ETE Timburi Wastewater Treatment Plant - Timburi, São Paulo, Brazil

ETE Timburi is a wastewater treatment plant located in the rural municipality of Timburi, within the state of São Paulo, Brazil. Serving a population of approximately 1,666, the plant is classified as a small-scale facility, typical of smaller inland communities in the region. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for municipalities of this size. Secondary treatment effectively removes organic matter and suspended solids, reducing the pollutant load before discharge. The plant's discharge volume is recorded at 359.42 cubic meters per day, reflecting the modest scale of the community it serves. The treated effluent is discharged into local streams that eventually flow into the Paranapanema River basin, a major tributary of the Paraná River system. This basin supports diverse aquatic life and is important for regional water supply and agriculture. By providing secondary treatment, ETE Timburi helps protect downstream water quality and the ecological health of the Paranapanema watershed.

The plant discharges into small watercourses within the Paranapanema River basin, which drains into the Paraná River and ultimately the Río de la Plata estuary. The region is characterized by agricultural land use, and the plant's secondary treatment helps mitigate nutrient and organic pollution that could otherwise impact downstream aquatic ecosystems and water quality for rural communities.
