ETE DOURADO HORIZONTE - Secondary Wastewater Treatment Plant in Horizonte, Ceará

ETE DOURADO HORIZONTE is a municipal wastewater treatment plant located in Horizonte, within the Fortaleza metropolitan region of Ceará, Brazil. The plant serves a small population of approximately 3,576 residents, reflecting its role in a growing urban area in the northeastern region of the country. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is typically required for discharges into inland water bodies. The plant's discharge volume is 311.87 m³/day, indicating a modest operational scale consistent with the population served. The treated effluent from ETE DOURADO HORIZONTE is discharged into local watercourses that drain toward the Atlantic Ocean via the Pacoti River basin. This region of Ceará is characterized by a semi-arid climate, making water quality management critical for downstream ecosystems and water supply. The plant's operation helps protect local streams and the broader coastal environment from untreated sewage pollution.

The plant discharges into the Pacoti River basin, which flows eastward into the Atlantic Ocean near Fortaleza. This coastal watershed supports diverse aquatic life and provides water for agriculture and urban use. Protecting water quality in this semi-arid region is essential for maintaining ecological balance and public health downstream.
