ETE Padre Bernardo Wastewater Treatment Plant, Padre Bernardo, Goiás, Brazil

ETE Padre Bernardo is a wastewater treatment plant located in Padre Bernardo, Goiás, Brazil, serving a population of around 11,717 people. The plant is situated in the Região Integrada de Desenvolvimento do Distrito Federal e Entorno, an area that includes the federal capital Brasília and its surrounding municipalities. As a municipal facility, it plays a key role in managing domestic wastewater for this growing community. Brazil's wastewater treatment sector is regulated by federal laws such as the National Basic Sanitation Law (Law No. 11,445/2007) and the National Environmental Council (CONAMA) resolutions. For a plant of this scale, secondary treatment is typically required to meet effluent standards before discharge. The plant's operational details, including treatment process and capacity, are part of the municipal sanitation plan overseen by state environmental agencies. The treated effluent from ETE Padre Bernardo is discharged into local watercourses that drain into the Paranã River basin, a tributary of the Tocantins River. This watershed supports diverse aquatic life and provides water for agriculture and human consumption downstream. Proper treatment at this plant helps protect water quality in the region's rivers and contributes to the overall health of the Tocantins-Araguaia basin.

The plant's treated effluent flows into streams that are part of the Paranã River sub-basin, which eventually joins the Tocantins River. The Tocantins River is a major Brazilian waterway that empties into the Atlantic Ocean near the Marajó Bay. The region's watershed supports a variety of fish species and is important for local fisheries and agriculture. Maintaining effective wastewater treatment is crucial to prevent nutrient pollution and protect downstream ecosystems.
