ETE RALF CORONEL SAPUCAIA - Secondary Wastewater Treatment in Coronel Sapucaia, Mato Grosso do Sul

ETE RALF CORONEL SAPUCAIA is a wastewater treatment plant located in Coronel Sapucaia, a municipality in the state of Mato Grosso do Sul, Brazil. The plant serves a population of 1,517 residents, providing secondary-level treatment to municipal wastewater. It is situated in the Centro-Oeste region, near the border with Paraguay. As a secondary treatment facility, the plant employs biological processes to reduce organic matter and suspended solids, meeting the standards expected for small agglomerations in Brazil. Brazilian regulations, such as CONAMA Resolution 430/2011, set effluent quality parameters for wastewater treatment plants, and facilities of this scale typically operate under state-level environmental permits. The treated effluent is discharged into local water bodies, contributing to the protection of the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The region's aquatic ecosystems benefit from the reduction of pollutant loads, supporting biodiversity in the surrounding wetlands and streams.

The plant discharges into local streams that are part of the Paraná River basin, one of South America's major river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina, eventually reaching the Río de la Plata estuary. This watershed supports diverse aquatic life, including migratory fish species, and the plant's secondary treatment helps mitigate nutrient and organic pollution that could otherwise impact downstream ecosystems.
