ETE JUQUIA Wastewater Treatment Plant, Juquiá, São Paulo, Brazil

ETE JUQUIA is a municipal wastewater treatment plant located in Juquiá, within the state of São Paulo, Brazil. The facility serves a population of about 5,177 people, classifying it as a small-scale treatment operation in the region. It is situated in the southeastern part of Brazil, an area characterized by Atlantic Forest biome and a subtropical climate. The plant provides secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. Secondary treatment is the standard requirement under Brazilian environmental regulations (CONAMA resolutions) for municipal wastewater. The plant's discharge volume of 956.28 cubic meters per day indicates its operational scale. The treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean. The region's watershed supports diverse aquatic ecosystems, including mangroves and estuaries along the coast. Proper treatment at ETE JUQUIA helps protect downstream water quality and the ecological health of the Ribeira de Iguape River basin, which is a significant waterway in southern São Paulo state.

The treated wastewater from ETE JUQUIA flows into local streams that are part of the Ribeira de Iguape River basin, one of the most important river systems in southern São Paulo. This basin drains into the Atlantic Ocean near the town of Iguape, supporting extensive mangrove forests and estuarine habitats. The region's coastal ecosystems are ecologically sensitive, providing nursery grounds for fish and crustaceans, as well as habitat for migratory birds. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain the ecological balance of these downstream environments.
