Overview
ETE Santa Constancia serves Santa Rosa de Viterbo, São Paulo, Brazil, treating wastewater for approximately 18,715 residents. The plant operates under Brazil's national water quality regulations.
ETE Santa Constancia is a municipal wastewater treatment plant located in Santa Rosa de Viterbo, within the state of São Paulo, Brazil. It serves a population of around 18,715 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and state-level regulations, which require secondary treatment for most urban effluents. Plants of this scale typically employ biological treatment processes such as activated sludge or stabilization ponds to meet discharge limits. The treated effluent is released into local watercourses that drain into the Pardo River basin, eventually reaching the Atlantic Ocean via the Rio Grande and Paraná River systems. Proper treatment is essential to protect downstream aquatic ecosystems and water quality for communities relying on these waters.
Environmental context
The plant discharges into tributaries of the Pardo River, which flows into the Rio Grande and then the Paraná River, ultimately reaching the Atlantic Ocean. The region's watershed supports diverse aquatic life and is used for agriculture and drinking water supply. Effective nutrient removal is critical to prevent eutrophication in downstream reservoirs and maintain ecological balance.
