ETE BARRO Wastewater Treatment Plant - Barro, Ceará, Brazil

ETE BARRO is a wastewater treatment plant located in Barro, a municipality in the state of Ceará, Brazil. The plant serves a population of approximately 2,900 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. As a facility in Brazil, it operates under national regulations such as CONAMA resolutions and state-level environmental standards, which set effluent quality requirements for discharge into water bodies. The treated effluent is discharged into local watercourses that eventually drain into the Jaguaribe River basin, a major river system in Ceará. This basin supports agricultural activities and provides water for communities downstream, making proper treatment essential for protecting water quality and aquatic ecosystems.

The plant discharges into the Jaguaribe River basin, which flows eastward to the Atlantic Ocean. This semi-arid region relies heavily on surface water for irrigation and domestic use, so maintaining effluent quality is critical to prevent nutrient enrichment and protect downstream aquatic life, including fish species important for local fisheries.
