Overview
ETE Jardim Catarina is a wastewater treatment plant in São Gonçalo, Rio de Janeiro, Brazil, serving approximately 74,205 people. It operates under Brazil's national water quality regulations.
ETE Jardim Catarina is a wastewater treatment plant located in the Trindade neighborhood of São Gonçalo, within the Rio de Janeiro metropolitan area. Serving an estimated population of 74,205, the plant is part of the region's sanitation infrastructure managed by state and municipal authorities. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under Brazil's CONAMA Resolution 430/2011 and the National Water Resources Policy. The plant's designed capacity is 1. Brazil's regulatory framework requires effluent quality monitoring for parameters such as BOD, COD, and suspended solids. The plant discharges into the Guanabara Bay watershed, a highly urbanized estuary that drains into the Atlantic Ocean. The bay supports diverse aquatic life and is a critical ecological and economic resource for the region. The plant's performance directly affects water quality in the surrounding water bodies and downstream coastal areas.
Environmental context
The plant is located within the Guanabara Bay basin, which receives wastewater from multiple municipalities in the Rio de Janeiro metropolitan area. The bay discharges into the Atlantic Ocean and is an ecologically sensitive estuary supporting mangroves, fish, and bird species. Urban runoff and industrial discharges have historically impacted water quality, making effective treatment essential for protecting downstream ecosystems and public health.
