Overview
ETE Leste Teresina is a municipal wastewater treatment plant in Teresina, Piauí, Brazil, serving approximately 67,689 people. It operates under Brazil's national environmental regulations.
ETE Leste Teresina is a wastewater treatment facility located in the Ininga neighborhood of Teresina, the capital of Piauí state in northeastern Brazil. The plant serves a population of around 67,689, placing it in the medium-sized agglomeration category for the region. As a Brazilian wastewater treatment plant, it operates under the regulatory framework established by the National Environmental Council (CONAMA) and the National Water Agency (ANA). For a plant of this scale, secondary treatment is typically required to meet effluent standards before discharge into receiving water bodies. The plant's treated effluent is discharged into local waterways that eventually drain into the Parnaíba River basin, one of the major river systems in northeastern Brazil. The Parnaíba River flows northward to the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for agriculture and communities along its course.
Environmental context
The plant's discharge enters the Parnaíba River basin, which flows into the Atlantic Ocean via the Parnaíba Delta, an ecologically sensitive area supporting mangrove forests and diverse aquatic life. The region's semi-arid climate makes water quality management critical for downstream communities and ecosystems that depend on the river's flow.
