ETE ZUMBI Wastewater Treatment Plant, Horizonte, Ceará

ETE ZUMBI is a wastewater treatment plant located in Horizonte, within the metropolitan region of Fortaleza, Ceará, Brazil. The plant serves a population of about 3,576, classifying it as a small-scale facility under Brazilian sanitation regulations. The plant provides secondary treatment, which is the standard level required by Brazilian environmental legislation (CONAMA resolutions) for most inland facilities. This process typically involves biological treatment to reduce organic matter and suspended solids before discharge. The plant reports a wastewater discharge volume of 311.87 cubic meters per day, indicating consistent operation. The treated effluent from ETE ZUMBI is discharged into local watercourses that drain into the Atlantic Ocean via the Ceará River basin. This discharge supports the ecological health of downstream aquatic habitats, including estuaries and coastal zones. The plant's location more than 10 km from the coast reduces direct marine impact, but its proximity to the Fortaleza metropolitan area underscores the importance of proper treatment for regional water quality.

The plant discharges into the Ceará River basin, which flows into the Atlantic Ocean near Fortaleza. This watershed supports diverse aquatic life and is important for local fisheries and recreation. The downstream environment includes estuarine habitats that are sensitive to nutrient loading and require effective treatment to maintain ecological balance.
