ETE Palmital Nova Odessa - Secondary Wastewater Treatment Plant in Americana, São Paulo

ETE Palmital Nova Odessa is a wastewater treatment plant located in the Vila Santa Catarina neighborhood of Americana, within the Campinas metropolitan region of São Paulo, Brazil. The plant serves a population of 2,335 people, reflecting its role in a smaller community within this densely populated state. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated by federal and state environmental agencies, with CONAMA resolutions setting discharge standards. For a plant of this scale, secondary treatment meets typical requirements for inland discharge. The treated effluent from the plant is discharged into local water bodies that ultimately drain into the Piracicaba River basin, a key watershed in São Paulo state. This basin supports agricultural, industrial, and urban water uses and flows into the Tietê River, which is a major tributary of the Paraná River system. Proper treatment helps protect downstream water quality and aquatic ecosystems.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River and eventually the Paraná River system. This watershed supports diverse aquatic life and provides water for agriculture and industry in the region. The surrounding area is part of the Atlantic Forest biome, though heavily urbanized, making effective wastewater treatment critical to reducing nutrient and pollutant loads in downstream water bodies.
