ETE Altaneira Wastewater Treatment Plant, Altaneira, Ceará, Brazil

ETE Altaneira is a municipal wastewater treatment plant located in Altaneira, a municipality in the state of Ceará, Brazil. The plant serves a population of approximately 1,358 people, classifying it as a small-scale facility within the region's sanitation infrastructure. It is situated along Rodovia Jeremias Pereira, in the immediate geographic region of Juazeiro do Norte. The plant provides secondary treatment, which is the standard level required for Brazilian wastewater facilities under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's design and operation align with the requirements set by Brazil's environmental agencies for communities of this size. The treated effluent from ETE Altaneira is discharged into local water bodies, contributing to the protection of the surrounding watershed. The plant plays a key role in preventing untreated sewage from entering the region's rivers and streams, thereby supporting downstream water quality and aquatic ecosystems in the semi-arid landscape of Ceará.

ETE Altaneira discharges treated wastewater into local watercourses that ultimately 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 diverse aquatic life and providing water for agriculture and human consumption. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in this semi-arid region where water resources are particularly sensitive.
