ETE BAIRRO VILA GOULART - Bagé, Rio Grande do Sul Wastewater Treatment Plant

ETE BAIRRO VILA GOULART is a municipal wastewater treatment plant located in Bagé, a city in the state of Rio Grande do Sul, Brazil. The plant serves a population of 1,322 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process required for organic matter removal. In Brazil, wastewater treatment is regulated by the National Environment Council (CONAMA) and state environmental agencies, with secondary treatment being typical for smaller communities. The plant has a reported discharge volume of 360 cubic meters per day. The treated effluent is released into local watercourses that drain into the Rio Negro basin, part of the larger Patos Lagoon system. This lagoon is a major coastal ecosystem in southern Brazil, supporting diverse aquatic life and serving as an important nursery for fish species. Proper treatment at this plant helps protect downstream water quality and ecological health.

The plant discharges into local streams that flow into the Rio Negro, a tributary of the Patos Lagoon system. Patos Lagoon is the largest lagoon in Brazil and a critical estuarine environment, supporting fisheries and migratory birds. The region's subtropical climate and agricultural activity make nutrient management important to prevent eutrophication in downstream waters.
