Overview
ETE Francisquinha is a municipal wastewater treatment plant serving Porto Nacional, Tocantins, Brazil. It treats wastewater for approximately 39,577 residents in the northern region of the country.
ETE Francisquinha is a municipal wastewater treatment plant located in Porto Nacional, a city in the state of Tocantins, Brazil. The facility serves an estimated population of 39,577 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. The plant is situated along Avenida Tocantins, reflecting its role in the local urban environment. Brazil's wastewater treatment sector is regulated by federal standards under the National Environmental Council (CONAMA) and state-level environmental agencies. For agglomerations of this scale, secondary treatment is typically required to meet effluent quality standards. The plant's operational details, including specific treatment processes and capacity, are part of the broader municipal sanitation framework aimed at reducing pollution loads. The treated effluent from ETE Francisquinha is discharged into local water bodies that drain into the Tocantins River basin, a major hydrological system in northern Brazil. The Tocantins River flows northward to the Amazon River delta, supporting diverse aquatic ecosystems. Proper treatment at this plant helps protect downstream water quality and the ecological health of the Tocantins-Araguaia watershed.
Environmental context
The plant discharges into the Tocantins River basin, which flows north to join the Amazon River near the Atlantic Ocean. This watershed supports a rich diversity of fish species and riparian habitats. Effective wastewater treatment is critical to prevent nutrient enrichment and maintain water quality in this ecologically sensitive region, which serves as a migratory corridor for aquatic life.
