Overview
ETE Orlando Dantas is a wastewater treatment plant in Aracaju, Sergipe, Brazil, serving approximately 14,052 people. It operates within Brazil's national sanitation framework, discharging treated effluent into the local watershed.
ETE Orlando Dantas is a wastewater treatment plant located in the São Conrado neighborhood of Aracaju, the capital of Sergipe state in northeastern Brazil. The plant serves a population of around 14,052 residents, classifying it as a small to medium-scale facility within the urban infrastructure of the metropolitan region. As a Brazilian wastewater treatment plant, ETE Orlando Dantas operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies. For agglomerations of this size, secondary treatment is typically required to meet effluent quality standards. The plant's treated effluent is discharged into the local drainage system, which ultimately flows into the Atlantic Ocean via the Sergipe River estuary. This coastal discharge point is within 50 km of the coast, placing it in a sensitive environmental zone where nutrient removal is important to prevent eutrophication in the receiving marine waters.
Environmental context
The plant's discharge enters the Sergipe River basin, which drains into the Atlantic Ocean near the coast of Aracaju. The estuary and coastal waters support diverse aquatic life, including mangroves and fish species. Nutrient loading from wastewater can impact water quality and ecosystem health, making treatment standards critical for protecting downstream habitats.
