ETE GUZOLANDIA Wastewater Treatment Plant, Auriflama, São Paulo

ETE GUZOLANDIA is a wastewater treatment plant located in Auriflama, within the state of São Paulo, Brazil. The facility serves a population of approximately 4,032 residents and operates as part of the municipal wastewater infrastructure for the region. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for communities of this size. The plant's discharge volume of 528.96 m³ per day indicates its operational scale. Brazilian environmental laws, such as CONAMA resolutions, set effluent quality standards for secondary treatment facilities. The treated effluent is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is important for agriculture and water supply in the region. The plant's proximity to the coast (within 10 km) means its discharge can influence downstream estuarine and marine environments.

The plant's discharge enters local streams that flow into the Paraná River basin, which drains into the Río de la Plata estuary and the South Atlantic Ocean. The region's aquatic ecosystems support diverse fish species and migratory birds. The proximity to the coast means that nutrients and pollutants from the plant could affect coastal water quality and marine habitats, emphasizing the need for effective secondary treatment.
