ETE Mamanguape - Secondary Wastewater Treatment Plant in Mamanguape, Paraíba

ETE Mamanguape is a municipal wastewater treatment plant located in Mamanguape, within the Região Metropolitana do Vale do Mamanguape in Paraíba, Brazil. The plant serves a population of 1,363 and provides secondary treatment, which is appropriate for a small agglomeration under Brazilian environmental regulations. Secondary treatment at this facility involves biological processes to reduce organic matter and suspended solids, meeting national discharge standards set by the Conselho Nacional do Meio Ambiente (CONAMA). As a small-scale plant, it operates under state-level permitting through the Superintendência de Administração do Meio Ambiente (SUDEMA) of Paraíba, which oversees compliance with water quality criteria for receiving water bodies. The treated effluent is discharged into the Mamanguape River basin, which flows into the Atlantic Ocean near the coast. The region supports diverse aquatic life and is part of a coastal ecosystem that includes mangroves and estuaries, making proper treatment essential for protecting downstream habitats and local communities.

The plant discharges into the Mamanguape River basin, which drains into the Atlantic Ocean along the northeastern coast of Brazil. This coastal region features mangrove forests and estuarine environments that serve as critical nursery habitats for fish and crustaceans. The secondary treatment provided helps reduce nutrient and organic loads, protecting the ecological balance of the downstream estuary and coastal waters.
