ETE SAO TIAGO Wastewater Treatment Plant, São Tiago, Minas Gerais

ETE SAO TIAGO is a municipal wastewater treatment plant located in São Tiago, a city in the state of Minas Gerais, Brazil. The plant serves a population of approximately 5,443 people, placing it in the small agglomeration category. It is situated inland, far from coastal areas, and discharges treated effluent into local water bodies. 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 remove organic matter and suspended solids. As a small-scale facility, it plays a key role in protecting local water quality and public health. The treated effluent from ETE SAO TIAGO likely flows into nearby streams or rivers that are part of the Rio Grande basin, which ultimately drains into the Paraná River system and then to the Río de la Plata estuary. This downstream connection highlights the plant's role in preventing pollution in a region that supports agriculture, biodiversity, and water supply for downstream communities.

The plant discharges into local water bodies within the Rio Grande basin, part of the larger Paraná River system. This watershed supports diverse aquatic life and is important for regional agriculture and water supply. The effluent, after secondary treatment, enters streams that flow into the Rio Grande, which eventually reaches the Paraná River and the Río de la Plata estuary. Protecting this chain helps maintain water quality for ecosystems and human use downstream.
