ETE DALL ORTO Wastewater Treatment Plant, Nova Odessa, São Paulo

ETE DALL ORTO is a wastewater treatment facility located in the Jardim Dall'Orto neighborhood of Nova Odessa, within the Campinas metropolitan region of São Paulo state, Brazil. The plant provides secondary treatment for a small community of 1,362 residents, reflecting its role in local sanitation infrastructure. As a secondary treatment plant, ETE DALL ORTO employs biological processes to reduce organic matter and suspended solids, meeting Brazilian regulatory standards for effluent quality. Brazil's National Environment Council (CONAMA) sets discharge standards under Resolution 430/2011, which requires secondary treatment for most urban wastewater. Its scale aligns with typical small municipal systems in the region. The treated effluent from ETE DALL ORTO is discharged into local water bodies within the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River system. This watershed supports diverse aquatic life and provides water for agriculture and urban use downstream. The plant's operation helps protect water quality in this ecologically sensitive basin.

ETE DALL ORTO discharges into the Piracicaba River basin, a tributary of the Tietê River, which flows into the Paraná River and ultimately the Río de la Plata estuary. The basin supports diverse aquatic ecosystems and is important for regional water supply. Secondary treatment reduces organic pollution, helping to maintain dissolved oxygen levels and protect fish populations in downstream waters.
