Overview
ETE CRATEUS 4 is a secondary-level wastewater treatment plant serving approximately 1,279 people in Crateús, Ceará, Brazil. It discharges 103.68 cubic meters of treated effluent daily.
ETE CRATEUS 4 is a wastewater treatment facility located in Crateús, within the state of Ceará in northeastern Brazil. The plant serves a small population of around 1,279 residents, reflecting its role in local sanitation infrastructure for this inland municipality. The plant operates with secondary treatment, which is appropriate for its scale and aligns with Brazilian regulatory standards for smaller communities. Brazil's national wastewater treatment framework, governed by the National Environmental Council (CONAMA) and state environmental agencies, typically requires secondary treatment for urban effluents to reduce organic load and protect receiving waters. The treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the Parnaíba River basin or coastal watersheds of Ceará. The plant's operation helps safeguard downstream ecosystems and public health in the semi-arid region of northeastern Brazil.
Environmental context
The plant discharges into local streams that are part of the broader drainage network of Ceará state, which flows toward the Atlantic Ocean. The region's semi-arid climate means water resources are scarce, making treatment and reuse critical for maintaining aquatic habitats and supporting local communities. The downstream environment includes seasonal rivers and reservoirs that provide essential water for agriculture and biodiversity.
