ETE Medianeira - Wastewater Treatment Plant in Medianeira, Paraná, Brazil

ETE Medianeira is a municipal wastewater treatment plant located in Medianeira, a city in the state of Paraná, Brazil. The plant serves a population of approximately 8,889 residents, classifying it as a small to medium-sized facility within the region's sanitation infrastructure. Its location in the southern region of Brazil places it within the Paraná River basin, a major hydrological system. Brazil's wastewater treatment standards are governed by federal regulations, including CONAMA resolutions and the National Basic Sanitation Plan (PLANSAB). The plant's designed capacity is 1.00 (likely in a unit such as m³/s or m³/day), indicating a modest operational scale. The treated effluent from ETE Medianeira ultimately discharges into the Paraná River basin, which flows into the Río de la Plata estuary and then the Atlantic Ocean. This watershed supports diverse aquatic ecosystems and is critical for regional water supply, agriculture, and biodiversity. Proper treatment at this plant helps protect downstream water quality and ecological health.

ETE Medianeira discharges into the Paraná River basin, which drains into the Río de la Plata estuary and the Atlantic Ocean. This watershed is ecologically significant, supporting diverse fish species and migratory birds. The plant's location within 50 km of the coast means its effluent can influence coastal water quality, making effective treatment important for protecting downstream marine and estuarine habitats.
