ETE Aratuba Wastewater Treatment Plant - Aratuba, Ceará, Brazil

ETE Aratuba is a wastewater treatment plant located in the Coquinho area of Aratuba, a municipality in the state of Ceará, Brazil. The plant serves a population of about 1,527 people, making it a small-scale facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant provides secondary treatment, a level that typically involves biological processes to remove organic matter and suspended solids. Secondary treatment is the minimum standard required for most municipal wastewater in Brazil, ensuring that effluent meets basic quality criteria before discharge. The plant's discharge volume is reported at 432.00 cubic meters per day, reflecting the scale of its operations. The treated effluent from ETE Aratuba is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the river systems of Ceará. The region's watershed supports diverse aquatic life and is important for local agriculture and communities. Proper treatment at this plant helps protect downstream water quality and reduces the risk of eutrophication and contamination in the receiving environment.

ETE Aratuba discharges treated wastewater into local streams that flow through the Ceará river basin, eventually reaching the Atlantic Ocean. The surrounding watershed supports a variety of freshwater species and provides water for agricultural and domestic use. Effective secondary treatment is crucial to prevent nutrient loading and maintain the ecological health of these water bodies, which are sensitive to pollution from small urban centers.
