ETE Alambari Avanhandava - Secondary Wastewater Treatment Plant in Avanhandava, São Paulo

ETE Alambari Avanhandava is a municipal wastewater treatment plant located in Avanhandava, within the state of São Paulo, Brazil. The facility serves a population of approximately 3,825 residents, classifying it as a small-scale treatment operation in the region. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring the effluent meets basic environmental standards before discharge. The treated wastewater is discharged into local water bodies that ultimately drain into the Tietê River basin, a major watershed in São Paulo state. The Tietê River flows westward across the state and eventually joins the Paraná River, which empties into the Río de la Plata estuary. The plant's operation helps protect downstream aquatic ecosystems from untreated sewage pollution.

The plant discharges into the Tietê River basin, which flows into the Paraná River and eventually the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The secondary treatment reduces organic load, helping to maintain water quality in downstream rivers and reservoirs.
