Overview
ETE PEDRO VELHO is a secondary wastewater treatment plant in Pedro Velho, Rio Grande do Norte, Brazil. It serves approximately 5,207 people and discharges 360.29 units of treated effluent.
ETE PEDRO VELHO is a municipal wastewater treatment facility located in Pedro Velho, a municipality in the state of Rio Grande do Norte, Brazil. The plant serves a population of around 5,207 residents, placing it in the small agglomeration category for Brazilian wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for most inland communities. This process typically involves biological degradation of organic matter followed by sedimentation, reducing biochemical oxygen demand and suspended solids before discharge. The treated effluent is discharged into local water bodies that drain toward the Atlantic Ocean via the coastal river systems of northeastern Brazil. The region's semi-arid climate means water resources are particularly sensitive, making proper treatment essential for protecting downstream aquatic ecosystems and public health.
Environmental context
The plant discharges into the watershed of the Rio Grande do Norte coastal region, which ultimately flows into the Atlantic Ocean. The receiving waters support diverse aquatic life and are important for local fisheries and subsistence use. The semi-arid climate of northeastern Brazil makes these water bodies particularly vulnerable to pollution, as low flow conditions reduce dilution capacity.
