Overview
ETE CERVIN is a secondary wastewater treatment plant in Rolândia, Paraná, Brazil, serving approximately 7,125 people with a discharge volume of 561.60 cubic meters per day.
ETE CERVIN is a wastewater treatment plant located in the Jardim Catui neighborhood of Rolândia, in the state of Paraná, Brazil. It serves a population of about 7,125 residents, placing it in the small agglomeration category under Brazilian regulatory frameworks. The plant is situated in the southern region of Brazil, an area characterized by subtropical climate and agricultural activity. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Brazil under the National Environment Council (CONAMA) resolutions. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The treated effluent from ETE CERVIN likely flows into local watercourses that drain into the Paraná River basin, one of the largest river systems in South America. The Paraná River ultimately flows into the Río de la Plata estuary. The plant's operation helps protect downstream water quality in a region that supports diverse aquatic life and agricultural water use.
Environmental context
ETE CERVIN discharges treated wastewater into local streams that are part of the Paraná River basin. The Paraná River flows southward through Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. This watershed supports important ecosystems, including riparian forests and wetlands that provide habitat for fish and migratory birds. The plant's secondary treatment reduces organic pollution, helping to maintain water quality in a region where agriculture and urban development exert pressure on water resources.
