ETE APARECIDA DO TABOADO II - Secondary Wastewater Treatment in Aparecida do Taboado, Mato Grosso do Sul

ETE APARECIDA DO TABOADO II is a wastewater treatment plant located in Aparecida do Taboado, a city in the state of Mato Grosso do Sul, Brazil. The plant serves a population of approximately 2,010 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for most urban wastewater. The plant's discharge volume of 528.77 units indicates active operation. Brazil's National Environmental Council (CONAMA) sets discharge standards that such facilities must meet to protect water quality. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Paraná River basin, a major hydrological system in South America. The proximity to the coast (within 10 km) means the discharge may influence coastal ecosystems, requiring careful management to prevent nutrient enrichment and protect aquatic life.

The plant discharges into the Paraná River basin, which flows into the Río de la Plata estuary. This watershed supports diverse aquatic habitats and is important for regional biodiversity. The coastal proximity means treated effluent can affect nearshore marine environments, where nutrient inputs may influence algal growth and water quality. Effective treatment is essential to minimize ecological impacts on downstream ecosystems.
