Overview
ETE CRATEUS 5 is a secondary treatment plant serving 5,223 people in Crateús, Ceará, Brazil. It discharges 423.36 m³/day of treated wastewater into the local watershed.
ETE CRATEUS 5 is a municipal wastewater treatment plant located in Crateús, a city in the state of Ceará, Brazil. The plant serves a population of approximately 5,223 residents, placing it in the small agglomeration category. It is situated inland, far from the coast, and operates within the semi-arid climate of northeastern Brazil. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for inland wastewater treatment. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Treated effluent from ETE CRATEUS 5 is discharged into local water bodies that drain into the Parnaíba River basin, eventually reaching the Atlantic Ocean. The surrounding region is ecologically sensitive, supporting dry forest ecosystems (Caatinga) and seasonal rivers that are critical for local biodiversity and water supply.
Environmental context
The plant discharges into the Parnaíba River basin, which flows northward to the Atlantic Ocean. The Caatinga biome, characterized by seasonal droughts and intermittent streams, relies on treated wastewater to maintain base flows and water quality. Downstream ecosystems include riparian forests and aquatic habitats that support fish and migratory birds. Proper treatment is essential to prevent nutrient enrichment and protect downstream water resources.
