ETE JACUTINGA Wastewater Treatment Plant, Avanhandava, São Paulo, Brazil

ETE JACUTINGA is a municipal wastewater treatment plant located in Avanhandava, within the state of São Paulo, Brazil. The facility serves a population of approximately 5,738 residents, classifying it as a small-scale treatment operation under Brazilian regulatory frameworks. The plant provides secondary treatment, which is the standard level required for urban wastewater in Brazil under CONAMA Resolution 430/2011 and other national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges an average of 709.19 cubic meters of treated effluent daily. The treated effluent from ETE JACUTINGA is discharged into local water bodies within the Tietê-Batalha basin, which ultimately drains into the Tietê River, a major tributary of the Paraná River system. This region is part of the interior of São Paulo state, characterized by agricultural and small urban areas. Proper treatment helps protect downstream water quality and aquatic ecosystems.

The plant discharges into the Tietê-Batalha basin, part of the larger Tietê River watershed. The Tietê River flows through São Paulo state and eventually joins the Paraná River, which empties into the Río de la Plata estuary. The receiving waters support diverse aquatic life and are used for irrigation and recreation. Effective secondary treatment reduces organic pollution and nutrient loads, helping to prevent eutrophication and maintain ecological balance in this inland river system.
