 163.62 m³/day of treated effluent into the local watershed.
ETE VILA CATIRI is a wastewater treatment plant located in the Vila Catiri neighborhood of Bangu, Rio de Janeiro, Brazil. It serves a small population of 852 residents, operating as part of the city's municipal sanitation infrastructure. The plant is situated in the Região Metropolitana do Rio de Janeiro, a densely urbanized region with significant water management challenges. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. This treatment level exceeds the secondary standard typically required for small agglomerations under Brazilian regulations (CONAMA resolutions). As an advanced facility, it likely incorporates nutrient removal or disinfection steps to protect receiving waters. The treated effluent from ETE VILA CATIRI flows into local drainage channels that eventually reach the Guanabara Bay, a large estuarine system on the Atlantic coast. Guanabara Bay is ecologically important, supporting mangroves, fish nurseries, and migratory birds. The plant's advanced treatment helps reduce nutrient and pathogen loads to this sensitive water body, contributing to ongoing restoration efforts in the bay.
Environmental context
The plant discharges into the Guanabara Bay watershed, a heavily urbanized estuary that drains into the Atlantic Ocean. Guanabara Bay supports diverse aquatic life, including fish, crustaceans, and mangrove ecosystems, but faces pressures from industrial and domestic pollution. The advanced treatment at ETE VILA CATIRI helps mitigate eutrophication and pathogen contamination in this ecologically sensitive coastal system.
