ETE Recanto das Taquareiras - Secondary Wastewater Treatment Plant in Alvorada, Brazil

ETE Recanto das Taquareiras is a municipal wastewater treatment plant located in Alvorada, a city in the metropolitan region of Porto Alegre, Rio Grande do Sul, Brazil. The plant serves a small population of 657 residents, reflecting its role in a localized community within the broader urban area. The plant provides secondary treatment, which is the standard biological treatment process required for most municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological degradation of organic matter, followed by sedimentation to remove solids. The plant's discharge volume is recorded at 198.72 cubic meters, indicating its operational scale. The treated effluent is discharged into local water bodies that drain into the Guaíba River basin, which ultimately flows into the Lagoa dos Patos, a large coastal lagoon in southern Brazil. This watershed supports diverse aquatic life and is important for regional water quality. The plant's location within 50 km of the coast means its discharge can influence downstream estuarine and coastal environments.

The plant discharges into the Guaíba River basin, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon is an ecologically sensitive area that supports diverse aquatic life, including fish and migratory birds. The watershed is influenced by urban runoff from the Porto Alegre metropolitan region, making proper wastewater treatment critical for maintaining water quality and ecosystem health downstream.
