ETE Severinia Wastewater Treatment Plant, Severínia, São Paulo, Brazil

ETE Severinia is a municipal wastewater treatment plant located in Severínia, within the state of São Paulo, Brazil. The plant serves a population of approximately 15,681 people, making it a medium-sized facility for the region. It operates under Brazil's national environmental regulations, which require adequate treatment for urban wastewater to protect water resources. Brazilian wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies. For agglomerations of this scale, secondary treatment is typically expected to reduce organic load and pathogens before discharge. It contributes to the local sanitation network managed by municipal or state utilities. The plant discharges treated effluent into local water bodies that drain into the Turvo Grande River basin, part of the Paraná River system. This watershed supports agricultural activities and provides water for downstream communities. Proper treatment at ETE Severinia helps maintain water quality in the region's rivers and reservoirs, which are vital for irrigation, drinking water, and aquatic ecosystems.

The treated effluent from ETE Severinia flows into local streams that are tributaries of the Turvo Grande River, which eventually joins the Paraná River basin. This watershed is ecologically important for the region's biodiversity, supporting fish populations and riparian habitats. The Paraná River system is a major waterway in South America, and maintaining water quality through effective wastewater treatment is crucial for downstream ecosystems and human uses such as agriculture and recreation.
