ETE SAHUARA is a municipal wastewater treatment plant located in Caxias do Sul, Rio Grande do Sul, Brazil. The facility serves a population of approximately 31,224 residents, making it a medium-sized plant within the region's sanitation infrastructure. It is situated in the Reserva do Vale neighborhood, part of the São Giácomo district. As a Brazilian wastewater treatment plant, ETE SAHUARA operates under the regulatory framework established by the National Environmental Council (CONAMA) and the National Water Agency (ANA). For plants serving populations between 20,000 and 100,000, Brazilian standards typically require secondary treatment to reduce organic load and suspended solids. It is expected to meet the discharge standards set by state environmental agencies. The treated effluent from ETE SAHUARA is discharged into local water bodies that are part of the Rio Grande do Sul watershed. The region's drainage ultimately flows toward the Lagoa dos Patos, a large coastal lagoon system, and then to the Atlantic Ocean. The plant plays a key role in protecting the water quality of these downstream ecosystems by reducing pollutant loads from urban wastewater.
Environmental context
ETE SAHUARA discharges into the local watershed of Caxias do Sul, which drains into the Rio das Antas basin and eventually reaches the Lagoa dos Patos, a major coastal lagoon in southern Brazil. The lagoon supports diverse aquatic life and is an important migratory corridor for birds. The plant's treatment helps mitigate nutrient and pathogen inputs, protecting the ecological health of this downstream water body.
