ETE GARCA Wastewater Treatment Plant, Graça, Ceará, Brazil

ETE GARCA is a municipal wastewater treatment plant located in Graça, a municipality in the state of Ceará, Brazil. The plant serves a small population of approximately 1,238 residents, reflecting its role in a rural or small-town setting within the semi-arid Nordeste region. As a secondary treatment facility, ETE GARCA provides biological treatment to reduce organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under federal environmental laws and state-level permits, with secondary treatment being the standard for municipal facilities. The plant's discharge volume of 81.65 cubic meters per day aligns with its small service population. The 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 means water resources are particularly sensitive, making proper treatment essential for protecting downstream ecosystems and supporting local water quality.

The treated effluent from ETE GARCA likely enters the Acaraú River basin, which flows northward into the Atlantic Ocean near the city of Acaraú. This watershed supports diverse aquatic life and is important for local agriculture and fishing. The semi-arid climate of Ceará makes water quality management critical for maintaining ecological balance and human use.
