ETE COHAB II Wastewater Treatment Plant, Sobral, Ceará, Brazil

ETE COHAB II is a wastewater treatment plant located in the COHAB II neighborhood of Sobral, a city in the state of Ceará, northeastern Brazil. The plant serves an estimated population of 14,552 residents, classifying it as a medium-sized facility within the region's sanitation infrastructure. As a Brazilian wastewater treatment facility, ETE COHAB II is subject to the country's environmental legislation, including CONAMA resolutions and state-level regulations from Ceará's environmental agency. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the Acaraú River basin. The region's semi-arid climate makes water quality management particularly important for maintaining ecological balance in local streams and supporting downstream communities that rely on these water resources.

The plant discharges into the Acaraú River basin, which flows northward through Ceará state before reaching the Atlantic Ocean near the city of Acaraú. This watershed supports diverse aquatic life and provides water for agriculture and domestic use in the region. The semi-arid climate means that maintaining water quality in these seasonal rivers is critical for ecosystem health and human well-being.
