ERQ OESTE is a wastewater treatment plant situated in the Industrial District of Aracaju, in the state of Sergipe, Brazil. The plant serves an estimated population of 31,937, placing it in the medium agglomeration category under Brazilian regulatory frameworks. Its location in the northeastern coastal region subjects it to tropical climate conditions and proximity to sensitive coastal ecosystems. The plant operates under Brazil's national wastewater regulations, which require secondary treatment for urban agglomerations of this size. The designed capacity is reported as 1.00, though the unit is unspecified. Brazilian environmental standards, enforced by state agencies like Administração Estadual do Meio Ambiente (ADEMA) in Sergipe, mandate compliance with discharge limits to protect water quality. The plant's treated effluent likely discharges into the local drainage network, ultimately reaching the Atlantic Ocean via the Sergipe River or nearby coastal waters. This region supports diverse aquatic life and is important for local fisheries and tourism. Proper treatment is critical to prevent nutrient loading and protect downstream ecosystems.
Environmental context
ERQ OESTE is located in the Sergipe River basin, which drains into the Atlantic Ocean near Aracaju. The receiving waters support estuarine and coastal habitats, including mangroves and seagrass beds that provide nursery grounds for fish and crustaceans. The plant's discharge must comply with Brazilian water quality standards to minimize impacts on these ecologically sensitive areas.
