ETE SAO JOSE DOS AUSENTES - Secondary Wastewater Treatment Plant in São José dos Ausentes, Brazil

ETE SAO JOSE DOS AUSENTES is a municipal wastewater treatment plant located in São José dos Ausentes, a municipality in the state of Rio Grande do Sul, Brazil. The plant serves a population of 1,154 residents, reflecting its role in a small community in the southern region of the country. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Brazil under the National Environmental Council (CONAMA) regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is released into local water bodies that drain into the Pelotas River basin, which flows into the Uruguay River and eventually into the Rio de la Plata estuary. The plant's operation helps protect downstream aquatic ecosystems and water quality in this region of southern Brazil.

The plant discharges into local streams that are part of the Pelotas River basin, which flows into the Uruguay River and ultimately reaches the Rio de la Plata estuary. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The secondary treatment process helps reduce nutrient and organic pollution, mitigating eutrophication risks in receiving waters.
