ETE CAIABU Wastewater Treatment Plant, Caiabu, São Paulo, Brazil

ETE CAIABU is a municipal wastewater treatment facility located in Caiabu, a town in the state of São Paulo, Brazil. The plant serves a population of 2,698 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. The plant operates under Brazil's national environmental regulations, which require secondary treatment for communities of this size. With a discharge volume of 289.62 cubic meters, the facility ensures that treated effluent meets quality standards before release into the local environment. The treated wastewater from ETE CAIABU is discharged into a local watercourse that ultimately flows into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and communities downstream. Proper treatment at this plant helps protect water quality in the region.

The treated effluent from ETE CAIABU enters a tributary of the Paranapanema River, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. The Paraná basin supports a rich diversity of fish species and is an important migratory corridor for aquatic life. Secondary treatment at this plant reduces organic pollution and helps maintain the ecological health of the downstream water bodies.
