Overview
ETE I 5 PAULISTA is a wastewater treatment plant serving approximately 33,883 people in Toledo, Paraná, Brazil. It operates under Brazil's national water quality regulations.
ETE I 5 PAULISTA is a wastewater treatment plant located in the Jardim Paulista neighborhood of Toledo, in the state of Paraná, Brazil. The plant serves a population of around 33,883 residents, placing it in the medium-sized agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment facilities are regulated under the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy (Law 9.433/1997). For plants serving populations of this scale, secondary treatment is typically required to meet effluent standards before discharge into receiving water bodies. The plant discharges treated effluent into local watercourses that ultimately drain into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina before emptying into the Río de la Plata estuary. This downstream environment supports diverse aquatic life and is important for regional water supply and agriculture.
Environmental context
The plant's treated effluent enters local streams within the Paraná River basin, which drains into the Paraná River and eventually the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and is a critical water resource for the region. The downstream environment includes sensitive floodplain habitats and wetlands that provide important ecological services.
