ETE CLEVELANDIA Wastewater Treatment Plant, Clevelândia, Paraná, Brazil

ETE CLEVELANDIA is a wastewater treatment plant located in Clevelândia, a municipality in the state of Paraná, Brazil. The plant serves a population of about 10,384 residents, placing it in the small to medium agglomeration category. It is situated in the southern region of Brazil, an area characterized by a subtropical climate and significant agricultural activity. As a Brazilian wastewater facility, ETE CLEVELANDIA is subject to the country's environmental regulations, including CONAMA Resolution 430/2011 and state-level standards set by the Paraná Environmental Institute (IAP). These regulations mandate treatment levels appropriate for the receiving water body and population served. For a plant of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Iguaçu River basin, one of the major river systems in southern Brazil. The Iguaçu River flows westward and eventually joins the Paraná River, forming part of the larger La Plata Basin. This watershed supports diverse aquatic ecosystems and is important for regional water supply and agriculture.

ETE CLEVELANDIA discharges into local streams that are part of the Iguaçu River basin, which flows into the Paraná River and ultimately the Río de la Plata estuary. The region's watershed supports a variety of freshwater species and is influenced by agricultural runoff. Proper treatment helps protect downstream water quality and aquatic habitats.
