ETE Pouso do Meio Wastewater Treatment Plant, Gurupi, Tocantins

ETE Pouso do Meio is a wastewater treatment plant located in Gurupi, a city in the state of Tocantins, Brazil. The plant serves an estimated population of 20,780 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. It is situated in the northern region of Brazil, an area characterized by tropical climate and significant seasonal rainfall. The plant operates within Brazil's regulatory framework for wastewater management. The National Environment Council (CONAMA) and state environmental agencies set discharge standards that require adequate treatment for municipal wastewater. Plants serving populations of this scale typically employ secondary treatment processes to meet effluent quality standards. The plant's treated effluent is discharged into local water bodies that drain into the Tocantins River basin, ultimately flowing into the Atlantic Ocean via the Amazon River delta. The surrounding region supports diverse aquatic ecosystems, including riparian forests and wetlands that provide habitat for fish and migratory birds. Proper treatment is essential to protect water quality in this ecologically sensitive watershed.

The plant discharges into local waterways that are part of the Tocantins River basin, which flows northward to join the Amazon River delta before reaching the Atlantic Ocean. This watershed supports diverse aquatic life, including fish species important for local fisheries. The region's tropical climate and seasonal flooding patterns make water quality management critical for maintaining ecological balance and preventing eutrophication downstream.
