ETE Ribas do Rio Pardo - Secondary Wastewater Treatment Plant in Ribas do Rio Pardo, Mato Grosso do Sul

ETE Ribas do Rio Pardo is a municipal wastewater treatment plant located in Ribas do Rio Pardo, a city in the state of Mato Grosso do Sul, Brazil. The plant serves a population of approximately 2,062 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment process required under Brazilian regulations (CONAMA resolutions) for urban wastewater. This level of treatment significantly reduces organic matter and suspended solids before discharge. The plant handles an average daily flow of 671.33 cubic meters, reflecting the modest scale of the community it serves. The treated effluent is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at this plant helps protect water quality in the region's streams and rivers, contributing to the ecological health of the broader watershed.

The plant discharges into tributaries of the Paraná River basin, which flows through Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. This watershed supports important riparian forests and aquatic biodiversity, including migratory fish species. Secondary treatment reduces organic pollution, helping to maintain dissolved oxygen levels and prevent eutrophication in downstream water bodies.
