ETE LAGOA PARQUE JARDIM OASIS - Secondary Wastewater Treatment Plant in Iguatu, Ceará, Brazil

ETE LAGOA PARQUE JARDIM OASIS is a municipal wastewater treatment plant located in the Areias neighborhood of Iguatu, in the state of Ceará, Brazil. The plant serves a population of approximately 4,539 people, classifying it as a small-scale facility within the urban infrastructure of the region. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies. For a plant of this size, secondary treatment meets the typical requirements for inland discharge, ensuring compliance with national effluent standards. The treated effluent is discharged into local water bodies that drain into the Jaguaribe River basin, a major river system in Ceará. The Jaguaribe River flows northeastward into the Atlantic Ocean near the city of Aracati. The plant plays a key role in protecting the water quality of the Jaguaribe basin, which supports agriculture, fisheries, and domestic water supply in the semi-arid region.

The treated effluent from ETE LAGOA PARQUE JARDIM OASIS enters the local drainage network, which flows into the Jaguaribe River basin. The Jaguaribe River is the largest river in Ceará and discharges into the Atlantic Ocean. The downstream environment includes the Jaguaribe River estuary, which supports diverse aquatic life and is an important resource for local communities. The plant's secondary treatment helps reduce organic pollution and nutrient loading, mitigating eutrophication risks in the river and coastal zone.
