Overview
ETE ALTOS is a secondary wastewater treatment plant in Altos, Piauí, Brazil, serving approximately 2,981 people. It discharges treated wastewater into the local environment, contributing to regional water quality management.
ETE ALTOS is a municipal wastewater treatment facility located in Altos, a city in the state of Piauí, Brazil. The plant serves a population of about 2,981 residents, operating as part of the region's sanitation infrastructure. Its location in the northeastern region of Brazil places it within a semi-arid climate zone, where water resources are particularly valuable. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under national environmental standards, including CONAMA resolutions, which set discharge limits to protect water quality. For a plant of this scale, secondary treatment meets typical requirements for inland discharge. The treated effluent from ETE ALTOS is discharged into local water bodies, which eventually drain into the Parnaíba River basin, one of the major river systems in northeastern Brazil. This basin supports diverse aquatic life and is important for regional agriculture and drinking water supplies. Proper treatment at this plant helps reduce nutrient and pathogen loads, safeguarding downstream ecosystems and communities.
Environmental context
The plant discharges into local streams that flow into the Parnaíba River basin, which empties into the Atlantic Ocean via the Parnaíba Delta. This watershed supports a variety of fish species and provides water for irrigation and human consumption. The semi-arid climate makes water quality management critical, as low flows can concentrate pollutants. Secondary treatment at ETE ALTOS helps mitigate eutrophication risks and protects the ecological health of the downstream river system.
