ETE Rio Verde Parauapebas - Secondary Wastewater Treatment Plant in Parauapebas, Pará

ETE Rio Verde Parauapebas is a municipal wastewater treatment plant located in the Rio Verde neighborhood of Parauapebas, a city in the state of Pará, Brazil. The plant serves a population of 8,615 and operates with secondary treatment, which is appropriate for a community of this size under Brazilian environmental regulations. The plant discharges an average of 827.71 cubic meters of treated wastewater per day. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the standards set by Brazil's National Environmental Council (CONAMA) for effluent quality. The plant is part of the municipal sanitation infrastructure managed by local authorities. The treated effluent flows into the Rio Verde, a tributary of the Tocantins River basin. This watershed supports diverse aquatic life and provides water for downstream communities. The plant's operation helps protect water quality in the region, which is characterized by tropical rainforest and significant mining activities near Parauapebas.

The plant discharges into the Rio Verde, which flows into the Tocantins River, one of Brazil's major river systems that ultimately reaches the Atlantic Ocean near the Amazon River delta. The Tocantins basin supports rich biodiversity, including fish species and riparian forests. The region's tropical climate and seasonal rainfall patterns influence the river's flow and dilution capacity, making consistent treatment important for maintaining ecological balance.
