ETE NORTE Wastewater Treatment Plant, Valparaíso, São Paulo, Brazil

ETE NORTE is a wastewater treatment plant located in Valparaíso, within the state of São Paulo, Brazil. It serves a population of approximately 10,627 residents, classifying it as a small to medium-sized facility in the region. The plant is situated inland, more than 10 km from the coast, and operates within the broader context of Brazil's wastewater management infrastructure. The plant's designed capacity is recorded as 1.00 (unit unspecified). In Brazil, wastewater treatment plants are regulated by federal and state environmental agencies, with standards set by CONAMA resolutions. For plants of this scale, secondary treatment is typically expected to meet effluent quality standards, especially when discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local watercourse that drains into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and human consumption. Proper treatment is essential to protect downstream water quality and ecological health.

ETE NORTE is located in the interior of São Paulo state, within the Paraná River basin. The treated wastewater likely flows into a tributary of the Tietê or Paraná River, eventually reaching the Paraná River and ultimately the Río de la Plata estuary. This watershed supports important aquatic habitats and is used for irrigation and drinking water supply. Protecting water quality in this basin is critical for maintaining biodiversity and human health in the region.
