ETE ITOBI Wastewater Treatment Plant, Itobi, São Paulo, Brazil

ETE ITOBI is a municipal wastewater treatment plant located in Itobi, a city in the state of São Paulo, Brazil. The plant serves a population of about 5,940 residents, making it a small-scale facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids through biological processes. Secondary treatment is typical for communities of this size in Brazil. The plant's discharge volume is approximately 838 cubic meters per day, reflecting the scale of the local wastewater flow. The treated effluent from ETE ITOBI is discharged into a local watercourse that ultimately drains into the Rio Pardo, a tributary of the Rio Grande, which flows into the Paraná River basin. This watershed supports agricultural activities and provides water for downstream communities. Proper treatment at ETE ITOBI helps maintain water quality in this ecologically and economically important river system.

The plant discharges into a tributary of the Rio Pardo, which flows into the Rio Grande and then the Paraná River basin, one of South America's major river systems. This watershed supports diverse aquatic life and is used for irrigation and drinking water supply. The region's tropical climate with seasonal rainfall means that consistent treatment is important to prevent nutrient loading and algal blooms in downstream water bodies.
