ETE GRANJA Wastewater Treatment Plant, Granja, Ceará, Brazil

ETE GRANJA is a municipal wastewater treatment facility located in Granja, a municipality in the state of Ceará, northeastern Brazil. The plant serves a small population of 273 residents, reflecting its role in a rural or small-town setting. It is situated inland, more than 10 km from the coast but within 50 km, in the semi-arid Nordeste region. The plant provides secondary treatment, which is the standard biological treatment stage required by Brazilian regulations for most municipal wastewater. Brazil's National Environmental Council (CONAMA) sets discharge standards, and secondary treatment typically achieves significant reduction of organic matter and suspended solids. The plant's discharge volume is 26.93 m³/day, indicating a small-scale operation. The treated effluent from ETE GRANJA likely discharges into a local watercourse that drains toward the Atlantic Ocean. The region's watersheds are part of the semi-arid coastal zone, where water resources are seasonally scarce. Proper treatment helps protect downstream water quality and supports local ecosystems, including mangroves and estuaries along the coast.

ETE GRANJA discharges into a local river system that flows toward the Atlantic coast of Ceará. The downstream environment includes seasonal streams and coastal lagoons that support diverse aquatic life and are important for local fisheries. The semi-arid climate means water bodies are sensitive to pollution, making effective treatment critical for maintaining ecological balance and water availability.
