ETE Aurora Wastewater Treatment Plant, Aurora, Ceará, Brazil

ETE Aurora is a municipal wastewater treatment plant located in the Mororó district of Aurora, in the state of Ceará, Brazil. The plant serves a population of approximately 3,500 people, reflecting its role in managing domestic wastewater for this small urban community in the semi-arid Nordeste region. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. In Brazil, wastewater treatment plants of this scale are typically regulated by state environmental agencies under federal guidelines such as CONAMA resolutions. The plant's discharge volume of 220.32 m³/day indicates a modest operational scale consistent with the population served. Treated effluent from ETE Aurora is discharged into local water bodies that drain into the Jaguaribe River basin, one of the most important river systems in Ceará. The Jaguaribe River flows eastward to the Atlantic Ocean, supporting irrigation, livestock, and aquatic habitats. Proper treatment at ETE Aurora helps protect downstream water quality and the ecological health of the Jaguaribe watershed.

ETE Aurora discharges into local streams that are part of the Jaguaribe River basin, the largest river system in Ceará. The Jaguaribe River flows approximately 610 km to the Atlantic Ocean near Aracati, supporting diverse aquatic life and providing water for agriculture and human consumption. The semi-arid climate of the region makes water quality management critical for maintaining ecosystem services and preventing eutrophication in downstream reservoirs.
