Overview
ETE Presidente Venceslau serves approximately 35,690 residents in Presidente Venceslau, São Paulo, Brazil. The plant operates under Brazil's national wastewater regulations for medium-sized agglomerations.
ETE Presidente Venceslau is a municipal wastewater treatment plant located in Presidente Venceslau, a city in the state of São Paulo, Brazil. The facility serves a population of around 35,690 people, classifying it as a medium-sized agglomeration under Brazilian sanitation standards. The plant is situated in the southeastern region of Brazil, an area characterized by a subtropical climate and significant agricultural activity. As a plant serving a medium-sized population, ETE Presidente Venceslau is expected to comply with Brazil's national environmental standards, which typically require secondary treatment for such agglomerations. Brazilian regulations, under the National Environmental Council (CONAMA) and state-level agencies, mandate treatment levels that protect receiving water bodies and public health. The plant's treated effluent is discharged into local watercourses 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 irrigation, industry, and drinking water downstream. Proper treatment at this facility is essential to prevent nutrient pollution and maintain water quality in the region's rivers and reservoirs.
Environmental context
The plant discharges into local streams that flow into the Paraná River basin, a major hydrological system draining into the Río de la Plata estuary. This basin supports diverse aquatic life, including migratory fish species, and provides water for agriculture and urban areas. Effective treatment is critical to prevent eutrophication and protect downstream ecosystems in this ecologically sensitive region.
