Overview
ETE ORTIGUEIRA is a secondary wastewater treatment plant serving Ortigueira, Paraná, Brazil. It discharges approximately 541.73 thousand cubic meters of treated effluent annually.
ETE ORTIGUEIRA is a municipal wastewater treatment plant located in Ortigueira, within the state of Paraná in southern Brazil. The plant serves a population of approximately 3,847 residents, classifying it as a small-scale facility under Brazilian sanitation standards. The plant provides secondary treatment, which is the minimum level required by Brazilian regulations (CONAMA Resolution 430/2011) for most inland water bodies. This process typically involves biological treatment to reduce organic matter and suspended solids. The plant discharges an annual volume of about 541.73 thousand cubic meters of treated wastewater. The treated effluent is released into a local watercourse within the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The region's watershed supports diverse aquatic life and is important for local agriculture and water supply. Proper treatment helps protect downstream water quality and ecosystem health.
Environmental context
The plant discharges into a tributary of 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 watershed supports diverse aquatic ecosystems, including important fish species and riparian habitats. Secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
