Overview
ETE JARDIM DOS LAGOS is a secondary treatment plant serving 4,862 people in Guaíba, Rio Grande do Sul, Brazil. It discharges treated wastewater near the coast, contributing to local water quality management.
ETE JARDIM DOS LAGOS is a municipal wastewater treatment plant located in the Jardim dos Lagos neighborhood of Guaíba, a city in the metropolitan region of Porto Alegre, Rio Grande do Sul, Brazil. The plant serves a population of approximately 4,862 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 for removing organic matter and suspended solids. In Brazil, wastewater treatment is regulated by federal resolutions such as CONAMA 430/2011, which sets discharge standards for treated effluents. For small agglomerations like this, secondary treatment is typically sufficient to meet environmental compliance requirements. The treated effluent is discharged into local water bodies that ultimately drain into the Guaíba River and then into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon system supports diverse aquatic life and is an important ecological corridor for migratory species. The plant's proximity to the coast (within 10 km) means its discharge can influence coastal water quality, making proper treatment essential for protecting downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Guaíba River, which empties into the Lagoa dos Patos, a vast coastal lagoon connected to the Atlantic Ocean. This lagoon is a critical habitat for fish, crustaceans, and migratory birds, and supports local fisheries. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in this sensitive coastal environment.
