ETE CRATEUS 7 is a wastewater treatment facility located in Crateús, a municipality in the state of Ceará, northeastern Brazil. The plant serves a small population of around 959 residents, reflecting its role in a smaller urban agglomeration within the semi-arid interior of the region. The plant provides secondary treatment, a standard level for municipal wastewater in Brazil under the national regulatory framework. Brazil's environmental legislation, including CONAMA resolutions, mandates treatment standards for effluent discharge to protect water quality. For small communities like Crateús, secondary treatment is typical to reduce organic load and pathogens before release. The treated effluent from ETE CRATEUS 7 is discharged into local water bodies that eventually drain into the Atlantic Ocean via the Parnaíba River basin or smaller coastal basins. The semi-arid climate of Ceará makes water resources particularly sensitive, and proper treatment helps preserve downstream aquatic ecosystems and supports local water availability.
Environmental context
The plant discharges into the local watershed of the Parnaíba River basin, which flows northward into the Atlantic Ocean. The region's semi-arid climate means surface waters are limited and ecologically sensitive, supporting diverse aquatic life and serving as critical water sources for local communities. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this fragile environment.
