Overview
ETE Riacho Doce is a secondary wastewater treatment plant in Fortaleza, Ceará, Brazil, serving approximately 1,271 people. It discharges treated effluent near the Atlantic coast.
ETE Riacho Doce is a municipal wastewater treatment plant located in the Riacho Doce neighborhood of Fortaleza, the capital of Ceará state in northeastern Brazil. The plant serves a small population of around 1,271 residents, reflecting its role in local sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is typically required for inland and coastal discharges to protect water quality. The plant's discharge volume is reported at 182.78 units, indicating its operational scale. Situated within 10 km of the Atlantic coast, the plant's treated effluent ultimately reaches the ocean, likely via local drainage channels or the Cocó River basin. The coastal waters off Fortaleza support diverse marine life and are important for local fisheries and tourism. Proper treatment helps minimize nutrient and pathogen loading to this sensitive coastal environment.
Environmental context
The plant discharges into the coastal watershed of Fortaleza, with treated effluent flowing through urban drainage networks to the Atlantic Ocean. The nearshore marine environment supports coral reefs, seagrass beds, and mangrove ecosystems that are ecologically sensitive to nutrient pollution. Effective secondary treatment reduces the risk of eutrophication and protects biodiversity in this tropical coastal zone.
