ETE RUA 10 - Secondary Wastewater Treatment Plant in Parauapebas, Pará

ETE RUA 10 is a wastewater treatment plant located in the Cidade Nova neighborhood of Parauapebas, in the state of Pará, Brazil. The plant serves a population of about 6,892 residents, placing it in the small agglomeration category under Brazilian wastewater management frameworks. It operates in the northern region of Brazil, an area characterized by tropical climate and significant mineral extraction activities. The plant provides secondary treatment, which is the standard level required by Brazilian regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Under Brazil's national environmental policies, wastewater treatment plants are subject to licensing and monitoring by state environmental agencies. The treated effluent from ETE RUA 10 is discharged into local water bodies that ultimately 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 and providing water for communities and industries along its course. Proper treatment at this plant helps protect downstream water quality and aquatic life.

The plant discharges into local streams that are part of the Tocantins River basin, which flows into the Amazon River estuary. This region supports rich biodiversity, including fish species important for local fisheries. The secondary treatment process reduces organic pollutants, helping to maintain water quality in downstream ecosystems that are sensitive to nutrient loading and oxygen depletion.
