ETE Aramina Wastewater Treatment Plant, Aramina, São Paulo, Brazil

ETE Aramina is a municipal wastewater treatment plant located in Aramina, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 4,810 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. It is situated in the southeastern region of Brazil, an area characterized by a subtropical climate and significant agricultural activity. The plant operates with secondary treatment, which is the standard level required under Brazilian regulations (CONAMA Resolution 430/2011) for most inland water bodies. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The treated effluent from ETE Aramina is discharged into local water bodies that ultimately drain into the Rio Grande, a major tributary of the Paraná River basin. This basin supports diverse aquatic ecosystems and is vital for agriculture, industry, and drinking water supplies in the region. The plant's operation helps protect downstream water quality and public health.

The treated effluent from ETE Aramina flows into local streams that are part of the Rio Grande watershed, which drains into the Paraná River basin. This basin is one of the most important in South America, supporting extensive agricultural activities and providing water for millions of people. The downstream environment includes sensitive aquatic habitats that rely on adequate water quality for biodiversity and ecosystem services.
