ETE ALGARVE Wastewater Treatment Plant, Alvorada, Rio Grande do Sul, Brazil

ETE ALGARVE is a wastewater treatment plant located in the Alvorada district of Porto Alegre, within the metropolitan region of Rio Grande do Sul, Brazil. The plant serves a population of approximately 19,796 people, classifying it as a medium-sized facility in the region. The plant operates under Brazil's national wastewater regulations, which require appropriate treatment for municipal wastewater. For a facility of this scale, secondary treatment is typically expected to meet environmental standards. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Guaíba River and then into the Lagoa dos Patos, a large coastal lagoon system. This watershed supports diverse aquatic life and is important for regional water quality and ecosystem health.

The plant's discharge contributes to the Guaíba River basin, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon system supports a rich biodiversity, including fish species and migratory birds, and is ecologically sensitive to nutrient loading and pollution from upstream sources.
