Overview
ETE Polo de Tratamento do Baixo Roger serves João Pessoa, Paraíba, Brazil, treating wastewater for approximately 9,017 people. The plant is located within 50 km of the coast, discharging into the local watershed.
ETE Polo de Tratamento do Baixo Roger is a wastewater treatment plant located in João Pessoa, the capital of Paraíba state in northeastern Brazil. The facility serves a population of about 9,017 residents, placing it in the small agglomeration category under Brazilian sanitation regulations. It is situated in the Vila do S neighborhood, near the Atlantic coast. As a small-scale plant, it is subject to Brazil's national environmental standards, which require adequate treatment to protect water quality. The designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a modest facility. Typical plants of this size employ secondary treatment to meet discharge permits issued by state environmental agencies. The plant's treated effluent likely discharges into local water bodies that drain into the Atlantic Ocean, given its proximity to the coast (within 50 km). This area is part of the Paraíba do Sul basin or smaller coastal basins, supporting estuarine and marine ecosystems. Proper treatment is essential to prevent nutrient pollution and protect downstream aquatic life and coastal water quality.
Environmental context
The plant is located near the Atlantic coast in northeastern Brazil, within the Paraíba state watershed. Treated wastewater likely flows into small rivers or estuaries that empty into the Atlantic Ocean, affecting coastal ecosystems such as mangroves and coral reefs. The region's tropical climate and seasonal rainfall influence dilution and pollutant transport, making effective treatment critical to prevent eutrophication and protect marine biodiversity.
