ETE Vila Becker Wastewater Treatment Plant, Dois Irmãos, Rio Grande do Sul

ETE Vila Becker is a municipal wastewater treatment plant located in Dois Irmãos, a city in the state of Rio Grande do Sul, Brazil. The plant serves a population of approximately 2,293 residents, classifying it as a small-scale facility within the regional sanitation infrastructure of the Porto Alegre metropolitan area. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA Resolution 430/2011) for most inland water bodies. This process typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The treated effluent is discharged into local waterways that drain into the Sinos River basin, which flows into the Guaíba River and eventually into the Lagoa dos Patos, a large coastal lagoon in southern Brazil. The Sinos River is an important water source for the region and supports diverse aquatic life, including fish species used for subsistence and recreation. Proper treatment helps protect downstream water quality and ecological health.

The plant discharges into the Sinos River basin, which flows into the Guaíba River and ultimately into the Lagoa dos Patos, one of the largest coastal lagoons in South America. The Sinos River is a vital water resource for the region, supporting aquatic biodiversity and providing water for human consumption and agriculture. Downstream ecosystems include wetlands and estuarine habitats that are sensitive to nutrient loading and pollution, making effective wastewater treatment critical for maintaining ecological balance.
