ETE Santa Helena PR - Wastewater Treatment Plant in Santa Helena, Paraná, Brazil

ETE Santa Helena PR is a wastewater treatment plant located in Santa Helena, a city in the state of Paraná, Brazil. The plant serves a population of about 10,294 residents, classifying it as a small to medium-sized facility within the region's sanitation infrastructure. The plant operates under Brazil's national environmental standards, which require adequate treatment for municipal wastewater. For a facility serving this population size, typical treatment includes secondary processes to meet discharge quality criteria set by the National Environment Council (CONAMA). The treated effluent from the plant is discharged into local water bodies that eventually drain into the Paraná River basin, a major hydrological system in South America. This river system supports diverse aquatic ecosystems and provides water for agriculture, industry, and communities downstream.

The plant's discharge contributes to the Paraná River basin, which flows into the Río de la Plata estuary. This watershed supports a variety of fish species and is an important resource for regional biodiversity. The area is ecologically sensitive due to agricultural runoff and urban development, making proper wastewater treatment critical for maintaining water quality.
