ETE Tibagi Ponta Grossa - Wastewater Treatment Plant in Ponta Grossa, Paraná

ETE Tibagi Ponta Grossa is a wastewater treatment facility located in the Colônia Dona Luiza area of Ponta Grossa, in the state of Paraná, Brazil. The plant serves a population of approximately 8,812 residents, classifying it as a small-scale municipal treatment facility within the region's sanitation infrastructure. Brazil's wastewater treatment plants are regulated under the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy (Law 9,433/1997). For plants of this size, secondary treatment is typically required to meet effluent standards before discharge into receiving water bodies. It is expected to comply with local environmental permits issued by the environmental agency of Paraná (IAP). The plant discharges treated effluent into local watercourses that drain into the Tibagi River basin, a major tributary of the Paranapanema River, which ultimately flows into the Paraná River and the Río de la Plata estuary. The Tibagi River supports diverse aquatic life and is important for regional water supply and agriculture.

The plant's treated effluent enters local streams that feed into the Tibagi River, which flows through the Paraná state and joins the Paranapanema River. The Paranapanema River is a key tributary of the Paraná River, one of South America's major river systems, draining into the Río de la Plata. The watershed supports diverse ecosystems, including Atlantic Forest remnants, and is important for regional biodiversity and water resources.
