Overview
ETE CRATEUS 9 is a secondary treatment plant in Crateús, Ceará, Brazil, serving approximately 4,797 people. It discharges 388.80 cubic meters of treated wastewater daily.
ETE CRATEUS 9 is a municipal wastewater treatment plant located in Crateús, a city in the state of Ceará, northeastern Brazil. The plant serves a population of about 4,797 residents, placing it in the small agglomeration category under Brazilian regulatory frameworks. It operates with secondary treatment, which is the standard required by Brazilian environmental legislation for inland communities of this size. Brazil's National Environment Council (CONAMA) sets discharge standards for treated wastewater, and plants like ETE CRATEUS 9 must comply with these regulations to protect water quality. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring the effluent meets basic quality criteria before release. The plant's discharge volume is recorded at 388.80 cubic meters per day, reflecting the scale of its service area. The treated effluent from ETE CRATEUS 9 is discharged into local water bodies that eventually drain into the Atlantic Ocean via the Parnaíba River basin or other regional systems. The semi-arid climate of Ceará makes water resources particularly valuable, and proper wastewater treatment is essential for preserving local streams and groundwater. The plant contributes to public health and environmental protection by reducing pollution loads in the region's water network.
Environmental context
The plant discharges into the local watershed of the Poti River, a tributary of the Parnaíba River, which flows into the Atlantic Ocean. The region's semi-arid climate means water bodies are sensitive to pollution, and the plant's secondary treatment helps protect downstream aquatic ecosystems. The Parnaíba River basin supports diverse fish species and is an important water source for communities in northeastern Brazil.
