Overview
ETE Porteiras is a secondary wastewater treatment plant serving the town of Porteiras, Ceará, Brazil. It treats an average daily flow of 133.06 cubic meters.
ETE Porteiras is a municipal wastewater treatment facility located in Porteiras, a town in the state of Ceará, northeastern Brazil. The plant serves a population of approximately 1,173 residents, providing secondary-level treatment to domestic wastewater. It is situated inland, away from coastal areas, and discharges treated effluent into local watercourses. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. As a small-scale facility, it meets the basic treatment standards expected for communities of this size. The plant's treatment process is designed to reduce organic pollutants and suspended solids before discharge. The treated effluent from ETE Porteiras ultimately flows into the Jaguaribe River basin, which is a major water system in Ceará. The river supports local agriculture and provides water for downstream communities. Proper treatment helps protect water quality in this semi-arid region, where water resources are particularly valuable.
Environmental context
ETE Porteiras discharges into the Jaguaribe River basin, which drains into the Atlantic Ocean via the Jaguaribe River estuary. The region is semi-arid, making water quality crucial for local ecosystems and human use. The treatment plant helps reduce nutrient and pathogen loads, protecting downstream aquatic life and supporting sustainable water use in a water-stressed area.
