ETE CASA BRANCA Wastewater Treatment Plant, Casa Branca, São Paulo

ETE CASA BRANCA is a municipal wastewater treatment plant located in Casa Branca, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 23,925 residents, making it a medium-sized facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which require adequate treatment for urban wastewater. As a plant serving a medium-sized agglomeration, ETE CASA BRANCA is expected to provide at least secondary treatment in line with Brazilian standards (CONAMA resolutions). The plant's design and operation are subject to oversight by state environmental agencies such as CETESB in São Paulo. The treated effluent from ETE CASA BRANCA is discharged into local water bodies that drain into the Rio Pardo basin, part of the larger Paraná River system. This watershed supports diverse aquatic life and provides water for downstream communities and agriculture. Proper treatment at this plant helps protect water quality in the region's rivers and reservoirs.

The plant discharges into the Rio Pardo basin, which flows into the Rio Grande and ultimately the Paraná River, one of South America's major river systems. This watershed supports diverse aquatic ecosystems and provides water for irrigation and drinking water supplies. The region's tropical climate and agricultural activity make effective wastewater treatment critical to preventing nutrient pollution and maintaining ecological balance in downstream water bodies.
