Overview
ETE Polo de Tratamento do Baixo Roger is a major wastewater treatment plant serving João Pessoa, Paraíba, Brazil. It treats wastewater for over 500,000 people, contributing to the sanitation of the region.
ETE Polo de Tratamento do Baixo Roger is a large-scale wastewater treatment plant located in João Pessoa, the capital of Paraíba state in northeastern Brazil. The plant serves a population of approximately 518,445 people, making it a critical infrastructure for the metropolitan region. Its location in the coastal zone of the Northeast Region places it within an area of high environmental sensitivity. As a major agglomeration serving over 500,000 inhabitants, the plant is expected to comply with Brazil's national environmental standards, which require adequate treatment to protect water quality. Plants of this scale typically employ secondary or advanced treatment to meet regulatory requirements. The designed capacity is reported as 1.00, though the unit is unspecified, indicating a substantial treatment capability. The plant's treated effluent likely discharges into local water bodies that drain into the Atlantic Ocean, given its proximity to the coast. The Paraíba do Norte River basin is the primary hydrological feature in the region, and the plant plays a key role in preventing untreated wastewater from reaching sensitive coastal ecosystems. Its operation supports the health of downstream environments, including mangroves and estuarine habitats.
Environmental context
The plant is situated in the coastal zone of Paraíba, within the drainage basin of the Paraíba do Norte River, which flows into the Atlantic Ocean. The downstream environment includes estuarine and mangrove ecosystems that support diverse aquatic life and serve as important nursery grounds for fish and crustaceans. Protecting these habitats from nutrient pollution and pathogens is critical for maintaining regional biodiversity and fisheries.
