Overview
ETE REVOLTOSOS is a secondary treatment plant serving Crateús, Ceará, Brazil. It treats wastewater for approximately 8,721 residents and discharges 706.83 cubic meters daily.
ETE REVOLTOSOS is a wastewater treatment plant located in Crateús, within the state of Ceará in northeastern Brazil. The facility serves a population of about 8,721 people, placing it in the small-to-medium agglomeration category for the region. It operates as part of the municipal sanitation infrastructure for Crateús, a city in the semi-arid interior of the state. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and the National Sanitation Plan), secondary treatment is expected for urban wastewater to protect water quality. The plant's discharge volume of 706.83 m³/day aligns with the population served. The treated effluent is discharged into local water bodies that ultimately drain into the Parnaíba River basin, which flows northward to the Atlantic Ocean. The region's semi-arid climate makes water resources particularly sensitive, and proper treatment helps protect downstream ecosystems and water availability for communities and agriculture.
Environmental context
The plant discharges into the Parnaíba River basin, which flows through the Caatinga biome and empties into the Atlantic Ocean near the Parnaíba Delta. This watershed supports diverse aquatic life and is ecologically sensitive due to seasonal droughts. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain water quality for downstream communities and the delta ecosystem.
