Overview
ETE Ourinhos serves Jacarezinho, Paraná, Brazil, treating wastewater for approximately 32,000 people.
ETE Ourinhos is a municipal wastewater treatment plant located in Jacarezinho, within the state of Paraná, Brazil. The facility serves a population of approximately 32,016, placing it in the medium-sized agglomeration category for Brazilian wastewater infrastructure. The plant is situated inland, more than 50 km from the coast, and operates under Brazil's national environmental regulations. The plant is subject to Brazil's federal wastewater standards, which require secondary treatment for urban areas of this scale. The National Environmental Council (CONAMA) sets discharge quality criteria, and state environmental agencies oversee compliance. Plants serving populations over 20,000 typically must meet stringent effluent limits to protect receiving water bodies. The treated effluent from ETE Ourinhos likely discharges into a local watercourse within the Paraná River basin, which ultimately flows into the Río de la Plata estuary. The region's aquatic ecosystems support diverse freshwater species, and proper treatment is essential to prevent nutrient enrichment and maintain water quality downstream.
Environmental context
The plant is located in the Paraná River basin, one of South America's major hydrological systems. Treated wastewater likely enters a tributary of the Paranapanema River, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This watershed supports important aquatic habitats and is used for water supply and recreation. Effective treatment helps control nutrient loading and protects downstream ecosystems from eutrophication.
