ETE Teixeira Soares - Secondary Wastewater Treatment in Teixeira Soares, Paraná

ETE Teixeira Soares is a municipal wastewater treatment plant located in Teixeira Soares, a city in the state of Paraná, Brazil. The facility serves a population of approximately 1,197 residents, classifying it as a small-scale treatment operation within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and the National Water Resources Policy), secondary treatment is typically required for urban wastewater to protect receiving water bodies. The plant's discharge volume is reported as 356.83 cubic meters, indicating consistent operation. The treated effluent is released into local watercourses that drain into the Paraná River basin, a major hydrological system in South America. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at this plant helps reduce nutrient and pathogen loads, contributing to the ecological health of the region's rivers and reservoirs.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately drains into the Río de la Plata estuary. This watershed supports a variety of fish species and is important for regional biodiversity. Secondary treatment reduces organic pollution, helping to maintain water quality in downstream water bodies used for recreation and water supply.
