Overview
ETE Santa Cruz do Rio Pardo serves approximately 39,000 people in Santa Cruz do Rio Pardo, São Paulo, Brazil. The plant discharges treated wastewater into local waterways within the Paraná River basin.
ETE Santa Cruz do Rio Pardo is a municipal wastewater treatment plant located in Santa Cruz do Rio Pardo, a city in the state of São Paulo, Brazil. The plant serves a population of around 39,000 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by federal regulations such as CONAMA Resolution 430/2011, which sets effluent quality requirements. For plants of this scale, secondary treatment is typical to meet discharge standards. It operates under the national regulatory framework for water pollution control. The plant's treated effluent is discharged into local water bodies that flow into the Paranapanema River, a major tributary of the Paraná River basin. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. Proper treatment helps protect downstream water quality and ecological health.
Environmental context
