ETE Turmalina SP - Wastewater Treatment Plant in Turmalina, São Paulo, Brazil

ETE Turmalina SP is a municipal wastewater treatment plant located in Turmalina, a small town in the state of São Paulo, Brazil. The plant serves a population of approximately 1,437 residents, reflecting its role in a small agglomeration. It is situated in the southeastern region of Brazil, an area characterized by a tropical climate and agricultural activity. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland communities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Brazilian environmental legislation, such as CONAMA 430/2011, sets effluent quality standards for discharge into water bodies. The treated effluent is discharged into local watercourses that eventually drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is important for agriculture, hydropower, and water supply. The plant's operation helps protect downstream water quality and ecological health.

The plant discharges into tributaries of the Paraná River basin, which flows through southeastern Brazil and into the Río de la Plata estuary. This basin is ecologically significant, supporting diverse fish species and riparian habitats. The region's agricultural runoff and urban discharges make proper wastewater treatment critical for maintaining water quality and preventing eutrophication in downstream reservoirs and rivers.
