ETE ALVINLANDIA - Secondary Wastewater Treatment Plant in Alvinlândia, São Paulo, Brazil

ETE ALVINLANDIA is a wastewater treatment facility located in Alvinlândia, a municipality in the state of São Paulo, Brazil. The plant serves a population of approximately 2,621 people, classifying it as a small-scale treatment facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. As a small agglomeration, it operates under Brazil's national environmental regulations, which require adequate treatment for all urban wastewater before discharge. The treated effluent is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at ETE ALVINLANDIA helps protect water quality in the region's streams and rivers.

The plant discharges into the Paraná River basin, which flows through southeastern Brazil and into the Río de la Plata estuary. This watershed supports important riparian habitats and is a critical water resource for the region. Downstream ecosystems include floodplain forests and wetlands that provide habitat for fish and migratory birds. Effective wastewater treatment helps maintain water quality and ecological balance in this sensitive basin.
