ETE SIMAO DIAS Wastewater Treatment Plant, Simão Dias, Sergipe, Brazil

ETE SIMAO DIAS is a wastewater treatment plant located in Simão Dias, a municipality in the state of Sergipe, Brazil. The plant serves a population of approximately 2,122 residents, making it a small-scale facility within the region's sanitation infrastructure. Its location in the northeastern region of Brazil places it in a semi-arid climate zone, where water resources are often scarce and treatment plays a critical role in public health and environmental protection. As a plant serving a small agglomeration, ETE SIMAO DIAS is subject to Brazil's national environmental regulations, including CONAMA Resolution 430/2011, which sets effluent discharge standards. Plants of this scale typically employ lagoon systems or compact treatment units to meet basic secondary treatment requirements. The absence of reported capacity data does not diminish the plant's role in local wastewater management. The treated effluent from ETE SIMAO DIAS likely discharges into a local watercourse that feeds into the broader drainage network of the Sergipe River basin, ultimately reaching the Atlantic Ocean. This downstream connection underscores the plant's importance in preventing untreated sewage from impacting downstream communities and coastal ecosystems. Proper operation helps maintain water quality in a region where water resources are vital for agriculture and human consumption.

The plant's treated effluent likely enters a tributary of the Sergipe River, which flows eastward into the Atlantic Ocean near the city of Aracaju. The Sergipe River basin supports diverse aquatic life and provides water for irrigation and domestic use. The downstream coastal zone includes mangrove ecosystems that are important for fish nurseries and migratory birds. Effective wastewater treatment is essential to prevent nutrient loading and pathogen contamination in these sensitive environments.
